In Automotive

Silicone is used in a variety of ways in the automobile industry. It is used in both automotive parts and in car care products.

Silicone in Automotive Parts

Consumers demand for more power and performance in their automobiles increases the amount of heat generated in engines.  Silicone rubber is used in the automotive industry because it delivers the strength, resistance and durability needed in high-performance automotive applications. Silicone products can be found under the hood, in the drive train, in electronics and electrical systems, in car interiors or at seams in the bodywork. Even working in intense heat, they protect against aggressive substances, or act as seals, vibration dampers, conductors or insulators.

  • Silicone adhesives and coatings extend the service life of cars. Exteriors are more resistant to rain, wind, salt, abrasion, ultraviolet radiation and chemicals. Joints last longer and overall maintenance and repair is less costly.
  • Silicones are used in a wide range of car parts including: airbags, engine gaskets, headlamps, hydraulic bearings, ignition cables, radiator seals and hoses, shock absorbers, spark plug boots and ventilation flaps.
  • Silicones help provide cushioning, providing load bearing and protective shock absorption qualities to car seats, dashboards and automotive interiors.
  • Silicone release coatings are used to allow tire manufacturers to get the tires out of their manufacturing molds and silicone rubber is used in many tires to provide long wear life and superior traction.

Silicone in Car Care Products

Car care chemists select the best performing silicones to create a desired finish for each kind of car surface. Silicones are primarily used to modify or enhance a specific characteristic of another ingredient in a polish, wax or protectant formula. One of the most commonly used features of silicone is its ability to lubricate (improve slip). The use of some types of silicone in a formula acts to make the product easier to apply and buff off.  Silicone lubrication helps reduce surface marking from wiping with bad toweling or applicators.

All this is only possible because the silicone base polymer has such a versatile range of 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.
