Silicone for automotive


Silicone for Automotive Sealing & Protection 

Silicone rubber delivers the strength, resistance and durability needed in automotive applications. 

As consumers demand an increase in power and performance, the increase of heat that is generated as a result is a factor that engineers have to consider and manage. Automotive manufacturers rely heavily on the quality and performance of rubber materials and with increasing heat present in new vehicles, silicone rubber comes into its own.

Due to the temperature rise, there has been an increase in silicone usage being used in new vehicles as EPDM gets replaced due to its inferior temperature performance (140°C max). 

With high temperature resistance from 230°C to -60°C and outstanding weathering properties, silicone rubber can extend the service life of automotive assemblies. Its resistance to rain, wind, salt, abrasion, ultraviolet radiation and chemicals make silicone the material of choice in the automotive sector.

Automotive Applications

Silicone rubber is used in a wide range of car parts including:

  • EV Battery Seals
  • Airbags
  • Engine gaskets
  • Headlamps
  • Ignition cables
  • HT Cables
  • Grommets
  • Radiator seals
  • Performance hoses
  • Vibration dampening
  • Shock absorbers
  • Spark plug boots
  • Ventilation flaps

As well as being used on vehicle exteriors, silicone automotive products are also used in the interior providing cushioning, load bearing, vibration suppression and protective shock absorption qualities to car seats and dashboards  - enhancing the comfort and driving experience.

Silicone Engineering's automotive parts have gone on to be used by a number of the car manufacturing giants including BMW, Volkswagen and Ford. Our high quality materials and our 55+ years manufacturing silicone rubber, give automotive manufacturers the guarantee that they are dealing with the silicone experts.
