Cellular thermoplastic resins with mixed blowing agents
摘要:
Thermoplastic resin foams such as polyethylene foams having excellent appearance can be produced with high foaming stability by using a blowing agent composition comprising (a) azodicarbonamide, (b) dinitrosopentamethylenetetramine, and (c) a phenolic or propionate compound such as 1,3,5-tris(3,5-di-t-butyl-4-hydroxybenzyl)-s-triazine-2-4-6-(1H, 3H, 5H)trion.
