What requirements does material of mechanical hydraulic seal need？

Update:2017-05-10

    Different sealing materials will affect directly on the working environment,such as temperature, pressure, medium and ways of operation.DSH Seals tells you what requirements does material of mechanical hydraulic seal need.

1. Possess mechanical properties, such as tensile strength and elongation.

2. Appropriate elasticity and hardness, permanent compression and low deformation rate.

3. Resistance to high temperature and low temperature, not resolve and soften under high temperature and not stiffen under low temperature.

4. To accommodate with working medium，not swelling, resolve and stiffen etc.

5. Resistance of oxygen and aging and long life service.

6. Wearing resistance and not abrade metal.

7. Easy to be mold and secondary operation, must be low-cost,high-performance products.
