About Silicone Rubber Extrusion

Silicone rubber extrusion is a manufacturing process used to create long, continuous lengths of silicone rubber with a specific cross-sectional profile. During the extrusion process, raw silicone rubber material is heated and then forced through a die that has the desired shape of the final product. The extruded silicone rubber is then cooled and cut to the desired length.

Silicone rubber extrusions can be produced in a variety of shapes and sizes, including round, square, rectangular, and custom shapes. They can also have various surface finishes, such as smooth, textured, or ribbed.

Silicone rubber extrusions are used in a wide range of industries and applications, including automotive, aerospace, medical, food and beverage, and electronics. They can be used as seals, gaskets, tubing, bumpers, and other applications where a flexible, durable, and heat-resistant material is required. Silicone rubber offers excellent resistance to extreme temperatures, UV light, ozone, moisture, and many chemicals, making it an ideal material for demanding applications.

Silicone rubber extrusions offer several key chemical properties that make them useful in a variety of applications. These properties include:

  • High temperature resistance: Silicone rubber can withstand extreme temperatures, both hot and cold, without breaking down or degrading. It can operate in temperatures ranging from -60°C to 230°C, making it suitable for use in harsh environments.
  • Chemical resistance: Silicone rubber is resistant to many chemicals, including acids, bases, oils, and solvents. It is also resistant to oxidation, UV light, and ozone, which helps to prevent the material from breaking down over time.
  • Electrical insulation: Silicone rubber is an excellent electrical insulator, making it ideal for use in electrical and electronic applications. It can withstand high voltages and is resistant to corona discharge.
  • Water and weather resistance: Silicone rubber is highly resistant to water and moisture, making it an ideal material for outdoor applications. It is also resistant to weathering, including UV light and ozone exposure.

Silicone rubber extrusions are used in a wide range of applications across many industries, including:

  • Aerospace: Silicone rubber extrusions are used in aircraft and spacecraft applications due to their resistance to extreme temperatures and harsh chemicals.
  • Automotive: Silicone rubber extrusions are used in automotive applications, including door seals, weatherstripping, and gaskets, due to their ability to withstand high temperatures and exposure to fuels, oils, and other chemicals.
  • Medical: Silicone rubber extrusions are used in medical devices and equipment due to their biocompatibility, non-reactivity, and sterilization resistance.
  • Electrical and electronics: Silicone rubber extrusions are used in electrical and electronic applications due to their electrical insulation properties and resistance to corona discharge.
  • Food and beverage: Silicone rubber extrusions are used in food and beverage processing equipment due to their resistance to high temperatures, chemicals, and moisture.
  • Construction: Silicone rubber extrusions are used in construction applications, including glazing seals, curtain walls, and weatherstripping, due to their ability to withstand extreme weather conditions and exposure to UV light.

Overall, silicone rubber extrusions offer a unique combination of properties, including high temperature and chemical resistance, electrical insulation, and water and weather resistance, which makes them useful in a wide range of industries and applications.

We are able to manufacture a wide range of silicone rubber products using bespoke or existing tooling in quantities from small batches to large production orders.
