Fluorosilicone rubber is a special synthetic rubber that combines the advantages of fluororubber and silicone rubber, so it has excellent high and low temperature performance. The following is a detailed analysis of the high and low temperature performance of fluorosilicone rubber:



High temperature performance:
Fluorosilicone rubber exhibits excellent stability in high temperature environments. Because its molecular structure contains fluorine atoms and silicon atoms, both of which have strong bond energy, fluorosilicone rubber is not easy to decompose or degrade at high temperatures.
In high temperature applications, the tensile strength and tear strength of fluorosilicone rubber are generally better than those of fluororubber. This means that under high temperature conditions, fluorosilicone rubber can maintain better structural integrity and mechanical properties.
In addition, fluorosilicone rubber also has good thermal oxidation resistance and can be used for a long time at high temperatures without significant performance degradation.

Low temperature performance:
Fluorosilicone rubber has a low glass transition temperature, which means that under low temperature conditions, its molecular chain can still maintain good mobility and is not prone to brittleness or breakage.
Therefore, the elasticity and flexibility of fluorosilicone rubber at low temperatures are generally better than those of fluororubber, and it can maintain good performance in a wider temperature range.
In extreme low temperature environments, fluorosilicone rubber can still maintain a certain mechanical strength and elongation, which gives it a unique advantage in low temperature applications.

Weather resistance:
Fluorosilicone rubber not only performs well in high and low temperature environments, but also has good weather resistance. It can resist the erosion of environmental factors such as ultraviolet rays and ozone, and maintain stable performance for a long time.
This makes fluorosilicone rubber highly reliable in applications outdoors or in harsh environments.

In summary, fluorosilicone rubber has excellent high and low temperature performance, especially better tensile strength and tear strength in high temperature applications. Therefore, fluorosilicone rubber has a wide range of application prospects in high temperature seals, pipes, gaskets and other applications in the fields of aviation, aerospace, automobiles, chemicals, etc. At the same time, its good low temperature performance also makes the application of fluorosilicone rubber in low temperature environments have unique advantages.
