Applications

This ideal organic low-temperature insulation material features 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

Cautions

Handle gently; avoid rolling, collision, and heavy pressure during moving
When applied to pipe and equipment insulation, fasten with glass fiber tape or steel band
Cut with saw during application
