Abstract

PURPOSE: To provide a blowing agent for thermoplastic resin, composed of a decomposition-type blowing agent and an antioxidant, and capable of producing a highly expanded foam having excellent appearance and touch, stably, without breaking the bubbles at the skin layer of the foamed article.
CONSTITUTION: A blowing agent composed of (A) 100 parts by weight of a decomposition-type blowing agent such as azodicarbonamide, dinitrosopentamethylenetetramine, azobisisobutyronitrile, etc., and (B) (pref. 0.5W10 parts of) an antioxidant pref. having high heat resistance and little adverse effect to the crosslinking of the resin, e.g. octadecyl-3-(3,5-di-t-butyl-4-hydroxyphenyl)-propionate, etc.
