Applications

PIR is an ideal organic low-temperature insulation material with minimal thermal conductivity and excellent dimensional stability. Suitable for a wide temperature range, it's extensively used in LNG, ethylene, cold storage, and other low-temperature industrial applications.

PIR Insulation System Structure

PIR Shell: inner layer + middle layer (if needed) + 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 & Storage

Store in dry, lightproof, shady, and ventilated areas away from heat sources and direct sunlight
Inner packaging: black polyethylene bags; Outer packaging: cartons

Handling Instructions

Handle PIR gently - avoid rolling, collision, and heavy pressure during transport
Secure pipe and equipment insulation with glass fiber tape or steel bands
Use saw for cutting during installation
