Polyurethane (PU) refers to the molecular structure containing urethane groups (-NHCOO-) a class of polymers, depending on changes in the composition of its performance from soft to hard within a wide range, it products to foam (soft, semi-hard and hard), followed by the coatings, adhesives, elastomers, such as sheet metal.
PU elastomer products can be divided into seven categories: (1) wear-resistant, self-lubricating PU elastomer category; (2) ultra-high rebound PU elastomer category; (3) high shock absorption PU elastomer category; (4 ) slow rebound, absorbing PU elastomer category; (5) high temperature 130 degrees -150 degrees, burning smoke PU elastomer category; (6) high hardness 96D ± 2DPU elastomer category; (7) special antistatic PU elastomer category.
Polyurethane materials, use very wide, can be used instead of rubber, plastics, nylon, etc., used in airports, hotels, construction materials, automobile plants, coal plants, cement plants, apartment, villa, landscaping, color stone arts, and parks.
