Product Description
Polyisocyanurate PIR Pipe Insulation - Durable Good Flammability Resistance
Application
Polyisocyanurate (PIR) is an ideal organic low-temperature thermal 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 is a foaming material made by polymerizing isocyanate and polyether, offering superior physical and fire resistance compared to polyurethane. This organic rigid thermal insulation material combines low thermal conductivity with outstanding dimensional stability.
Key Features
- Fire resistance rated B1
- Operating temperature range: -196°C to +120°C
- Excellent dimensional stability
- Customizable cutting in panels and pipes to meet specific requirements

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, away from heat sources and protected from sun exposure
- Inner package: black polyethylene bags; Outer package: cartons
Cautions
- Handle PIR gently - avoid 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
