Three Performances Of Silicone Rubber Products

- Sep 03, 2020-

In fact, ordinary silicone rubber raw materials contain precipitated substances, and its color will show translucent or milky white color. What are the three major properties of silicone rubber products? So today, what are the three major properties of silicone rubber products for popular science?



①High temperature resistance

The most notable feature of silicone rubber is strong high temperature stability and can be used for a long time in an environment of 250 degrees to 300 degrees. If appropriate silicone rubber fillers and silicone rubber high-temperature additives are selected, the use temperature can be as high as 375 degrees and can withstand instantaneous high temperatures of thousands of degrees. It is estimated that the service life of silicone rubber can be up to 20 years at 120°C and 5 years at 150°C, and it is not easy to age.

②Low temperature resistance flexibility

Silicone rubber products have inherent low-temperature flexibility. Silicone product processing or other synthetic rubbers have a low embrittlement point. Silicone rubber generally can work normally at a low temperature of -50 degrees to -60 degrees.


③Air permeability

Silicone rubber film has good air permeability. The air permeability at room temperature to air, nitrogen, oxygen, carbon dioxide and other gases is 30-50 times higher than that of natural rubber.
