Product Introduction
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 requirements

Applications
As an ideal organic low-temperature heat insulation material with excellent thermal conductivity and dimensional stability, PIR is suitable for a wide temperature range. It is widely used in LNG, ethylene, cold storage, and other low-temperature industries.
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 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
Handling Cautions
- Handle PIR 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 with saw during application
