A great option for many industries are these peroxide cured EPDM o-rings. They're made from a special kind of rubber called synthetic elastomer. Very tough, this rubber point can withstand various chemicals and work at high and low temperatures. Probably the best part about these o-rings that they are very great at sealing. That means they can prevent liquids or gases from leaking out. Due to these characteristics, they are ideal for challenging roles where dependability is critical. Peroxide Cured EPDM O-Rings: Benefits and Why to get them from Shanghai Chongfu In This Text
The most common are peroxide cured EPDM o-rings in many factories and industries. You know them from several fields, like in making cars, in food processing, medical supplies, oil and gas and so on. These o-rings are perfect for applications that break down with other materials. It can fail (for example) if it is exposed to aggressive chemicals, very high temperature, extreme cold, etc. Peroxide cured EPDM o-rings are made for this exact kind of unforgiving environment, however. That's why many companies trust them to do the job correctly.
Why Peroxide Cured EPDM O-Rings Are Superior to Other Types of Rubber One of the primary reasons is their ability to withstand both extremely high and low temperatures. They are shape and strength stable from -50°C to 150°C. It can also resist ozone or UV light that can degrade other materials. They are also very resistant to various chemicals (acids, bases, etc.). Sure that the above properties give you the most suitable option for the harsh environment, where the other materials tend to fail.
Ethylene propylene diene monomer (EPDM) is a unique kind of rubber used to produce peroxide cured EPDM o-rings. This specific rubber has outstanding resistance to heat, ozone, and UV light. O-rings are further strengthened with a special peroxide curing process. This process adds a peroxide catalyst to the rubber during the manufacturing process. This strengthens the rubber and makes it even more resistant to chemicals. This process makes the o-rings stronger and better used.

Peroxide cured EPDM o-rings excel in sealing. There robust sealing capabilities allow then to perform for some tough jobs in a variety of industries. They are used in food manufacturing plants, where sanitation and safety are critically important. They are also applied in oil and gas industry where the equipment must work in harsh conditions. These o-rings are reliable sealing options, which make them suitable to function in the extreme conditions. To be able to rely on them to keep it under lock and key and functioning smoothly.”
