Product Description

Flame Resistant PIR Pipe Insulation - Easy Cutting with Good Thermal Stability

Kaff Rees provides professional insulation solutions from -196℃ to +400℃, specializing in R&D, production, and distribution of insulation materials and pipe support systems. Our comprehensive product portfolio covers all support situations, operational loads, and temperature ranges for industrial insulation systems in petrochemical, coal chemical, LNG, low temperature, cold air, subway, and other construction applications.

Polyisocyanurate (PIR) is a foaming material made by polymerizing isocyanate and polyether. With superior physical and fire resistance properties compared to polyurethane, PIR offers excellent thermal conductivity and dimensional stability, making it an ideal organic hard thermal insulation material.

Key Features

Fire resistance rated as B1
Operating temperature range: -196℃ to +120℃

Applications

PIR is an ideal organic low-temperature heat insulation material with excellent thermal conductivity and dimensional stability. Suitable for a wide temperature range, it is widely used in LNG, ethylene, cold storage, and other low-temperature industries.

Typical PIR Insulation System Structure

PIR Shell: inner layer + middle layer (if necessary) + 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, GRP
Sealant: HS-10-02, Foster 95-50, etc
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 - avoid rolling, collision, and heavy pressure during movement
When applying to pipe and equipment insulation, fasten with glass fiber tape or steel band
Use a saw for cutting during application
