Application
This premium organic low-temperature insulation material combines minimal thermal conductivity with outstanding dimensional stability. Suitable for extreme temperature ranges, it is widely used in LNG, ethylene production, 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 dry, lightproof, shady, and ventilated conditions away from heat sources and direct sunlight
- Inner packaging in black polyethylene bags with outer carton packaging
Cautions
- Handle gently - avoid rolling, collision, and heavy pressure during transport
- Secure pipe and equipment insulation with glass fiber tape or steel bands
- Use saw for precise cutting during installation
