High Reliability Polyisocyanurate Foam Pipe Insulation Good Flammability Resistance


Polyisocyanurate foam is typically used for metal faced panels, roof boards, cavity wall boards and pipe insulation. PIR foam panels laminated with pure embossed aluminium foil are used for fabrication of pre-insulated duct that is used for heating, ventilation and air conditioning systems. On the other hand, PIR cannot be used to insulate existing cavity walls, since there is no PIR foam that can be injected into existing cavity walls. It offers even better thermal stability and flammability resistance than polyurethane foam.


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

(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.
