products - rubber packing sheets

  1. Application
    for production of gaskets and seals working statically in non-stretched status
  2. Types of rubber sheets
    • SBR - for normal conditions and neutral water solutions,
    • NBR - resistant against oils, fuels and fats,
    • CR - higher resistance against atmospheric conditions and weak acids,
    • EPDM - resistant against oxide, ozone, higher temperature and UV-radiation,
    • SBR/AA - resistant against abrasion and tear-off
    • NRL - for contact with food
  3. Versions
    • without textile plies,
    • with 1 or 2 textile plies, strengthening the resistance against tear-off
    • plain on front and bottom surface,
    • with cloth-print on bottom surface
  4. Standard dimensions

    Production of rubber sheets in dimensions and tolerances other than standard ones, is possible upon prior agreement.
