Rigid Polyiso Polyisocyanurate Foam Pipe Insulation Custom Thickness And Color
Kaff Rees' efficient design and production capabilities enable the manufacturing of high-quality insulation materials, including Polyisocyanurate (PIR) foam, with both standardized and customized options available directly from our factory in China.
Polyisocyanurate (PIR) is a superior foaming material created through the polymerization of isocyanate and polyether. It offers enhanced physical properties and fire resistance compared to polyurethane, featuring excellent thermal conductivity and dimensional stability as an organic hard thermal insulation material.
- Fire resistance rated as B1
- Operating temperature range: -196℃ to +120℃
- Excellent dimensional stability
- Customizable cutting in panels and pipes to meet specific requirements

PIR foam is an ideal organic low-temperature insulation material with excellent thermal conductivity and 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, away from heat sources and protected from sun exposure
- Inner package: black polyethylene bags; Outer package: cartons
- Handle PIR gently, avoiding rolling, collision, and heavy pressure during movement
- When applied to pipe and equipment insulation, secure PIR with glass fiber tape or steel band
- Use a saw for cutting during application
