Materials for FEP O-ring

The main materials used to make our FEP O-ring are Viton and silicone which are ideal for long-life service in sealing applications. FEP O-ring offers a lot of capabilities which is prepared to a standard temperature below 205◦C. FEP polymer is an extremely low coefficient of friction and very permeability to gases. The Viton material is a fluoropolymer elastomer and synthetic rubber which is very good for FEP O-ring with a chemical-resistant gloves and molded goods. Silicone is a synthetic class material with a chemical structure based on chains. Meaning it is typically resistant to chemical attacks.

FEP O-ring Quality and Standard Manufacturing

The FEP O-ring is consist of a uniform and seamless Teflon which encloses completely the core materials of silicone or Viton. We used the molding process to make the quality of the FEP O-ring before it goes to the markets and for the business owners.
