General Automotive Parts

Even though they’re not usually visible, WACKER silicones have made a name for themselves as a high-quality, reliable material in the automotive industry. This is largely due to their versatile property profile which covers a universal range of applications. WACKER silicones are found under the hood, in the drive train, in electrical and electronics systems, in the interior or along the bodywork seams, where they protect components from aggressive media at high temperatures, seal, damp, conduct or insulate. All this is possible because the property profile of silicone as a base material is so fascinatingly flexible.

Benefits:

  • Excellent insulation
  • High heat resistance
  • Long service life
