Polyurethane is a polymer compound, which is polymerized by multiple isocyanate groups and polyol groups. It has excellent mechanical properties, wear resistance, corrosion resistance, chemical resistance, insulation and various physical and chemical properties. Polyurethanes are commonly used to make foams, coatings, adhesives, elastomers, plastics, fibers and other industrial and consumer products. The properties of polyurethanes can be tuned by choosing different raw materials and processing conditions, making them suitable for various applications.
Polyurethane Foam Products
Polyurethane foaming is to mix polyurethane raw materials through special equipment, then react under certain temperature and pressure conditions to generate gas, and expand into foam materials with certain density and strength in a short time. Due to its good insulation performance, heat dissipation performance, sound absorption performance and other characteristics, it is widely used in construction, automobiles, home appliances, toys, medical equipment, aerospace and other fields.
Advantages of Polyurethane
Polyurethane is a multifunctional polymer material with the following advantages:
Good processability:
Polyurethane can be shaped by various processing methods, such as injection molding, extrusion, calendering, etc.
Excellent physical and mechanical properties: Polyurethane has relatively high strength, wear resistance and elasticity, and maintains good flexibility in low temperature environments.
