Comparison of O-Ring Materials

While selecting an O-ring for your application, a great deal of significance ought to be set on the material of the seal being utilized. Since an appropriate fixing activity is exceptionally reliant on the state of your O-ring, it is vital that an O-ring material be bested suit the working environment of your application. A portion of the regular materials used to make O-rings are nitrile elastic or Buna-N, Viton(r), silicone elastic, neoprene, and PTFE or Teflon(r).

Picking an O-ring material is reliant on various diverse components, yet two of the most basic variables are the working temperature go that O-rings are subjected to and the distinctive chemicals they might be presented to. Some extra components that assume a part in the determination of an O-ring material incorporate imperviousness to tearing and scraped spot, and daylight or maturing. Since most O-ring materials respond distinctively to various situations and in addition chemicals, every material has its own particular focal points and detriments.

Silicone rubbers are a gathering of elastomeric polymers delivered from silicon, hydrogen, oxygen, and carbon. Silicones for the most part have poor imperviousness to scraped area and tearing, and in addition low rigidity in addition to high co-productive of grinding - highlights that make them unsatisfactory for element fixing applications. Be that as it may, its outstanding imperviousness to outrageous temperatures, running from as low as - 150 degrees F to as high as +500 degrees F, makes it perfect for applications where seals are presented to high dry warms, as in car segments and cookware.
