摘要: An expandable thermoplastic composition is disclosed for extrusion foaming wherein the comprises a polyethylene resin; blowing agent comprising blend of about 50% by weight carbon dioxide and either normal butane, isobutane, propane, or mixture any two all three hydrocarbons in admixture with resin ratio one part to 10 parts zinc oxide nucleation an amount from 0.05 0.5 kg per 100 glycerol monostearate aging modifier 5 resin. A process also disclosed.
