COMPRESSIBLE FIRE RETARDANT FOAM

摘要

The present invention relates to a material for thermal and/or acoustic insulation which consists of at least 300 phr, preferably at least 400 phr, but less than 1200 phr, preferably less than 1000 phr, especially preferred less than 800 phr ingredients in total, comprising 100 phr of at least one polymer, of which at least 60 phr, preferably at least 70 phr, especially preferred at least 80 phr is chlorinated polyethylene (CPE), the process of manufacturing such material, wherein the polymeric material is expanded by decomposition of a chemical blowing agent.

主权项

1. An expanded polymeric material consisting of at least 300 phr, but less than 1200 phr ingredients in total, the material comprising:
100 phr of at least one polymer, of which at least 60 phr is chlorinated polyethylene (CPE); wherein the chlorinated polyethylene (CPE) shows a chlorine content of at least 35 wt % according to ISO 1158; and at least 20 phr of at least one further chlorinated organic polymer.
