Product Introduction

Polyisocyanurate (PIR) is a foaming material made by the polymerization of isocyanate and polyether. Its physical and fire resistance properties are superior to polyurethane. With advantages including small thermal conductivity and high dimensional stability, it belongs to the category of organic hard thermal insulation materials.

Features

Fire resistance rated as B1
Operating temperature range: -196℃ to +120℃
Excellent dimensional stability
Can be custom-cut in panels and pipes according to customer requirements

Application

PIR is an ideal organic low-temperature heat insulation material with advantages of small thermal conductivity and high 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, away from heat sources and protected from sun exposure.
Inner package: black polyethylene bags; Outer package: cartons.

Cautions

Handle PIR gently, avoiding rolling, collision, and heavy pressure during movement.
When applied to pipe and equipment insulation, fasten PIR with glass fiber tape or steel band.
Cut with a saw during application.
