What is Isocyanate?

Isocyanates, crucial in polyurethane production, include TDI variants (2,4-TDI, 2,6-TDI). TDI-100 suits castable polyurethane, T-80 is widely used, and T-65 is for high-rebound foams. Reactivity varies due to molecular structures. TDI is a transparent liquid with a coloration tendency, distinctive odor, and solidification point influenced by composition.

What is the difference between high-density foam and high-resilience foam?

The difference between high-density foam and high-resilience foam lies in density and structure. High-density foam, suitable for sound-absorbing cotton and soft packaging, has high density and greater mass. On the other hand, high-resilience foam, made with polyether polyols, boasts excellent resilience and breathability, primarily used in car seats and furniture. The two types differ significantly in principles, applications, and characteristics.
