SEMICOSIL®

SEMICOSIL® is WACKER's brand name for its silicone rubber grades developed for use in electronics applications. Each product is customized to the requirements of a specific application, resulting in a portfolio of highly specialized grades.

We offer silicone rubbers with:

  • Extremely high chemical purity (ion content of < 2 ppm)
  • Low-temperature stability (down to −120 °C)
  • High temperature stability (up to +210 °C)
  • Resistance to aggressive media, e.g., fuels and acidic exhaust

SEMICOSIL® silicones are available as 1- and 2-part silicone rubber grades, addition-cured or UV-cured. The curing system and time can be adjusted individually by choosing the appropriate catalyst. All grades are fully automatically processable in mixing and metering units and ideal for processing by conventional methods or in mass production.
