The choice of sealing ring material is of great significance to its sealing performance and service life, and the performance of the material directly affects the performance of the sealing ring.
Polyurethane sealing ring has the characteristics of wear resistance, oil, acid and alkali, ozone, aging, low temperature, tearing, impact, etc. The polyurethane sealing ring has a large load bearing capacity and is widely used in various fields. Hydrolysis resistance, wear resistance, high strength, suitable for high pressure oil equipment, lifting equipment, forging machine tools, large hydraulic equipment, etc.
Polyurethane sealing ring: Polyurethane has very good mechanical properties, and its wear resistance and high pressure resistance are far superior to other rubbers. The aging resistance, ozone resistance and oil resistance are also quite good, but it is easy to be hydrolyzed at high temperature. Generally used for high-pressure, wear-resistant sealing links, such as hydraulic cylinders. The general operating temperature range is -45~90 ℃.
In addition to the general requirements for the material of the sealing ring, the polyurethane sealing ring should also pay attention to the following conditions:
(1) Rich in elasticity and resilience;
(2) Appropriate mechanical strength, including expansion strength, elongation and tear strength, etc.
(3) The performance is stable, not easy to swell in the medium, and the thermal shrinkage effect (Joule effect) is small.
(4) It is easy to process and form, and can maintain precise dimensions.
(5) Does not corrode the contact surface, does not pollute the medium, etc.
