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 PU polyurethane sealing ring in the sealing link is widely used in the hydraulic industry, and the general operating temperature range is between -45°C/+90°C.
Tianran rubber seals have good wear resistance, elastic tensile strength, but are easy to age in the air, soften when exposed to heat, alkali-resistant but not strong acid, easy to expand and dissolve in mineral oil or gasoline, and shock-absorbing properties Excellent.
Tianran rubber seals are widely used in shock absorber materials, in addition to food and beverages, direct contact seals and non-hydraulic system seals. The general operating temperature range is between -20°C/+100°C.
