Product Description
Small Thermal Conductivity Polyiso Pipe Insulation
Polyisocyanurate (PIR) is a foaming material made by the polymerization of 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.
Key Features
- Fire resistance rated as B1
- Operating temperature range: -196℃ to +120℃
- Excellent dimensional stability
- Customizable cutting in panels and pipes to meet specific 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, away from heat sources and protected from sun exposure
- Inner package: black polyethylene bags; Outer package: cartons
Handling Cautions
- Handle PIR gently, avoiding rolling, collision, and heavy pressure during movement
- When applied to pipe and equipment insulation, fasten with glass fiber tape or steel band
- Use a saw for cutting during application
