J-Flex and SENY Ltd – your complete source for speciality sheet products including Viton® Sponge Rubber Sheetings



   J-Flex and SENY Ltd enjoy an industry wide reputation as the market leader for speciality sheet rubber products. This means bringing a wide offering to the market, not just the commodity items BUT also the really special grades such as Viton® Sponge Rubber Sheets.


   J-Flex Viton® Sponge is a closed cell formulation that is manufactured with a continuous skin on both sides. The skin makes the sheet stronger and more tear resistant and even when the surface skin is punctured or cut; the sheets will not allow the passage of air or fluid between cells. The non-absorbent sheets are highly compressible, resilient and lightweight and therefore provide good thermal insulation.

Like dense Viton®, J-Flex Viton® Sponge is generally resistant to:

  • Aliphatic and aromatic hydrocarbons
  • Oil
  • Fuels
  • Ozone and Weather
  • Lubricants
  • Animal and Vegetable Oils
  • Acids
  • Hot Water

   J-Flex Viton® Sponge sheets have a service temperature of -25°C to 204°C; although elevated temperatures while under compression will have an adverse effect on the resilience of this material.
