Why Silicone Rubber?

​

Silicone rubber is one of the most commonly used synthetic rubbers on the market. It is composed of silicone bonded with hydrogen, carbon, and oxygen to create cross-linked polymers reinforced with silica. The result is a unique synthetic elastomer that offers the ideal balance of mechanical and chemical characteristics for the most demanding applications.

​

Silicone rubber offers distinct advantages over other elastomers, including:

​

  • Environmental resistance: Silicone rubber exhibits a high level of resistance to harsh environmental factors, including UV radiation, open flames, extreme temperatures, and corrosive chemicals.

  • Thermal stability: Silicone rubber will retain its shape, durability, and flexibility in extreme hot and cold temperatures.

  • Moisture Sealant: Silicone rubber is water repellent and malleable, which makes it an excellent sealant.

  • Easy sterilization: Silicone rubber can withstand high temperatures, harsh chemicals, and radiation exposure required with FDA-regulated sterilization methods, making it a useful medical-grade material.

  • Color friendly: Silicone rubber is easy to color prior to the curing process so that it exhibits a lasting, vivid shade.

  • Electrical properties: Silicone rubber is an excellent electrical insulator, however, the addition of metal or carbon black can improve its conductive properties.

  • Range of hardness: Silicone rubber can be formulated to exhibit different ranges of flexibility and hardness, depending on the needs of the application.

  • Durable and reliable: Silicone is highly durable and retains its shape and flexibility in extreme conditions, making it a particularly reliable material for use in critical applications.

  • With its ability to conform to the needs of nearly any application, it is no surprise that silicone rubber is one of the most widely used materials.
