Our huge range of products also includes a wide array of Silicon Encapsulated O Rings. These products are quite popular with our huge client base. Elastomeric, rubber O-rings suffer from high friction and limited resistance to aggressive chemicals and gas permeation. Solid Teflon O-rings are rigid with no effective memory and high compression set. INVENTRO’S Teflon Encapsulated O-rings combine the resilience and sealing force of an elastomer with the chemical resistance of Teflon.This is accomplished by the use of an elastomeric core of silicone or Viton, with a relatively thin encapsulation of Teflon 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 uasge in hostile environments.
