ABSTRACT:
Low density foams from polyethylene blends having substantially closed cell structure and improved compressive strength are prepared using gel-forming extrusion technology. The polyethylene blend comprises from about 35 to about 60 weight percent of low density branched polyethylene in admixture with from about 40 to about 65 weight percent of intermediate density linear polyethylene. An exemplary blowing agent is 1,2-dichlorotetrafluoroethane, there being up to about 0.12 gram-mole of such blowing agent per 100 grams of resin blend in the flowable gel.
