About Silicone Rubber

Silicone rubber is a synthetic elastomer made from silicone, which is a polymer containing silicon, oxygen, carbon, and hydrogen. It is a versatile material that can be formulated to have a range of properties, including high and low-temperature resistance, electrical insulation, and water resistance. Silicone rubber can be manufactured in various forms, including sheets, tubes, and extrusions, and can be moulded into complex shapes.

Silicone rubber is widely used in a variety of industries, including aerospace, automotive, construction, electronics, medical, and food processing. It is valued for its excellent heat resistance, weatherability, and aging resistance. Additionally, silicone rubber is also biocompatible, which makes it suitable for medical and pharmaceutical applications. In comparison to other elastomers, silicone rubber has low compression set, which means that it can maintain its shape and elasticity over time even when subjected to stress or pressure. Overall, silicone rubber is a highly versatile material with a range of unique properties that make it ideal for many different applications.

Silicone rubber gaskets offer several benefits, including:

  • High temperature resistance: Silicone rubber gaskets can withstand high temperatures without losing their physical properties or becoming brittle. They can maintain their elasticity and sealing properties at temperatures ranging from -50°C to 200°C, and even up to 250°C for some formulations.
  • Excellent sealing properties: Silicone rubber gaskets can provide an excellent seal due to their ability to conform to irregular surfaces and provide a tight fit. They can also resist compression set, meaning they can maintain their shape and elasticity over time.
  • Resistance to environmental factors: Silicone rubber gaskets have good resistance to UV radiation, ozone, and other environmental factors, making them suitable for outdoor and harsh environments.
  • Chemical resistance: Silicone rubber gaskets have good resistance to a wide range of chemicals, including water, alcohol, acids, and bases.
  • Biocompatibility: Silicone rubber is non-toxic and biocompatible, making it ideal for use in medical and food processing applications.
  • Easy to fabricate: Silicone rubber gaskets can be easily fabricated into different shapes and sizes using different manufacturing methods, including compression moulding, injection

Silicone rubber gaskets offer excellent sealing properties and can withstand high temperatures and harsh environments, making them ideal for a wide range of applications.

Silicone rubber offers good chemical resistance, which means it can withstand exposure to various chemicals without degrading or losing its physical properties. Some of the benefits of silicone rubber’s chemical resistance include:

  • Resistance to water: Silicone rubber is highly resistant to water and can maintain its physical properties even after prolonged exposure to water.
  • Resistance to acids and bases: Silicone rubber has good resistance to acids and bases, which makes it suitable for use in applications that involve exposure to acidic or basic environments.
  • Resistance to ozone and UV radiation: Silicone rubber has good resistance to ozone and UV radiation, which means it can maintain its physical properties even when exposed to these environmental factors.
  • Resistance to oils and solvents: Silicone rubber has good resistance to many oils and solvents, making it suitable for use in applications that involve exposure to these substances.
  • Resistance to chemicals used in cleaning: Silicone rubber can resist the chemicals used in cleaning, making it a suitable material for use in food processing, medical devices, and other applications that require regular cleaning.

Overall, the chemical resistance of silicone rubber makes it a versatile material for use in a wide range of applications, including automotive, aerospace, medical, food processing, and industrial applications.
