Production Description:

Chem- Ring Seal(PTFE- Coated ring) will be rubber elasticity and tightness and the Teflon chemical resistance combine organic, Which is a silicone or Viton rubber (fluoro rubber) system within the core and a relatively thin The Teflon FEP (poly- FEP) or Teflon PFA (soluble PTFE) coated with a combination of the rubber seals Teflon has excellent sealing properties. Rubber O- Ring easy to wear, Chemical corrosion resistance and anti- Gas permeability is poor, Pure Telfon O- Ring hardness, High resistance to compression, But less flexible. Coated Teflon FEP / Teflon PFA O- Ring has a good resistance to swelling and chemical stability (except at high temperatures by the alkali metals, Fluorine and some halides erosion) near the rubber O- Ring in the vicinity have a good flexibility , Telfon FEP / Teflon PFA friction coefficient is very small (only 0. 1 ~ 0. 2), But also has excellent resistance to gas permeability, These properties make Chem- Ring seals can really apply to harsh environments.
PTFE- Coated O- Ring to replace the expensive perfluorinated rubber O- Ring.
