Polyisocyanurate (PIR) is a foaming material created through the polymerization of isocyanate and polyether. With superior physical and fire resistance properties compared to polyurethane, PIR offers excellent thermal insulation with minimal conductivity and outstanding dimensional stability, making it an ideal organic rigid insulation material.

• B1 fire resistance rating
• Operating temperature range: -196℃ to +120℃
• Exceptional dimensional stability
• Customizable as panels or pipes to meet specific requirements

As an ideal organic low-temperature insulation material with minimal thermal conductivity and excellent dimensional stability, PIR foam is widely used in LNG, ethylene production, cold storage, and other low-temperature industrial applications.

• 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, stainless steel, aluminized steel, or GRP
• Sealant: HS-10-02, Foster 95-50, etc.
• Strapping Material: stainless steel tape or sub sensitive tape

• Store in dry, shaded, well-ventilated areas away from heat sources and direct sunlight
• Inner packaging: black polyethylene bags; Outer packaging: cartons

• Handle gently to avoid rolling, collisions, or heavy pressure during transport
• Secure with glass fiber tape or steel bands when insulating pipes and equipment
• Use saws for cutting during installation
