Encapsulated O Rings - Ptfe Fep Polymer, Elastomeric Core | Chemical Resistant, Low Friction, High Sealing Capability

We are master in manufacturing and supplying massive array of Encapsulated O Rings in Mumbai, Maharashtra, India. Elastomeric, rubber O-rings suffer from high friction and limited resistance to aggressive chemicals and gas permeation. Solid PTFE O-rings are rigid with no effective memory and high compression set. Our range of PTFE Encapsulated O-rings combine the resilience and sealing force of an elastomer with the chemical resistance of PTFE. This is accomplished by the use of an elastomeric core of silicone or Viton, with a relatively thin encapsulation of PTFE FEP or PFA polymer. This produces an elastomeric PTFE seal with maximum sealing capability. FEP Encapsulated O-rings are solvent resistant and chemically inert (except for attack by alkaline metals, fluorine and some halogenated compounds at high temperatures) yet have an elastomeric memory near that of rubber O-rings. FEP polymer, also, has an extremely low coefficient of friction (.1 to .2) and very low permeability to gases, making CHEM-RINGS a virtually universal seal for use in hostile environments.
