InoFoam C4101 series combination polyether
Introduction
C4101 series combination polyether is designed for cyclopentane/HFC-245fa foaming system. It is mainly used to produce heat insulation layer for refrigerator and freezer. It has excellent fluidity, mold release and especially excellent heat preservation performance. The combination polyether is reacted with the polymerized MDI, such as BASF's M20S, Wanhua's PM-200, etc., and the foam has a low thermal conductivity, uniform density distribution, high compressive strength, and good adhesion and dimensional stability.
