Abstract

PURPOSE: To obtain a uniform micro foam having improved heat and weather resistance, by expanding a slightly crosslinked rubber composition obtained by heat- treating a blend of olefin copolymer rubber, an olefin plastic, and a rubber-like material, etc.
CONSTITUTION: A) A blend is obtained by mixing a) 90W50 parts of a peroxide crosslinkable-type olefin copolymer rubber (preferably an ethylene-propylene-ethylidenenorbornene copolymer rubber) and b) 10W50 parts by wt. of a peroxide decomposable-type olefin plastic, preferably propylene-ethylene copolymer, with 5W50 parts by wt. of C) a peroxide non-crosslinkable-type rubber-like material, preferably polyisobutylene, and/or d) a softening agent of mineral oil, the total amount of the ingredient a) and b) being 100 parts by wt. The blend is heat-treated dynamically in the presence of an organic peroxide to give a slightly crosslinked rubber-like composition, which is molten by heat with B) a decomposable-type blowing agent, and expanded to give the desired molded article.
