40mm 80mm PIR Polyisocyanurate Insulation Board Thermal Insulation Material

This ideal organic low-temperature heat insulation material features small thermal conductivity and high dimensional stability. Suitable for a wide temperature range, it's widely used in LNG, ethylene, cold storage, and other low-temperature industries.

• Fire resistance rated as B1
• Operating temperature range: -196℃ to +120℃
• Excellent dimension stability
• Customizable cutting in panels and pipes according to requirements

Polyisocyanurate (PIR) is a foaming material made by polymerizing isocyanate and polyether. With superior physical and fire resistance properties compared to polyurethane, this organic hard thermal insulation material offers excellent thermal conductivity and dimensional stability.

• 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, fasten PIR with glass fiber tape or steel band
• Use a saw for cutting during application
