Propylene-alpha-olefin copolymer compositions with improved foaming window
摘要:
The foaming window for making a foam useful in the manufacture of artificial leather is expanded through the use of a foamable composition comprising (A) a propylene-α-olefin copolymer, (B) a molecular melt (MM) comprising 4,4′-oxydibenzenesulfonylazide (DPO-BSA) and an antioxidant, and (C) a blowing agent. The foaming window can be expanded such that foaming can occur at 220° C. for 20 to 200 or more seconds.
