product description
PIR insulation panels are made from polyisocyanurate foam, produced through the catalytic reaction of isocyanate and polyether. Compared to traditional polyurethane foam, PIR panels deliver superior fire resistance, lower thermal conductivity, a broad operating temperature range, and excellent dimensional stability. They are also lightweight, easy to cut, and adaptable to different project needs, meeting ASTM C591 and CINI 2.7.01 standards.
Thanks to these outstanding properties, PIR Insulation Panels are widely applied in cryogenic insulation systems, including oil refineries, chemical plants, ethylene facilities, fertilizer production, cold storage, and LNG installations.

Product Application
It is a kind of ideal organic thermal insulation materials applied at low temperature, result from its low thermal conductivity, lightweight, anti-vibration and compatibility. It is widely used as insulation in oil refinery, chemical, ethylene and fertilizer industries, as well as refrigeration house and LNG systems.
Packing and Storage
(1) Store in a dry, lightproof, shady, and ventilated place, keep away from heat source and protect from sun exposure.
(2) Inner Packing: Polythene bags Outer Packing: Cartons
Application and 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.
