Product Description

Introduction
Polymeric MDI is suitable for injection by moulding method,Rigid polyurethane foams are produced by coating or spraying. At the same time, the semi-rigid foam produced by it can be used in automobile manufacturing and as a sound insulation material
Figured. It can also be used to produce soft self-crusting foams, high resilience soft foams, packaging foams, sealing materials and adhesives.
