Rubber seals in the sealing device can be dust-proof waterproof anti-impurities, to ensure the sealing device sealing. Sealing a large part of the market is the use of EPDM renewable rubber production, which has EPDM rubber, good resistance to high and low, anti-aging, high insulation, anti-corrosion properties, both for the production of sealing products Ensure product quality, but also significantly reduce the cost of raw materials.
The use of EPDM reclaimed rubber production seals, reclaimed rubber selection on the quality of the seal played a decisive role, it should follow the following principles:
1, EPDM reclaimed rubber tensile strength, tensile stress, tensile elongation as high as possible, it is because the higher these physical indicators, the seal produced by the better sealing performance;
2, the production of seals with EPDM reclaimed rubber hardness as high as possible, under normal circumstances, the high hardness of EPDM reclaimed rubber seal than the low hardness of EPDM reclaimed rubber seal seals Good effect, high wear resistance;
3, the seal work has been in a compressed state, it is through the deformation of the compression cross-section of the stress, and the contact surface in close contact with play a sealing effect, the seal compressive stress will increase with the use of time decreases, Appear stress relaxation, so the better compression performance of EPDM reclaimed rubber, the better seal sealing effect, the longer service life;
4, EPDM reclaimed rubber aging resistance as strong as possible, you can extend the life of seal products;
5, high temperature will accelerate the aging of seals, so the higher temperature of EPDM rubber is better.
In summary, the higher the general content of plastic composite EPDM reclaimed rubber the higher the index, the replacement of EPDM seal production seal the better, longer service life.
