Description of high activity polyether

high activity polyether,it's Colorless to light yellow transparent viscous liquid.

Highly active polyether contains a large number of primary hydroxyl groups with higher activity than secondary hydroxyl groups of ordinary polyoxypropylene polyols. The reaction rate with isocyanate is faster. It is mainly used in the rapid molding process of foam plastics.

It is mainly used in foam plastic rapid molding processes, such as cold-cured high-resilience foam production process, reaction injection molding (RIM) process, and whole-skin polyurethane semi-rigid foam molding process.
