Insulation engineering solutions
PIR polyisocyanurate foam is a foamed material made by reacting isocyanate with polyether after the action of a catalyst. Its physical fire resistance is better than ordinary polyurethane foaming materials. It has the advantages of low thermal conductivity, wide operating temperature range, excellent dimensional stability, free cutting of tubes and plates according to customer requirements, etc. The product conforms to ASTM C591 and CINI 2.7.01 standards.

Comply with "Specifications for Thermal Insulation Materials for Covering Austenitic Stainless Steel"
It is an ideal organic low-temperature thermal insulation material with low thermal conductivity, light weight, shockproof, and strong adaptability. It is widely used in thermal insulation of oil refineries, chemical plants, ethylene, fertilizers, cold storage and LNG installations.
(1) It should be placed in a waterproof, moisture-proof, light-proof, dry, cool and ventilated place, avoid heat sources and strictly prevent exposure to the sun;
(2) The inner packaging is packed in black polyethylene bags, and the outer packaging is in cardboard boxes.
(1) The polyisocyanurate must be handled with care during transportation, and must not roll, hit, or bear heavy objects.
(2) Use glass fiber tape or steel tape for the insulation of pipes and equipment.
(3) The parts that need to be cut during the construction process can be processed with a saw blade.
