(EPDM) can be widely used in drinking water treatment, sewage treatment, other seals, and other occasions that do not contain oil. The performance of EPDM rubber itself is very superior, which is well reflected in high temperature resistance, wear resistance, corrosion resistance and so on. Its tensile deformation can reach more than 200%. But the disadvantage is that the oil can not be contacted, such as gasoline, diesel oil, hydraulic oil and so on can not be contacted. If the medium contains oily substances, the O-ring will expand or be eroded away.

EPDM EPDM rubber is made from the polymerization of ethylene, propylene and non-conjugated diolefin. The main polymer chains of EPDM EPDM are fully saturated, which makes the EPDM O-rings resistant to heat, light, oxygen, and especially ozone. 2/ EPDM rubber O-ring, EPDMO type sealing ring, EPDM O-ring characteristics:

1)EPDM ternary ethylene propylene O-ring has extraordinary oxidation resistance, ozone resistance and erosion resistance;

2) EPDM EPDM O-ring has excellent anti-aging ability and is praised as non-cracking rubber;

3) EPDM O-ring has good elasticity and compression resistance;

4)EPDM type sealing ring has low density and high filling;

5) Because EPDM EPDM O-ring is non-polar in nature, EPDM EPDM O-ring has strong resistance to polar solutions and chemicals and good insulation characteristics, but poor water density.

Usually in terms of chemical acid and alkali corrosion resistance using fluorine rubber or epdm type O sealing ring, in simple terms the difference between the two: fluorine rubber resistant to chemical energy more widely, fluorine rubber resistance temperature would be higher, can reach 240 degrees, and epdm rubber o-rings can reach 150 degrees, only can fluorine rubber oil resistant tired medium, and epdm can't. EPDM has the advantage of being less expensive and is often used in wastewater treatment and other water treatment products.

EPDM rubber English name EPDM EP. The common color of EPDM is black, and it can also be made into any different color. As long as you provide the color number or sample octave, the company can produce it for you. The main chain of EPDM is a completely saturated straight chain structure with no double bonds, and the side chain has dienoidins, which can be sulfurized with sulfur. EPDM has excellent aging resistance,

Ozone resistance, weather resistance, heat resistance (can be used at 120℃ for a long time), chemical resistance (such as alcohol, acid, strong alkali, oxidant), but not aliphatic and aromatic solvents. EPDM in rubber is low density and has high filling characteristics, but lack of self-adhesive and mutual adhesive. In addition, EPDM rubber has outstanding steam resistance, can make steam resistance diaphragm and other sealing products. EPDM has been widely used in washing machines, TV accessories and doors and Windows sealing products, or a variety of composite section in the production of rubber strips.
