Introduction

DJD-101Y series combination polyether is designed for HCFC-141B foaming system. It is mainly used to produce heat insulation layer of 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.
