The uses of silicones

FAQ 01.09.2022

What is silicone used for?

Many types of silicone are used in an almost infinite number of applications and industries. This is because they are versatile, chemically stable, thermally resistant (both at hot and cold temperatures), durable, reliable and offer specific qualities like biocompatibility for use in medical devices or food processing.  

Here is a representative (but far from exhaustive) list of some major applications:

  • In construction, they are particularly appreciated because they can bond almost all materials, including concrete, glass, granite, marble, aluminum, steel, plastics, etc. They are durable and resist deterioration caused by rough weather conditions, moisture, sunlight (including UV rays) and pollution.
  • In cooking, both at home and in restaurants, silicones are very useful for making molds, for baking in particular, because they are flexible, shock-resistant and available in a wide range of shapes. Silicones are also bacteria-and-heat resistant and very durable, even at very hot temperatures.
  • Silicone technologies are critical in electrical and electronic applications to ensure long-term stability and performance of increasingly miniaturized sensitive components in mobile and other sophisticated electronic devices, such as computers and tablets.
  • In renewable energy production, silicone potting, sealing and insulating products for solar, wind and hydroelectric production have become essential because they are transparent (e.g. for solar panels), stable for all systems, resist extreme weather conditions, protect against UV damage and are neutral to aggression by corrosive by-products. They contribute to all energy sectors by generating significant cost reductions and, in the long run, to the Total Cost of Operations (TCO).
  • In medical applications, biocompatible silicones are safe for humans, both when used on the skin or in the body. They facilitate healing, lessen scaring in bandages because they offer good adhesion and are easily removed, reduce patient discomfort and enable the making of healing and life-enhancing devices, such as prostheses.
  • In hybrid and electrical vehicles, silicones encapsulate the entire battery pack to stabilize its conductivity and insulation, protect against vibration, heat dissipation, and ensure water and dust proofing.
  • In all types of vehicles, silicones are used for the different layers of airbags to ensure sealing and fabric strength, thus contributing to increased safety and reducing serious or fatal road injuries by contributing to faster and accurate inflation at the right pressure point, while avoiding cracks or leaks.
