Product Description
Multipurpose PIR Insulation Board for Low Temperature Applications
Polyisocyanurate (PIR) is a high-performance foaming material created through the polymerization of isocyanate and polyether. Offering superior physical properties and fire resistance compared to polyurethane, PIR insulation features minimal thermal conductivity and excellent dimensional stability, making it an ideal organic hard thermal insulation material.
Key Features
- B1 fire resistance rating
- Wide operating temperature range: -196°C to +120°C
- Exceptional dimensional stability
- Customizable panel and pipe cutting options available

Applications
PIR insulation is the ideal organic low-temperature thermal insulation material, featuring minimal thermal conductivity and outstanding dimensional stability. Suitable for a broad temperature range, it is widely used in LNG plants, ethylene production facilities, cold storage units, and other low-temperature industrial applications.
Typical PIR Insulation System Structure
- PIR Shell: Inner layer + middle layer (if required) + 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, or GRP
- Sealant: HS-10-02, Foster 95-50, etc.
- Strapping Material: Stainless steel tape, sub-sensitive tape
Packaging & Storage
- Store in dry, lightproof, shaded, and ventilated areas
- Keep away from heat sources and protect from direct sunlight
- Inner packaging: black polyethylene bags
- Outer packaging: protective cartons
Handling Instructions
- Handle PIR materials gently to avoid rolling, collision, or heavy pressure during transport
- For pipe and equipment insulation, secure PIR with glass fiber tape or steel bands
- Use saws for cutting during installation
