Rigid polyurethane foam (PUR) is an efficient low-temperature insulation material formed by polymerization reaction between polyether polyol and isocyanate as the main raw material.
Rigid polyurethane foam has the advantages of low thermal conductivity, high compressive strength, stable chemical properties, easy construction, etc. It is widely used in petrochemical industry, construction industry, food storage and other industries. When applied, it can be prefabricated into products such as boards or tubes and shells by factories, and can also be sprayed or filled with foam on site.

Bundled with packing tape, can be customized if there are special requirements.
It should be placed in a waterproof, moisture-proof, light-proof, dry, cool and ventilated place, avoiding heat sources and strictly preventing exposure to the sun.
Rigid polyurethane foam in the transportation and handling process, pay attention to be gently held and put, shall not roll, impact, shall not bear the pressure of heavy objects.
As pipeline, equipment insulation should be bundled with steel tape.
In the construction process, the parts that need to be cut and processed can be processed by saw blade.
