Benefits & Advantages of Silicone Rubber

This post is also available in: Spanish Russian

In this article, we introduce the many benefits and advantages of silicone rubber.

  • Withstands high & low temperatures far better than organic rubber
  • Good thermal stability
  • Repels water & forms tight seals
  • Excellent electrical insulation, no decline in insulation performance even when immersed in water, making it an ideal insulating material
  • Flexible at low temperatures, stiffens up at higher temperatures
  • Under ordinary pressure, contact with steam typically causes little or no deterioration

  • Flame retardant, will not ignite easily. Some products received UL94 V-0 certification according to the UL94 (USA) standards for flammability classification.
  • Unlike most organic elastomers such as EPDM and neoprene, the compression set of silicone rubber is consistent over a wide range of temperatures from -60° to +250°C. The selection of a proper curing agent and post-curing is particularly recommended when using silicone material to make molded products that require a low compression set.
  • Customizable for specific applications by adjusting the compound recipe by selecting the proper curing agent and/or post-curing the compound to improve resistance to flames, steam & hot water (over 150C)
  • Low chemical reactivity
Silicone rubber stands up well to sunlight

Why Silicone is the Ideal Material for Extreme Temperatures

Silicone rubber withstands high and low temperatures far better than their organic rubber counterparts.

  • Ability to be used continuously at 150°C (302° F) with virtually no change in its properties.
  • Certain silicone compounds can withstand use even at 200°C (392° F) for 10,000 hours or more.
  • Some silicone rubber products can withstand heat upwards of 350°C (662° F) for short periods.

Silicone rubber also exhibits excellent resistance to cold temperatures.

  • Embrittlement point for some silicone parts is between -60° to -70°C, (-76° to -94° F) (organic rubber is between -20° to -30°C, (-4 to -22° F)
  • Some silicone products are able to withstand extremely low temperatures, keeping their elasticity at -100°C (-148° F) and below.
