Abstract
PURPOSE: To obtain a foamed uniform fine cellular structure having improved strength, chemical resistance, light stability and moisture absorption, by using an unsaturated polyester resin, a specific hydrazide blowing agent and an organic peroxide initiator.
CONSTITUTION: (A) 100pts.wt. of an unsaturated polyester resin, preferably at a composition weight ratio of an unsaturated polymer base to a polymerizable vinyl monomer of 50W90:50W10 is incorporated with (B) 0.1W5pts.wt. of p-toluenesulfonyl hydrazide and/or 4,4'-oxybisbenzenesulfonyl hydrazide as a blowing agent (C) 0.05W2pts. wt. of an organic peroxide, e.g. tert-butyl peroxybenzoate, as an initiator.
USE: A shock-absorbing and heat insulating material.
