Available Compounds

  • NBR (Nitrile)

    The workhorse for custom molded parts. Excellent resistance to petroleum-based oils, greases, and fuels. Best choice for industrial bushings, bumpers, and seals.

    –40°C to +120°COil Resistant Cost-Effective
  • FKM (Viton®)

    High-performance fluoroelastomer for extreme conditions. Exceptional chemical and heat resistance, perfect for aggressive environments in aerospace and chemical processing.

    –20°C to +200°C Chemical Resistant High Temp
  • Silicone (VMQ)

    Excellent thermal stability and dielectric properties. Ideally suited for medical, food-grade applications, and components requiring biocompatibility or extreme heat resistance.

    –40°C to +120°C Oil Resistant Cost-Effective
  • EPDM

    Superior outdoor performance. Highly resistant to ozone, UV radiation, and weathering. The go-to material for grommets, weather-stripping, and outdoor protective covers.

    –50°C to +150°C Weather Resistant Ozone Stable
  • Neoprene (CR)

    A versatile, balanced elastomer with good mechanical toughness. Offers moderate resistance to chemicals, oils, and weather, making it excellent for vibration damping and protective boots.

    –40°C to +100°C Tough & Resilient Balanced Performance
  • HNBR (Hydrogenated Nitrile)

    Combines the oil resistance of Nitrile with significantly improved thermal and mechanical properties. Essential for high-stress automotive and high-pressure sealing parts.

    –30°C to +160°C High Strength Abrasion Resistant
