Rubber extrusion products: EPDM rubber flexible joint

EPDM (EPDM) rubber is great at ant-acid and anti-Alkali, also has corrosion resistance, high-temperature resistance. The EPDM rubber joint is a rubber joint with high comprehensive performance. The so-called comprehensive performance is good, the materials used in the production and the special production technology. The choice of materials is a special EPDM rubber, this kind of rubber has the characteristics of high-temperature resistance, wear-resistance, and corrosion resistance.

 

Regarding the manufacturing of the rubber joint, it is known that the combination of layers of rubber and cord cloth, made from the combination of corrosion-resistant and wear-resistant rubber, won't be affected by the transmission medium.

 

The layer of rubber made by combining a curtain cloth with an EPDM rubber, which not only acts as a binding but also protects the spherical part.

The vulcanization time is insufficient, each kind of material has a satisfied vulcanization time to be able to vulcanize completely, the same material formula different vulcanization time also will be different, does not vulcanize completely, does not achieve the material actual performance, such physical properties will be relatively poor, such as aging resistance, tear-resistance and tensile properties.

 

The corrosion of rubber flexible joints is usually understood as the damage to the metal material of rubber flexible joints under the action of chemical or electrochemical environment. As corrosion occurs in the spontaneous interaction between metal and its surroundings, how to separate metal from its surroundings or to use more non-metallic synthetic materials has become a problem of general concern. It is well known that the corrosion damage of metal has a great influence on the working life, reliability, and service life of rubber soft joints.
