PREPARATION PROCESS FOR MULTIMODAL THERMOPLASTIC POLYMER FOAM.

摘要

A multi-modal thermoplastic polymer foam is produced by dispersing blowing agent stabilizer and blowing agent in a heat-plasticized thermoplastic polymer resin at an initial pressure to form a foamable composition, and expanding the composition in the absence of water and at a pressure less than the initial pressure. An independent claim is also included for a manufactured article (preferably thermally insulating).
