Product Description

Polyisocyanurate PIR Pipe Insulation - Durable Good Flammability Resistance

Application

Polyisocyanurate (PIR) is an ideal organic low-temperature thermal 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.

PIR is a foaming material made by polymerizing isocyanate and polyether, offering superior physical and fire resistance compared to polyurethane. This organic rigid thermal insulation material combines low thermal conductivity with outstanding dimensional stability.

Key Features

Fire resistance rated B1
Operating temperature range: -196°C to +120°C
Excellent dimensional stability
Customizable cutting in panels and pipes to meet specific requirements

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, away from heat sources and protected from sun exposure
Inner package: black polyethylene bags; Outer package: cartons

Cautions

Handle PIR gently - avoid rolling, collision, and heavy pressure during movement
When applied to pipe and equipment insulation, fasten PIR with glass fiber tape or steel band
Use a saw for cutting during application
