PIR (polyisocyanurate) is a foam material made by reacting isocyanates with polyethers in the presence of a catalyst, offering superior physical and fireproof performance compared to ordinary polyurethane foam. The product features a low thermal conductivity, a wide operating temperature range, and excellent dimensional stability. It can be processed into flat panels, pipe shells, tees, reducers, and other special-shaped parts, making it widely used for insulation in petrochemical refining, fertilizers, cold storage, and LNG facilities.

Reference Standard: ASTM C591,CINI 2.7.01
