Polyurethane foam is made of polymerized foamed isocyanate and hydroxy compound. According to its hardness, it can be divided into soft and hard, of which soft is the main variety. In general, it has excellent elasticity, flexibility, elongation and compressive strength; good chemical stability, resistance to many solvents and oils; excellent wear resistance, 20 times larger than natural sponges; and excellent processing Properties such as sex, heat insulation and adhesion. Emerging economies China and India are major consumers of polyurethane foam and are characterized by ample supply of raw materials and rapid expansion.
Application of polyurethane in coatings
Polyurethane technology started in Germany. In 1937, Mr. Otto Bayer invented polyurethane, which laid the foundation for polyurethane chemistry and developed polyurethane technology suitable for different applications. Since 1955, Bayer has applied various monomeric and polymeric isocyanates, polyesters, polyethers and acrylates to the production of polyurethane coatings. In 1965, the anti-fading two-component polyurethane coating was applied to aircraft and train fuselage; Bayhydrol® was used as an aqueous film-forming material in 1987; Bayhydur® and Bayhydrol® were put into use as an aqueous two-component polyurethane system in 1994. Polyurethane coatings dominate the wood coatings industry, accounting for 75% of the market, followe
