Polyisocyanurate Properties




Polyisocyanurate is essentially an improvement on polyurethane. PIR is typically produced as a foam and used as rigid thermal insulation. PIR foam panels laminated with pure embossed aluminium foil are used for fabrication of pre-insulated duct that is used for heating, ventilation and air conditioning systems. Prefabricated PIR sandwich panels are manufactured with corrosion-protected, corrugated steel facings bonded to a core of PIR foam and used extensively as roofing insulation and vertical walls. Other typical uses for PIR foams include industrial and commercial pipe insulation, and carving/machining media.
