WHAT IS POLYURETHANE:

POLYURETHANE

Polyurethane foam is a major component in housing, piping, construction, and nearly every other aspect of modern life.

Polyurethane is different from most plastic materials as it can be tailored to meet various load requirements, specifications and used for varying applications

Polyurethane foams are produced by reacting an equal ratio of di- or polyisocyanurates with polyols, in the presence of water, which acts as the blowing agent. Polyisocyanurates are formed when a higher ratio of di- or polyisocyanate are mixed with a polyol.

 

All rigid foams made from polyisocyanate systems have some form of polyurethane in them and can be called polyurethane foam. The physical properties differ very little at high densities. Polyisocyanurate foams are used in applications where dimensional stability over 200 deg F is required. However, for cryogenic applications, where your pipeline insulation is not exposed to high temperatures, PUF is an acceptable substitution.
