Key points for oil seal leakage inspection

Rubber seals are usually in a compressed state. Due to the viscoelasticity of rubber materials, the pressure will decrease with time, which is manifested as relaxation of compressive stress;

As EPDM belongs to polyene (PA66) hydrocarbon family, it has excellent vulcanization characteristics. Among all rubbers, EPDM has the lowest specific gravity. It can

NBR is widely used to manufacture various oil resistant rubber products because of its excellent oil resistance and physical and mechanical properties, such as 0-ring, rubber ring, hose

In addition to excellent chemical resistance and heat resistance, the product has homogeneity, and the surface has no problems such as penetration, cracking and pinholes.

Silicone rubber industry has made remarkable achievements. With the leap forward growth of consumption, silicone rubber industry has begun to change from high-performance special rubb
