Product Description
PH 5.5-7 Polyisocyanurate Building Insulation Materials Foam Board Fire Resistance
Product Description
Polyisocyanurate (PIR) is a high-performance foaming material created through the polymerization of isocyanate and polyether. Offering superior physical and fire resistance properties compared to polyurethane, PIR features minimal thermal conductivity and excellent dimensional stability as an organic hard thermal insulation material.
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
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
PIR is an ideal organic low-temperature thermal insulation material featuring minimal thermal conductivity and excellent dimensional stability. Suitable for a wide temperature range, it is extensively used in LNG, ethylene, cold storage, and other low-temperature industrial applications.
Packing and Storage
- Store in a dry, lightproof, shady, and ventilated area, away from heat sources and protected from sun exposure
- Inner packaging consists of black polyethylene bags with outer carton packaging
Handling Cautions
- Handle PIR gently, avoiding rolling, collision, and heavy pressure during transportation
- When applied to pipe and equipment insulation, secure PIR with glass fiber tape or steel bands
- Use saws for cutting during application
