Polyisocyanurate (PIR) is one of the most efficient insulation material used in construction. This product is an improvement of 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. Its physical and fire resistance is better than that of polyurethane. It has the advantages of small thermal conductivity and high dimensional stability, and it belongs to organic hard thermal insulation material.

Features


1. Fire resistance rated as B1;
2. Operating temperature range-196℃-120℃;
3. Excellent dimension stability;
4. Can be cut in panels and pipes according to customer requirement.

Application

It is a kind of ideal organic low-temperature heat insulation materials, which has the advantages of small thermal conductivity and high dimensional stability. It is suitable for a wide range of temperatures and is widely used in LNG, ethylene, cold storage and other low-temperature industries.

Typical PIR Insulation System Structure

PH 5.5-7 PIR Pipe Insulation High Durability Excellent Dimension Stability

(1) PIR Shell : inner layer + middle layer (if necessary) + outer layer;
(2) Secondary Vapor Barrier : PAP aluminum foil;
(3) Main Vapor Barrier : mastic + fiberglass meshes + mastic;
(4) Metal Protective Layer : aluminum alloy plate, stainless steel plate, aluminized steel plate, GRP;
(5) Sealant : HS-10-02, Foster 95-50, etc;
(6) Strapping Material : stainless steel tape, sub sensitive tape.

Packing and Storage

1. Store in a dry, lightproof, shady, and ventilated place, keep away from heat source and protect from sun exposure.

2. The inner package is packed in black polyethylene bags and the outer package is packed in cartons.

Cautions

1. PIR shall be handled gently, avoid rolling, collision and heavy pressure during moving.

2. When applied to pipe and equipment insulation, PIR shall be fastened with glass fiber tape or steel band.

3. Cut it with saw during application.
