Polyurethane is a new type of polymer material, which is made by mixing and foaming black material cyanate ester and white material combination polyether.
Polyurethanes are classified into hard foams, semi-rigid foams, and soft foams.
The
polyurethane screen panels are a kind of mesh products produced from polyurethane. The holes of the sieve plates are: slits, rectangles, circles, squares, and the like.
Polyurethane screen panels insulation material temperature is 120 degrees, high temperature material temperature is 142 degrees, maximum temperature is 150 degrees (can not exceed 500 hours per year). There are currently no polyurethane materials that can reach 250 degrees. The experiment is not mentioned, the actual application has been very extensive.
