SD2401
Blend Polyol for making rigid polyurethane foam used for refrigerator
Description
SD2401 formulated polyol is a kind of pouring polyurethane rigid foam system designed with the cyclopentane system. It is specially used for the refrigerator. It contains all the raw materials and auxiliaries necessary for the production of rigid polyurethane foam including the blowing agent. It has the characteristics as following:
n The destiny is uniform distribution. It has strong bonding force with other substrates.
n The light weight, high strength and good dimensional stability
n The low thermal conductivity and good low temperature resistance
Applications
This product is suitable used for polyurethane thermal insulation for refrigerator and freezer.
