Polyisocyanurate PIR
Polyisocyanurate Foam (PIR) is a foam material made from polyether polyol and excess isocyanate by trimerization reaction, and its physical fire resistance is more excellent than that of polyurethane. It has the advantages of low thermal conductivity, wide temperature range, excellent dimensional stability, and free cutting of tubes and boards according to customers' requirements.
Polyisocyanurate is an ideal organic low-temperature heat-insulating material with the advantages of low thermal conductivity, lightweight and shockproof, and strong adaptability. It is widely used in oil refineries, chemical plants, ethylene, chemical fertilizers, cold storage and LNG device heat insulation.

It should be placed in a waterproof, moisture-proof, light-proof, dry, cool and ventilated place, avoiding heat sources and strictly preventing exposure to sunlight.
The inner package is packed in black polyethylene bag and the outer package is packed in carton box.
Polyisocyanurate should be handled gently during transportation and handling, and should not be tumbled, hit, or pressurized by heavy objects.
As pipeline and equipment insulation, it should be bundled with fiberglass tape or steel tape.
In the process of construction, the parts that need to be cut and processed can be processed by saw blade.
