Product introduction

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.

Technical Properties

Typical PIR Insulation System Structure

(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.
