High temperature resistant fluororubber O-ring black oil resistant nitrile rubber EPDM wear-resistant and pressure resistant sealing ring

  High temperature resistant fluororubber O-ring black oil resistant nitrile rubber EPDM wear-resistant and pressure resistant seal
EPDM is the English name of EPDM, which is abbreviated as EP
The common color of EPDM is black, which can also be made into any impassable color
As long as you provide color number or sample, volding company can produce it for you
The main chain of EPDM is a fully saturated straight chain structure without double bond, and there is diene Jing on its side chain, so it can be vulcanized with sulfur
EPDM has excellent aging resistance, ozone resistance, weather resistance, heat resistance (long-term use at 120 ℃), chemical resistance (such as alcohol, acid, strong alkali and oxidant), but it is not resistant to the corrosion of aliphatic and aromatic solvents
EPDM has low density in rubber and high filling characteristics, but it lacks self-adhesive and mutual adhesive
In addition, EPDM has outstanding steam resistance and can be used to make sealing products such as steam resistant diaphragm
EPDM has been widely used in washing machines, TV accessories and door and window sealing products, or in the production of rubber strips with various composite profiles

EPDM EPDM is polymerized from ethylene, propylene and non conjugated dienes
The main polymer chain of EPDM EPDM is completely saturated, which makes the EPDM EPDM EPDM O-ring resistant to heat, light, oxygen, etc
, especially ozone
2 / characteristics of EPDM O-ring, epdmo sealing ring and EPDM O-ring:
1 EPDM EPDM O-ring has extraordinary oxidation resistance, ozone resistance and erosion resistance;
2 EPDM three yuan ethylene propylene O ring has excellent anti-aging ability and has been praised as non cracking rubber

3 EPDM O-ring has good elasticity and compression deformation resistance;
4
EPDM sealing ring has low density and high filling;
5 because EPDM EPDM O-ring is essentially nonpolar, EPDM EPDM O-ring has strong resistance to polar solutions and chemicals and good insulation characteristics, but poor water tightness

In terms of chemical acid-base corrosion resistance, fluororubber or EPDM O-ring is generally used
In short, the difference between the two is that fluororubber has wider chemical resistance, fluororubber has higher temperature resistance, which can reach 240 degrees, while EPDM O-ring can only reach 150 degrees
Fluororubber can resist oil accumulation medium, while EPDM cannot
EPDM has the advantage of low price and is mostly used in sewage treatment or other water treatment products
