Available Compounds

  • NBR Rubber

    NBR is suitable for sealing gaskets that require oil resistance, abrasion resistance, and general industrial sealing performance.

    Oil Resistant Abrasion Resistant General Use
  • EPDM Rubber

    EPDM is commonly used for rubber gaskets exposed to weather, ozone, aging, moisture, or water-based environments.

    Weather Resistant Ozone Resistant Moisture Resistant
  • FKM Rubber

    FKM is used for high-performance sealing gaskets requiring strong resistance to heat, chemicals, oils, and fuels.

    Chemical Resistant High Temperature Premium Grade
  • HNBR Rubber

    HNBR provides improved heat, oil, and wear resistance compared with standard nitrile rubber, making it suitable for demanding automotive and industrial sealing applications.

    Heat Resistant Oil Resistant Durable
  • Silicone Rubber

    Silicone rubber offers excellent flexibility and temperature resistance. FDA or NSF compliant grades can be selected when required.

    Flexible Temperature Resistant FDA Available
  • Fluorosilicone Rubber

    Fluorosilicone combines low-temperature flexibility with improved fuel and oil resistance for specialty gasket applications.

    Fuel Resistant Low Temperature Specialty Compound
  • Neoprene Rubber

    Neoprene provides balanced resistance to weathering, abrasion, and mild chemicals, suitable for general-purpose molded rubber gaskets.

    Weather Resistant Abrasion Resistant General Purpose
  • SBR Rubber

    SBR is a cost-effective rubber material with good abrasion resistance, suitable for standard sealing and protective gasket applications.

    Cost-Effective Abrasion Resistant Standard Use
  • ACM / AEM Rubber

    ACM and AEM are suitable for automotive and industrial environments requiring heat and oil resistance.

    Automotive Use Heat Resistant Oil Resistant
