High Tensile Strength PIR Foam Insulation Boards Environmentally Friendly Custom Thick
A high degree of automation, efficient series production and great flexibility in special constructions are what set Kaff Rees apart from other manufacturers. Kaff Rees insulation products are manufactured in efficient production, which relies on cutting-edge machines and technologies.
Polyisocyanurate (PIR) is a foaming material made by the polymerization of isocyanate and polyether. Its physical and fire resistance properties are superior to polyurethane. It features small thermal conductivity and high dimensional stability, belonging to the category of organic hard thermal insulation materials.
- Fire resistance rated as B1
- Operating temperature range: -196℃ to +120℃
- Excellent dimensional stability
- Customizable cutting in panels and pipes according to customer requirements

PIR foam is an ideal organic low-temperature heat insulation material featuring small thermal conductivity and high dimensional stability. Suitable for a wide temperature range, it is widely used in LNG, ethylene, cold storage and other low-temperature industries.
- PIR Shell: inner layer + middle layer (if necessary) + outer layer
- Secondary Vapor Barrier: PAP aluminum foil
- Main Vapor Barrier: mastic + fiberglass meshes + mastic
- Metal Protective Layer: aluminum alloy plate, stainless steel plate, aluminized steel plate, GRP
- Sealant: HS-10-02, Foster 95-50, etc
- Strapping Material: stainless steel tape, sub sensitive tape
- Store in a dry, lightproof, shady, and ventilated place, keep away from heat source and protect from sun exposure.
- The inner package is packed in black polyethylene bags and the outer package is packed in cartons.
- PIR shall be handled gently, avoid rolling, collision and heavy pressure during moving.
- When applied to pipe and equipment insulation, PIR shall be fastened with glass fiber tape or steel band.
- Cut it with saw during application.
