Silicone rubber
What is Silicone Rubber?
Silicone rubber is a material suitable for harsh environments and is an excellent choice for extreme temperature applications.
Silicone is one of the materials of choice for any application that deals with environmental factors that may undermine other solutions. When it comes to extreme temperatures, silicone rubber has great resistance in both high and low temperature environments. In addition, silicone provides superior tensile strength, elongation, tear strength, and compression set at extreme temperatures compared to traditional rubber.
In addition to temperature resistance, other advantages of silicone rubber include insulation, compression set resistance, and water resistance. These advantages make silicone rubber a versatile material that can help companies invest in rubber products that can not only withstand difficult conditions, but also perform the necessary performance for a long time. Due to these factors, we regularly provide companies with silicone seals, tubing sleeves and other customized parts.

Features and advantages of silicone
More able to withstand high and low temperatures than organic rubber.
Good thermal stability.
Some silicone compounds can be used continuously for a long time even at a temperature of 200°C(392 °F), while other compounds can withstand higher temperatures for a short time.
Repels moisture and forms a tight seal.
Excellent electrical insulation, even if immersed in water will not reduce the insulation performance.
Carbon black additives can further increase the conductivity of the silicone.
It is flexible at low temperature and hard at high temperature.
At ordinary pressures, contact with steam generally causes little or no deterioration.
Low chemical reactivity.
The compounding can be done in different ways to meet any number of applications (die cutting, injection molding, extrusion).
The cutting length can be customized according to the needs of various production parts.
The filler can increase the tensile strength to about 1500PSA and increase the tear resistance to 200 pounds.
