Rigid Polyether Polyols
Product Name : Rigid Polyether Polyols
Directions
Application
The products are mainly used for preparing the rigid polyurethane foam plastics, which are widely used in refrigerator, cold storage, heat insulation board, coating, alexipharmic ark, heat pipes, buildings, etc. The products show low thermal conductivity factor and excellent dimensional stability. Moreover, they are also important raw material for producing composite polyols.
