Abstract

PURPOSE: To obtain the title foam having extremely low density, improved flexibility, nerve, impact resilience, and proper cushioning properties, by foaming again a foamed and crosslinked ethylene-vinyl acetate copolymer resin.
CONSTITUTION: (A) 100pts.wt. of an ethylenevinyl acetate copolymer is blended with (B) not less than 20pts.wt. of a blowing agent (e.g., azodicarbonamide) and (C) not less than 1.0 parts by wt. of a crosslinking agent (e.g., dicumyl peroxide) heated at not lower than the decomposition temperature of the component B under pressure, and molded into the desired shape. The molded article is cooled to preferably 30W120°C while being pressured, removed from a mold, and foamed again to give a foam having a density not more than 0.1 and a impact resilience not less than 40%.
USE: Cushioning materials for vehicles, furnitures, etc., heat insulating material, building materials, etc.
