ABSTRACT:
An expandable polyolefin composition is disclosed for forming antistatic foam products. The composition includes a polyolefin resin; a hydrocarbyl sulphonate; and an ester of a long-chain fatty acid and polyhydric alcohol. Each of the sulphonate and the ester are present in the composition in an amount sufficient to form a polyolefin product having desirable antistatic properties. A process for extrusion foaming of the composition, and thus formed foam products, are also disclosed.
