Product Description
OEM Fire Resistant PIR Insulation Board Organic Hard Thermal Insulation Material
Polyisocyanurate (PIR) is a high-performance foaming material created through the polymerization of isocyanate and polyether. Offering superior physical properties and fire resistance compared to polyurethane, PIR insulation features minimal thermal conductivity and excellent dimensional stability as an organic hard thermal insulation material.
Key Features
  • Fire resistance rated B1
  • Operating temperature range: -196℃ to +120℃
  • Exceptional dimensional stability
  • Customizable panel and pipe cutting options

Applications
As an ideal organic low-temperature insulation material, PIR boards combine minimal thermal conductivity with outstanding dimensional stability. Suitable for extreme temperature ranges, they are widely used in LNG facilities, ethylene plants, cold storage systems, and other low-temperature industrial applications.
Typical PIR Insulation System Structure
PIR insulation system structure diagram
  • PIR Shell: Inner layer + middle layer (if required) + 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, or GRP
  • Sealant: HS-10-02, Foster 95-50, etc.
  • Strapping Material: Stainless steel tape, sub sensitive tape
Packaging & Storage
  • Store in dry, shaded, well-ventilated areas away from heat sources and direct sunlight
  • Inner packaging: Black polyethylene bags; Outer packaging: Protective cartons
Handling Instructions
  • Handle PIR materials gently - avoid rolling, collisions, or heavy pressure during transport
  • Secure pipe and equipment insulation with glass fiber tape or steel bands
  • Use saws for precise cutting during installation
