Chapter One: Overview of Foam Tape

What are Foam Tapes?

One kind of pressure-sensitive self-adhesive tape is foam tape. It has one of several different backing materials and is made of foam. It may have adhesive on one or both sides. Foam tapes are, at their most basic level, tapes that are applied to uneven or bumpy surfaces. They can easily hold surfaces like these in place due to their sponge-like, form-fitting characteristics. Single-sided variants work well for activities like sealing, while double-sided types are good for joining two surfaces together. A thicker foam tape may be employed if the surface is rough or has significant irregularities. Foam tapes are available in various foam kinds to meet various substrate needs, and they can be made single- or double-sided by adding adhesive.

Foam tapes can be used in various industries because of their adaptability and ability to provide cushioning, insulation, slip resistance, sound and vibration absorption, weather-proofing, and ozone resistance.

Foam tapes come in various shapes and sizes, including rolls, sheets, and die-cut shapes. Some foam tapes have no drying time, are simple to use, and are pressure sensitive. In addition, it is a very versatile product that can be readily modified to meet a variety of uses and situations across many industries because it is available in various lengths, widths, thicknesses, and colors.

Foam tapes are available in various foam ranges, including open-cell and closed-cell foam in soft, medium, and hard densities. The principal ones are PVC, polyurethane, polyethylene, neoprene, EPDM, and other materials. One will choose the required range based on the application's needs.


Foam Ranges

  • Soft: Foam tape in the soft range is frequently used for air and dust sealing, as lightweight air and dust seals, lightweight cushioning, anti-vibration, and seals.
  • Medium: Foam tape in the medium range is frequently used as a separator to cover gaps, to cushion surfaces, seal seams, and reduce heat transmission.
  • Firm: Where low compression is required, athletic range foam tape is frequently used for sealing, slide pads, glass protection, vibration and sound dampening, and high load-bearing applications.

Properties of Foam Tapes

Foam tapes come in a wide range of thicknesses, adhesives, carriers, sizes, and cell structures, making them suitable for various applications and end uses. Every foam tape has distinct qualities and uses that are good fits.

  • Because foam tape is so flexible, it may be used to fill gaps and conform to link unusual surfaces.
  • Foam tape can often tolerate temperatures between -40°F and 300°F (-40oC to 200oC)
  • Offers strong bonding to account for various thermal expansions
  • Foam tape has a high adhesive strength for various temperature expansions and is resistant to moisture, ultraviolet light from the sun, and solvents.
  • Excellent shock absorption protection and good resistance to compression deformation are provided by this seal, which keeps out dust and moisture or prevents outgassing.
  • Environmentally friendly, free of toxic ingredients, and flame resistant
  • Excellent wettability, ease of die-cutting, suitability for bonding and fixing of varied sizes, and ability to complete watertight sealing are all surface features. Other features include high adhesion, good weather resistance, and resistance to acid and alkali.

How Foam Tape is Used

Joining Items

Nameplates, maps, tiny die-cast components, and other materials can be combined with double-sided tape for attaching two materials, especially those with rough or irregular surfaces; foam tape with double-sided high-performance adhesive works great for this purpose. Acids, oils, grease, and humidity won't damage this tape. It is available in black or white foam.

Mounting

For attaching or hanging big objects, foam tape works incredibly well. For example, foam tape can mount or hang point-of-sale signage, mirrors, photos, towel hooks, and bars in a retail environment.

Cushioning Surfaces

Foam tape can fill a gap that would otherwise allow air, water, or dust to enter by padding the area between two surfaces. Spaces must be sealed using foam tape to prevent interior air or moisture from entering, causing damage or raising heating or cooling costs. The foam can also prevent the paint from scratching by heavy mirrors or picture backs.

Insulation

Because they can hold heat, insulation foam tapes can be used for insulation.

Vibration Reduction

Noise and vibrations in machinery or audio equipment can be reduced with foam tape. Also, in a high-pressure setting, foam tape can help lessen vibrations that could damage anything.

Light-Blocking

Light can be blocked with foam tapes in tiny holes, gaps, and voids in doors and windows.

Mechanical Fastening

Instead of using mechanical fasteners like screws or nuts, which can be expensive and possibly cause friction in high-pressure settings like automobile applications, one might utilize foam tape. The tape is preferable when one doesn't want to leave puncture holes. Foam tape is frequently seen as a more aesthetically-pleasing option because it may be hidden behind a surface.

Considerations When Using Foam Tapes

When choosing which foam tape is suitable for an application, it's crucial to pay special attention to its unique characteristics. Finding the appropriate width, thickness, and adhesive type is crucial when considering foam tapes for a task. In addition, knowing which adhesive kind best suits one’s needs is crucial when making a purchase. Options are rubber, or polyethylene, foam tape, and acrylic foam tape. Finally, selecting the foam tape most appropriate for the application is crucial for the success of the final products.

Guide to Manufacturers

Before using any product, always read the manufacturer's warnings and instructions. These guidelines will serve as the guideline for particular applications of tapes, which exist in various shapes.

Design and Handling

The method the tape is applied, whether it is done automatically or by hand, is just as significant as the tape's strength.

Conformability to Application

Foam tapes are produced using a flexible foam carrier that bridges gaps and connects uneven surfaces. Foam offers cushioning, stress absorption, and vibration dampening, depending on the project's needs, making it useful for many applications.

How Soon it Sticks

When selecting foam tape, this is an important issue to consider. The amount of time a given tape takes to adhere to a given substance varies. This time must be known for planning purposes. The amount of pressure used affects the sticking time as well.

Bonding

It's crucial to think about the surfaces on which one might adhere. Typically, foam tapes feature a strong, quick-stick adhesive that adheres effectively to various surfaces, including but not limited to wood, plastics, chipboard, and corrugated metal.

Preparation of the Surface and Pressure

A strong bond requires meticulous surface preparation. On the material’s surface, contaminants such as dirt, oil, dust, paint, release agents, or other substances may interfere with the adhesive and weaken the binding. For best adherence, ensure dry and clean surfaces before applying the tape. A popular surface cleaning solvent is rubbing alcohol. If required, dry the area with a clean, lint-free cloth, making sure it is completely dry. Apply with strong pressure for better contact within the ideal temperature range recommended by the product's instructions. To activate the adhesive, push firmly and uniformly throughout the tape's surface.

Chapter Two: Foam Cell Structure, Types of Foam Tapes, and Types of Adhesives on Foam Tapes

Foam Cell Structure

Foam cell shapes come in two varieties: open-cell and closed-cell.

Open Cell Foam

Interconnected, softer, more breathable, and simpler to compress are the characteristics of open-cell foam cells. Because of its great porosity, the cell shape in an open-cell foam arrangement allows water, solid particles, and air to pass through the foam material. These foams typically weigh between 1 1/2 and 3 1/4 pounds per cubic foot, making them lighter than conventional. Open-cell foams are soft to the touch, absorb much water, and compress quickly. They are appropriate for sound-absorbing uses, including air conditioner sealing strips and compressed sponges for earbuds, among others. Due to their low density and the substantial ability for expansion and contraction, these foam varieties make packaging and transportation simpler. Although this open-cell foam has good soundproofing properties, it can also trap particles like dust and is mold resistant.

EPDM rubber, urethane foam, polyester urethane, polyether urethane, nitrile, open-cell sponge, sponge rubber, felt, melamine foam, and polyimide foam are the most common materials used to make open-cell foams.


Closed Cell Foam

The bubble walls entirely enclose closed-cell foam bubbles. The bubbles are relatively stiff because they cannot be easily crushed. On the other hand, closed-cell foam structures stop everything from passing through the tape, including liquids, small solid particles, and air. Closed-cell foam is suitable for sealing, dust proofing, waterproofing, and shock absorption of electronic equipment. It has low compression residual rate, low water absorption, good thermal insulation, and cushioning performance. These foams may initially cost more, but they are more affordable over time because of their higher density and improved resistance to moisture and air. They fulfill functions like soundproofing and protective packing because of these advantageous traits. Polyethylene, silicone, PVC, cork, nitrile sponge blend, EVA, neoprene, nitrile foam rubber, and SBR foam rubber are materials used to make closed-cell foam.


Types of Foam Tapes

Foam tape comes in single-sided and double-sided varieties. These categories merely refer to whether the tape is sticky on one or both sides, as each has particular advantages and is more effective for particular applications.

Foam Tape with Adhesive on One Side

Single-sided foam tape is frequently used for sealing and anti-slip purposes. It creates a sturdy solution for various install settings and is simple to cut to size and apply. Single-sided versions are also the best choice when the material's surface is uneven or when shrinkage or expansion may happen. Depending on the materials, certain types of single-sided foam tape also use compression forces to seal against air, dust, or moisture.


Foam Tape with Adhesive on Two Sides

There are several uses for double-sided foam tape, including mounting and gluing. Additionally, many strips might provide a quick and secure way to combine two uneven materials. It is also ideal for handling materials with different expansion rates in environments with frequent temperature changes. This quality is because double-sided foam tape provides flexible, scalable, and efficient levels of stress distribution.


Types of Foam Tapes Depending on The Backing Material

The kind of backing material utilized can also be used to classify it. Following are some examples of the main types:

Neoprene and EPDM Foam Blend

Neoprene EPDM foam comes with either a rubber- or acrylic-based adhesive on one side or both of the closed-cell, black or gray foam. Neoprene EPDM foam is available in various densities and thicknesses, including soft, medium, and firm. Neoprene foam tape is a durable indoor and outdoor tape. It works best for situations involving sealing and weatherstripping.

Neoprene EPDM is perfect for vibration dampening, weatherstripping, and gaskets. Neoprene EPDM foams can tolerate various temperatures and resist acids, alkalis, ozone, and oxidation.


Acrylic Foam Tape

The extremely flexible acrylic adhesive is elastic and flexible. It has a high level of strength and long-lasting durability. Acrylic foam tape has a comparatively strong adhesive bond, making it perfect for projects exposed to the elements, especially wetness or hot or fluctuating temperatures. In addition, it is resistant to chemicals and elements. One can pick an acrylic adhesive based on these qualities to seal a window or repair an HVAC system.

Acrylic foam tape can attach outdoor objects exposed to intense heat and dampness. In addition, it serves as weather stripping, insulation, a seal for HVAC systems to tolerate temperature changes, and gaskets for garage or shed doors.


Polyurethane Tapes

Another material that is frequently utilized as a substrate for foam tapes is polyurethane. It is a potent, long-lasting substance that can tolerate extreme temperatures. It is a conformable foam for indoor or outdoor applications that are covered. In addition, low-density polyurethane foam tapes offer effective insulation.

  • Polyester Foam: Available in densities ranging from 1.5 to 6 pounds per cubic foot, this open-cell, non-reticulated foam is charcoal grey in appearance. Polyether foams are excellent for light insulation and sound and dust barriers. With various adhesives, polyester foams can be laminated to fulfill the needs of any particular application. Compared to polyether, polyester foams are more resistant to alcohols and hydrocarbons.
  • Polyether Foam: Available in densities ranging from 1-5.5 pounds per cubic foot, this open-cell, non-reticulated foam appears grey. Although they perform better in moist or wet situations than polyester foams, polyether foams have a lower tensile strength. Polyether foams are also easily produced to customer requirements and can be provided with or without glue.

PVC Vinyl Foam

Best in situations when long-term outside exposure is anticipated, and impact cushioning is a need. PVC vinyl closed cell foam is available in a wide range of thicknesses and densities in either black or grey. One can order PVC foam with or without glue. PVC foams are frequently used in seals and gaskets that prevent air, dust, and mild wetness. PVC foams can be produced to fit any particular purpose and are resistant to most solvents and chemicals. In addition, a dependable and chemically stable adhesive option is provided by PVC foam tape. There are numerous lengths, widths, and thicknesses from which to choose.


Polyethylene (PE) Foam Tape

Foam tapes are frequently attached to polyethylene, a form of plastic. It is a smooth, light substance that is simple to handle. Polyethylene foam tapes combine a conformable closed-cell foam with a rubber-based adhesive. Several surfaces are initially well-bonded by the rubber-based adhesive. As a result, there are numerous thicknesses and widths of polyethylene foam tape. To accommodate any application demands, polyethylene foam tape is available in white or black with adhesive on either one or both sides. Polyethylene is the perfect tape for connecting, mounting, sealing, and gasketing. POP displays, nameplates, signs, wire, and cable mounting clips are some examples of common applications for polyethylene foam tape. Polyethylene foam tape's rising demand frequently necessitates specific manufacture.

PE foam tape excels in reducing noise and vibration and accounting for materials that expand or contract at various rates. Because it adheres effectively to uneven surfaces and surfaces frequently encountered indoors, like plastic, polyethylene foam tape is preferred for indoor application. Due to its exceptional conformability, it will adapt to surfaces with uneven textures and rough edges. In addition, it makes for excellent padding because of its excellent compressibility. PE foams are a cost-effective way to seal doors and offer long-lasting waterproofing between surfaces. When burned, they also don't release any harmful pollutants.


Rubber Foam Tapes

The base for foam tapes has historically been made of rubber, a natural substance. It is a potent, long-lasting substance with a good abrasion resistance that can sustain high temperatures. It is a self-stick tape that is strong, long-lasting, and a little compressed. Rubber foam tape has several applications, such as a gasket and weatherstrip, to support and stabilize large appliances. Additionally, it can lessen rattles, vibrations, and squeaks on cars, trucks, and boats.


Silicone Foam Tapes

Foam tapes frequently adhere to silicone, a synthetic material. Silicone foam tape provides an appropriate adhesive option for sealing and gasket applications where a temperature requirement above 150 degrees is necessary. This tape is also employed as a food-safe product. It also has a lot of use in aerospace, heavy engineering, marine, and space research. This selection can assist in achieving the highest performance and quality levels. They come in a range of thicknesses and have great insulating qualities. High-temperature gaskets, insulation, and spacers can all be adhered to with silicone foam tape because it offers a strong, reliable connection.


Neoprene/EPDM/SBR Foam Tapes

Neoprene, EPDM, and SBR are combined in a closed-cell foam blend to create a gasket component suitable for various industrial and mechanical applications where resistance, adaptability, and affordability are essential. Combining the best features of these three polymers results in a fantastic product that can be used in a wide range of different indoor and outdoor applications. Neoprene/EPDM/SBR mixtures are also used in electrical enclosures. They can encapsulate machinery and enclosures that house electrical components and circuitry. Blends of neoprene, EPDM, and SBR are beneficial for HVAC. The closed-cell neoprene/EPDM/SBR blend is a perfect gasket to seal connections, ducts, panel doors, and other locations because of its capacity to eliminate air leakage. Weatherproofing and gaskets can be made from neoprene/EPDM/SBR blends. When temperatures fluctuate from -40° F to +200° F during the application procedure, closed-cell neoprene/EPDM/SBR blends work effectively. Because it is resistant to sunshine, ozone, and oxidation, it performs well as a gasket in many outdoor applications.

The automotive industry can also benefit from this kind of foam tape. Most pressure-sensitive adhesive tapes can adhere gaskets to metal and plastic surfaces for sealing and cushioning applications, thanks to their access to the closed-cell structure.


Neoprene/EPDM/SBR blends offer a versatile gasket material that is frequently affordable and effective in various applications. If necessary, a pressure-sensitive adhesive (PSA) can be laminated onto one or both sides of this material. After that, the material can be trimmed to size and is frequently offered in various thicknesses. These blends can also be precisely waterjet cut, die cut, or sliced to width.

Types of Adhesives on Foam Tapes

Acrylic adhesive, rubber adhesive, and silicone adhesive are the three types of adhesives most frequently used in foam tape.

  • Acrylic Adhesive: The most typical adhesive for foam glue is an acrylic adhesive. Acrylic foam tape is ideal for indoor and outdoor applications because of its strength, high-temperature tolerance, and excellent UV resistance.

    • Furniture Decorative Panel Fixing: To provide cabinets or closets with an attractive appearance, decorative panels made of glass, wood, and glazing are often found there. The foam tape supports a certain amount of the panel's weight, which can be supported by the foam tape, which also completes a solid and long-lasting fixation between various materials.
    • Glass Partition Wall Bonding: Aluminum or glass profiles can be combined using double-sided foam tape. This material's transparency produces an undetectable bonding effect for partition walls that is ideal for filling in any gaps in the project.
    • Curtain Wall Bonding: Decorative walls can be covered to create striking architectural façades. Because they produce a cleaner and more aesthetically-pleasing look while meeting the strict requirements of external weather resistance, foam tapes are a great substitute for conventional mechanical fixing methods.

    Benefits of Foam Tape

    Foam tape is incredibly flexible and may be customized indefinitely to meet the needs of almost any application. As a result, foam tape has many advantages, such as extended service life, adaptability, flexibility, and time and cost efficiency.

    • Saving Time: Foam tape saves time by replacing the requirement for fasteners, liners, and sealing materials when used as an interior adhesive in devices and equipment. This device can dramatically reduce overall manufacturing labor and time requirements by requiring less waste management and installation time, increasing production efficiency.
    • Material Cost Reduction: Foam tapes, which are cheap and simple to make and shape to precise measurements, can cut down on material costs. Suppliers can satisfy the project's requirements by converting to tape using techniques like lathe splitting and die cutting. As a result, they deliver enormous rolls or logs with accuracy in dimensions while maintaining a low overhead cost for the materials.
    • Longer Service Life: Extremely durable foam tapes maintain their characteristics in various challenging circumstances. Most significantly, the PVC foam tape is resistant to harm from fuels, flames, chemicals, solvents, and ultraviolet radiation. Furthermore, since PVC foam has a closed-cell structure, it doesn't absorb moisture easily and won't rot. In addition, PVC is vibration-resistant and has a great fatigue life. Given that PVC foam is resistant to many factors and still maintains compatibility with various adhesives and resins, it is a practical choice for a lifetime.
    • Foam tapes are flexible and adaptive: they expand and contract due to temperature and atmospheric pressure variations, but they maintain a strong binding. Traditional fasteners will get looser during repeated expansion and contraction. Foam tapes are adaptable, bending with heat expansion and contracting to maintain their adhesive. They can use designs with double-sided adhesive, resistant linings, and specialty materials and are adaptable to fulfill the demands of any specific application.
