The advantages of imported polyurethane mainly include high strength, high wear resistance, excellent oil resistance and aging resistance, good elasticity, cold resistance and chemical resistance. These advantages enable the wide application of imported polyurethane in many fields.
First, the imported polyurethane has a high strength and excellent wear resistance. The wear resistance of polyurethane products is better than cyanide butadiene rubber and better than natural rubber and other synthetic rubber. In addition, polyurethane products have a wide range of hardness, from Shaw A10 to D80, and can have 400-800% elongation in such a hardness range, while natural rubber elongation of 550% higher hardness is Shaw A701.
Secondly, the imported polyurethane has good elasticity and cold resistance. Polyurethane products have good elasticity, excellent resilience, and can be used for dynamic joints. Meanwhile, polyurethane has good cold resistance and can maintain good performance in low temperature environment 2.
In addition, the imported polyurethane also has excellent oil resistance and aging resistance. The oil resistance of polyurethane products is better than that of cyanide butadiene rubber, and the aging resistance is better than that of natural rubber and other synthetic rubber. At the same time, polyurethane products also have the corrosion resistance to hydrolysis and acid and alkali solutions 1.
