Product Description

Moisture Resistance CFC Free PIR Pipe Insulation Excellent Dimension Stability

Polyisocyanurate (PIR) is one of the most efficient insulation materials used in construction. This product represents an improvement over previously used PUR boards (polyurethane), typically produced as a foam and used as rigid thermal insulation.

Polyisocyanurate PIR is a foaming material made by the polymerization of isocyanate and polyether. It offers superior physical and fire resistance compared to polyurethane, with advantages including small thermal conductivity and high dimensional stability. It belongs to the category of organic hard thermal insulation materials.

Key Features

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

Applications

This product is an ideal organic low-temperature heat insulation material, featuring 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, keep away from heat source and protect from sun exposure.
The inner package is packed in black polyethylene bags and the outer package is packed in cartons.

Cautions

PIR shall be handled gently, avoid rolling, collision and heavy pressure during moving.
When applied to pipe and equipment insulation, PIR shall be fastened with glass fiber tape or steel band.
Cut it with saw during application.
