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.

Expandable composition, blowing agent, and process for extruded thermoplastic foams

A foam formed from ethylene/vinyl acetate copolymer having a melt index of greater than 1 gram/10 minutes and a vinyl acetate content ranging from about 5 to about 25 weight percent.

Foam comprising ethylene/vinyl acetate copolymer

A foam comprising a blend of a low density polyethylene and an ethylene/alpha-olefin copolymer is disclosed. The ethylene/alpha-olefin copolymer is preferably LLDPE and has a density ranging from about 0.86 to about 0.94 grams/cubic centimeter and a melt flow index of greater than 10 g/10 minutes. A method for producing such foam is also disclosed.
