The Three Major Properties of Silicone Rubber Products

Ⅰ. Silicone rubber


Silicone rubber is a unique synthetic elastomer made of a polymer cross-linked by oxygen and silicon. It perfectly balances mechanical properties and chemical properties, so it can meet the requirements of many demanding applications today. Now more and more products are made of silicone rubber.


Ⅱ. The three major properties of silicone rubber products


1. High 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-300 degrees. If appropriate silicone rubber fillers and silicone rubber high-temperature additives are selected, the operating 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 degrees and 5 years at 150 degrees, and it is not easy to age.


2. Low 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 low temperatures of -50 degrees to -60 degrees.


3. Air 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.


Silicone rubber is a new type of polymer material. The product has a series of characteristics such as high and low temperature resistance, aging resistance, excellent electrical properties, and physiological inertia. It is widely used in various fields such as aviation, aerospace, electronic and electrical, automotive, machinery, daily use, etc. , with a broad market space and good development prospects.
