Used in seating for comfort, bumpers for impact resistance, and coatings for corrosion protection and aesthetics.

Long, flexible polyol chains that provide elasticity and low-temperature flexibility. Polyurethane

This reaction is often facilitated by catalysts, such as or organometallic compounds (e.g., dibutyltin dilaurate). To create a solid foam, a "blowing agent" is added; commonly, water reacts with isocyanate to produce CO2CO sub 2 gas, which expands the polymer into a cellular structure. 2.
