Product Introduction

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.

Key Features

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

Applications

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.

Typical PIR Insulation System Structure

Low Thermal Conductivity Fire Resistant Polyisocyanurate Foam Pipe Insulation with High Dimensional Stability

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

Packing and Storage

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

Handling Cautions

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
