Product Description
Fire Resistant PIR Polyiso Sheet Insulation For Industrial Pipework And Ductwork Systems
Polyisocyanurate foam (PIR), also referred to as PIR, polyiso, or ISO, is a closed cell thermoset polymer formed by reacting a di- or poly-isocyanate with a polyol. Similar to polyurethane foam, PIR offers superior thermal conductivity performance.
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
PIR insulation is an ideal organic low-temperature heat insulation material with small thermal conductivity and high dimensional stability. 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
- Cut with a saw during application
