PU polyurethane sealing ring Polyurethane has very good mechanical properties, wear resistance and high pressure resistance are far superior to rubber, aging resistance, ozone resistance and oil resistance are quite good. The disadvantage of PU polyurethane sealing ring is that it is easy to be hydrolyzed at high temperature. It is generally used in the sealing link of high pressure resistance and wear resistance. PU polyurethane sealing ring is widely used in the hydraulic industry, and the general operating temperature range is before -45℃/+90℃
Tianran rubber Seals have good wear resistance and elastic tensile strength. However, it is easy to age in the air, softens when heated, resistant to alkali but not strong acid, easy to expand and dissolve in mineral oil or gasoline, and has excellent shock absorption performance. Tianran rubber seals are widely used in shock absorber materials, in addition to food and beverages, direct contact seals and non-hydraulic system seals, and the general operating temperature range is between -20°C/+100°C
