  • Rubmix 20 is made from chloroprene rubber and offers good oil resistance. It has a working temperature range from -30 to 90 degrees C.
  • Rubmix 40 is made from EPDM-silicone. This material features high temperature resistance, as it can be used in temperatures up to 120 degrees C.
  • Rubmix 50 is made from polyurethane rubber. It has a working temperature range of -35 to 90 degrees C. Elements made with this material have a maximum oscillation angle of plus or minus 20 degrees, and limited oscillation frequencies.
