Understanding Polyurethane Raw Materials

Polyurethane is created through a chemical reaction between polyols and diisocyanates. Understanding these raw materials helps in selecting the best formulations for specific applications.

Key Components

1. Polyols: These are polyether or polyester-based compounds that provide flexibility and hardness to the final product.
2. Diisocyanates: A critical component that reacts with polyols to form the polyurethane polymer; common types include TDI (Toluene Diisocyanate) and MDI (Methylenediphenyl Diisocyanate).

Common Formulation Issues

Industries often face challenges while working with polyurethane formulations. Below are some common problems and practical solutions:

• Problem: Poor foam stability
