Abstract
An extruded thin sheet foam is disclosed prepared from a polyolefin resin in which the blowing agent comprises a blend of from about 1 to 25% by weight of carbon dioxide and the balance of C3 to C4 VOCs. Thin foam sheets produced with the blowing agent age about twice as fast as foams prepared with VOCs, are remarkably stable, and can be produced at high throughputs.
