Polyurethane material is the best performance thermal insulation material in the world.

A class of polymers with NHCOO - repeating structural units in the main chain. English

abbreviation PU. Polymerization of isocyanate (monomer) and hydroxyl compound.

Due to the strong polarity of the amino acid ester group, insoluble in non polar groups,

with good oil resistance, toughness, wear resistance, aging resistance and adhesion.

The materials can be adapted to a wide temperature range (- 50 to 150 degrees C)

with different raw materials, including elastomers, thermoplastic resins and thermosetting

resins. Not resistant to hydrolysis at high temperature, but also not resistant to alkaline media.
