Product Description
PH 5.5-7 PIR Pipe Insulation Rigid Foam Insulation Material For Construction
Polyisocyanurate (PIR) is one of the most efficient insulation materials used in construction. This product represents an improvement over previously used PUR boards (polyurethane), typically produced as a foam and used as rigid thermal insulation.
Polyisocyanurate PIR is a foaming material made by the polymerization of isocyanate and polyether. It offers superior physical and fire resistance properties compared to polyurethane, with advantages including small thermal conductivity and high 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

- 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 PIR with glass fiber tape or steel band
- Use a saw for cutting during application
