Product Description
Polyisocyanurate (PIR) Pipe Insulation with Wide Operating Temperature Range
PIR (Polyisocyanurate) foam is an advanced professional cryogenic insulation material offering superior physical properties and fireproof performance compared to standard polyurethane foam, particularly in cold insulation effects and fire retarding capabilities.
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 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
Polyisocyanurate PIR Pipe Insulation Wide Operating Temperature Range 0
  1. PIR Shell: inner layer + middle layer (if necessary) + outer layer
  2. Secondary Vapor Barrier: PAP aluminum foil
  3. Main Vapor Barrier: mastic + fiberglass meshes + mastic
  4. Metal Protective Layer: aluminum alloy plate, stainless steel plate, aluminized steel plate, GRP
  5. Sealant: HS-10-02, Foster 95-50, etc
  6. 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
