Polyisocyanurate (PIR) is a foaming material made by the polymerization of isocyanate and polyether. Its physical and fire resistance properties are superior to polyurethane. With excellent thermal conductivity and dimensional stability, it belongs to the category of organic hard thermal insulation materials.
Key Features
- Fire resistance rated as B1
- Operating temperature range: -196℃ to +120℃
- Excellent dimensional stability
- Customizable cutting in panels and pipes according to customer requirements
Applications
This ideal organic low-temperature insulation material combines minimal thermal conductivity with outstanding dimensional stability. Suitable for a wide temperature range, it is extensively used in LNG, ethylene production, cold storage, and other low-temperature industrial applications.
Typical PIR Insulation System Structure
- 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
Packing and Storage
- Store in a dry, lightproof, shady, and ventilated area
- Keep away from heat sources and protect from sun exposure
- Inner packaging: black polyethylene bags
- Outer packaging: cartons
Handling Cautions
- Handle PIR gently - avoid rolling, collision, and heavy pressure during transport
- When applying to pipe and equipment insulation, secure with glass fiber tape or steel band
- Use saw for cutting during application
