Polyamide foams, process to make them and applications thereof
摘要:
Closed cell polyamide foams are prepared by subjecting a polyamide resin to inert gases at an elevated pressure and at a temperature above the softening point of the resin and reducing the pressure while the temperature is maintained above the softening point of the resin, resulting in expansion of the resin.
