Applications
PIR is an ideal organic low-temperature insulation material featuring small thermal conductivity and high dimensional stability. Suitable for a wide temperature range, it is extensively used in LNG, ethylene, cold storage, and other low-temperature industrial applications.
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 area away from heat sources and protected from sun exposure
- Inner packaging: black polyethylene bags; Outer packaging: cartons
Handling Cautions
- Handle PIR gently, avoiding rolling, collision, and heavy pressure during movement
- When applied to pipe and equipment insulation, secure PIR with glass fiber tape or steel bands
- Use a saw for cutting during application
