product description
PUR insulation panels are an advanced type of thermal insulation material, featuring a high closed-cell content and very low water absorption. They are primarily produced from polyether/polyester and isocyanate, combined with additives such as flame retardants, stabilizers, and foaming agents. The gas generated during the foaming process fills the closed cells, giving PUR panels their self-extinguishing property. Due to these characteristics, PUR Insulation Panels are widely applied in low-temperature insulation systems.

Product Application
It is a low thermal conductivity, high strength, light weight, soundproofing, anti-vibration, isolating, floating, stable product, and easy to install. It’s wildly used in petroleum, chemical, ethylene industries, as well as in cold storage, refrigerators and buildings. PUR can be produced into different shape segments in workshop and it also can be foamed on site.
Packing and Storage
(1) Strapping Packing, special packing is available on request.
(2) Store in dry, ventilated place, keep away from light.
Application and Cautions
(1) Rigid PUR Foam shall be handled gently, and avoid rolling, collision and heavy pressure during moving.
(2) When applied to pipe and equipment insulation, fasten with steel bands.
(3) Cut it with saw during application
