Silicone Rubber Products

If you need a rubber product that can withstand difficult environments, silicone rubber can be an excellent choice for your applications. Timco Rubber can work with your business to provide custom-designed silicone parts made specifically to address your application’s performance needs.

Silicone Rubber: A Material Made for Difficult Environments

Silicone is one of the materials of choice for any application that deals with environmental factors that can break down other solutions. When it comes to extreme temperature, silicone rubber offers a great range of resistance in both hot and cold environments. In addition, silicone offers far superior tensile strength, elongation, tear strength, and compression sets in extreme temperatures than conventional rubbers.

In addition to temperature resistance, other advantages of silicone rubber include insulation from electricity, compression set resistance, and the ability to repel water. Because of these advantages, silicone rubber is a versatile material that can help businesses invest in rubber products that not only withstand difficult conditions, but also perform as necessary for a long time.

Silicone Benefits and Advantages image

Silicone Benefits and Advantages

  • Withstands high and low temperatures far better than organic rubber
  • Good thermal stability
  • Certain silicone compounds can withstand long-term, continuous use even at 200°C (392°F), while others may be able to withstand higher temperatures for short periods of use
  • Repels water and forms tight seals
  • Excellent electrical insulation, with no decline in insulation performance even when immersed in water
  • Carbon black additives can further increase silicone's electrical conductivity
  • Flexible at low temperatures, stiffens up at higher temperatures
  • Under ordinary pressure, contact with steam typically causes little or no deterioration
  • Flame retardant with additives, with some products receiving UL94 V-0 certification according to the UL94 (USA) standards for flammability classification
  • Low chemical reactivity
  • Can be compounded in different ways to meet any number of applications
  • Fillers can improve tensile strength to roughly 1,500 PSA and tear resistance up to 200 lbs.
