Product Introduction

Polyisocyanurate (PIR) is a foaming material made by the polymerization of isocyanate and polyether. Its physical and fire resistance properties are superior to polyurethane, featuring small thermal conductivity and high dimensional stability, making it an excellent organic hard thermal insulation material.

Key Features
  • Fire resistance rated as B1
  • Operating temperature range: -196℃ to +120℃
  • Excellent dimensional stability
  • Customizable cutting in panels and pipes according to customer requirements
Applications

This ideal organic low-temperature heat insulation material combines small thermal conductivity with high dimensional stability. Suitable for a wide temperature range, it's widely used in LNG, ethylene, cold storage, and other low-temperature industries.

Typical PIR Insulation System Structure
PIR Insulation System Structure Diagram
  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 place
  • Keep away from heat sources and protect from sun exposure
  • Inner package: black polyethylene bags
  • Outer package: cartons
Handling Cautions
  • Handle PIR gently, avoiding rolling, collision, and heavy pressure during movement
  • When applied to pipe and equipment insulation, fasten with glass fiber tape or steel band
  • Use a saw for cutting during application
