  • standard hardnesses 25 ShA – 70 ShA
  • recyclable
  • wide range of colours, easy to customize
  • service temperature range -40 - + 100°C
  • EMC grades with attenuation of 40 dB – 100 dB
  • FDA approved grades available


TPU (Thermoplastic Urethane)

  • good resistance to weathering, ozone and UV exposure
  • good abrasive properties
  • limited resistance for oils (resists oils as splash)
  • standard hardnesses 50 ShA – 70 ShA
  • recyclable
  • wide range of colours, easy to customize
  • service temperature range -40 - + 100°C
  • FDA approved grades available


TPV (Thermoplastic Vulcanizate)

  • show excellent resistance to UV Light, very little change in Delta E
  • improved oil and chemical resistance, Exhibit superior chemical resistance over a wide range of temperature (Oils / Petroleum and Sebum, Automotive fluids, aqueous solutions, acids and bases, organic solvents)
  • flame retardant grades 50 ShA to 50 ShD , UL 94 V-0 ; 1.5mm
  • hardness range 15 ShA to 50 ShD Temperature range continues use up to 125°C and short-term exposure up to 150°C. Brittle point lower than -60°C for most grades. Provides good low-temperature flexibility and impact toughness
  • it looks and feels like thermoset rubber
  • improved compression set at elevated temperatures (over 70°C)
  • medical/food contact grades from 45 ShA to 50 ShD


EPDM (Ethylene Propylene Diene Monomer)

  • superior resistance to weathering, ozone and UV exposure
  • provides excellent chemical resistance, and good electrical properties
  • resists animal and vegetable oils, steam, water and oxygenated solvents
  • flame retardant grades UL 94 V-2 (test thickness < 3,0 mm)
  • standard hardnesses 40 ShA – 70 ShA
  • limited range of colours
  • working temperature range -40 - + 120°C
  • EMC grades with attenuation of 40 dB – 60 dB


NBR (Nitrile Butadiene Rubber)

  • limited weathering resistance
  • it is generally resistant to fuel and other chemicals. Also resistant to aliphatic hydrocarbons but less resistant aromatic hydrocarbons, ketones, esters, aldehydes and to ozone
  • flame resistance is poor
  • hardness range 20 - 95 ShA
  • Working temperature range of – 40 to + 125°C
  • environmental performances: colorability, gas permeability and water resistance are excellent
  • other physical & mechanical properties: adhesion to metal and rigid materials are excellent, abrasion resistance, compression set and tear resistance are good to excellent


CR (Chloroprene Rubber)

  • good weathering resistance, flame retarding. Moderate resistance to petroleum-based fluids
  • service temperature -45….+120°C
  • adhesion to many substrates
  • good resistance toward chemicals and ageing
  • CR in general has good chemical stability and maintains flexibility over a wide temperature range
  • hardness range 40 – 95 ShA


Q (Silicone)

  • excellent resistance to weathering, ozone and UV exposure
  • also provides excellent chemical resistance and good electrical properties
  • resists oils as splash
  • flame retardant grades UL 94 V-0 (test thickness < 0,8 mm), halogen free
  • standard hardnesses 25 ShA – 90 ShA
  • wide range of colours, easy to customize
  • service temperature range -50 - + 200°C
  • EMC grades with attenuation of 40 dB – 120 dB
