Silicones for Automotive Applications

How are silicones used in Automotive applications?

As automotive electronic applications continue to grow in number and complexity the demands made upon them for increased performance and reliability present many design challenges.  By nature, the environmental conditions under which these units must work are very harsh. Temperatures under the bonnet are increasing and geographical locations can also produce extremes in the other direction - these extreme thermal cycles induce stress and the possibility of component failure.

Another source of mechanical stress is a direct result of vibration derived from the engine and road conditions.  Chemical and oil attack are also common in and around the engine compartment, with water and humidity a constant threat. All these factors make component protection a high priority for any electronic design engineer working within the automotive industry.

The sealing of the powertrain, water and fuel systems require strong, flexible, temperature and fuel resistant sealants.  In many cases, traditional pre-cut gaskets have been replaced using FIPG (Formed in Place Gaskets) which offer overall cost reductions during the manufacturing process.

Silicones for Electric Vehicles

Electric Vehicle EV SiliconesSilicone chemistry is widely used within current automotive applications due to its inherent physical properties including, a wide operating temperature range, electrical insulation, high dielectric strength, low coefficient of thermal expansion and resistance to moisture and chemicals.

Advances in Electric & Hybrid Vehicle design continue to reduce component size and increase power output, resulting in an ever-increasing demand for greater protection and better heat dissipation to maintain performance and life span. New filler technologies combined with formulating techniques enable CHT to increase thermal conductivity across a range of silicone materials including, adhesives, gap fillers, encapsulants, greases and gels.

 

For more information about our thermal transfer materials, download our CHT SILCOTHERM brochure.

Silicones can provide:

  • More efficient heat dissipation
  • Increases in thermal conductivity
  • Effective bonding and sealing
  • Electrical insulation
  • Protection from moisture and chemicals
  • Protection from thermal stress, vibration and mechanical shock

Within the design of electric vehicles, silicones are providing engineering and manufacturing solutions for use in charging units, inverters, electric motors, battery packs, wiring, connectors, sensors, displays and control units.
