product description
PUR insulation boards are a modern thermal insulation solution, characterized by a high closed-cell structure and minimal water absorption. They are mainly manufactured from polyether/polyester and isocyanate, along with essential additives such as flame retardants, stabilizers, and foaming agents. During the foaming reaction, gases are trapped within the closed cells, enabling PUR boards to achieve self-extinguishing properties. Thanks to these advantages, PUR Insulation Boards are widely used in low-temperature insulation applications.

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
