Product Description

Rigid Polyurethane Polyether Polyols Foam Packing Materi

Rigid Polyurethane Polyether Polyols Foam Packing Material is the combined form of pale yellow colored polyether polyol which is available in fluid form, various types of blowing factors, catalysts and other elements. The polyol used to produce this material has high atomic weight.

Polyol produces foam by reacting with isocyanate. The produced Rigid Polyurethane Polyether Polyols Foam Packing Material is capable of suppressing impact and shock. This type of foam is chosen as suitable packing material for breakable items like optical tools, medical accessories, precision tooling, glass items, handicraft items and other delicate goods during their transportation.
