Polyurethane (PUR) is a kind of polymer containing more carbamate groups in the main chain. It is a kind of polymer material between plastics and rubber. It has large elongation, wide hardness range, wide formula adjustment range, excellent wear resistance and mechanical properties. The pouring polyurethane elastomer (CPUR) is the most important one of the three types of polyurethane elastomer processing. Its dosage accounts for 6o% of PUR. It has the advantages of diversified chemical structure, easy viscosity adjustment, excellent processing technology, easy to put into industrial production, easy to use and fast curing, so it is very suitable for large production. Complex components. Polyurethane wear-resistant liner is produced by casting polyurethane elastomer process. Polyurethane is a kind of polymer containing urethane-type repetitive units in the macromolecular chain. It is called polyamino acid ester. It is also called polyurethane in English, PU or PUR for short. PU is a product of polyisocyanate and polyether or polyester polyols in a certain proportion.

      Blessed B1 polyurethane insulation board is made of polyether polyol, polyether polyol industrial products; isocyanate, curing agent, flame retardant additives, antistatic additives, pigments, reinforcement materials. It is formed by injection molding after reacting in a reactor, and has the characteristics of flame retardancy, heat insulation, low thermal conductivity and easy construction.
      With the continuous development and improvement of industry, Blessed B1 polyurethane insulation board has been applied to automobile production, mining, port, grain and food processing, medical and health care, construction machinery, electronic equipment, construction, furniture, textile and clothing shoes, synthetic leather, water conservancy, petrochemical, printing and packaging, Sports Fitness and other industries have a large number of applications.
