What are Polyurethane Raw Materials?

Polyurethane raw materials primarily consist of polyols and isocyanates. These components come together in a reaction that forms polyurethane through a process known as polymerization. The specific ratios and types of these materials will dictate the properties of the final product, making it crucial to grasp how they work together.

Key Components

1. Polyols:

   • Types: Polyester-based and polyether-based polyols are the most commonly used.
   • Properties: They determine the physical and chemical characteristics of the final polyurethane, such as flexibility, rigidity, and thermal stability.

2. Isocyanates:

   • Types: The most frequently used isocyanates in polyurethane production are methylene diphenyl diisocyanate (MDI) and toluene diisocyanate (TDI).
   • Properties: Isocyanates play a pivotal role in dictating the reaction with polyols, affecting properties such as hardness and density.
