Poly A


Product Description

Poly A is a dark-colored polyol that is mixed with the honey-colored Poly B, and isocyanate, to create a polyurethane foam.  This is a chemical reaction that produces a change in color and state, emits an odor, and releases heat.  The two liquids produce a colloidal foam that expands 15-20 times its original volume.
