Abstract

PURPOSE: The titled resin compound improved in pin-hole formation due to nonuniform dispersion of a powdered component, which is prepared by kneading ethylene-vinyl acetate copolymer resin with a master batch consisting of a powdered component and polyisobutylene rubber.
CONSTITUTION: A resin composition comprising a master batch consisting of a powdered component (A) and polyisoprene rubber (B) of MW 10,000W80,000 and vinyl linkage content ≤25%, and ethylene-vinyl acetate copolymer resin (C). Ethylene-vinyl acetate copolymer resin contg. 3W45wt% vinyl acetate is used. Polyisoprene rubber of MW>80,000 is not used because of difficulty in high concentration of the powdered component and one of MW<10,000 is not used because of deterioration of physical properties. A powdered component for the master batch is a foaming agent, a crosslinking agent, a pigment, a filler, a flame retardant, etc.
