Fluorosilicone rubber and silicone rubber are two common rubber materials with significant differences in performance and applications. Firstly, fluorosilicone rubber has higher high temperature resistance and can maintain good performance in the temperature range of -60 ° C to+250 ° C. However, the high temperature resistance of silicone rubber is slightly inferior and can only be used in the temperature range of -50 ° C to+200 ° C.
Secondly, fluorosilicone rubber has better chemical resistance and can resist the erosion of various chemicals, so it is widely used in the chemical industry. Silicone rubber, on the other hand, is less resistant to some chemicals than fluorosilicone rubber, so it may be affected in specific environments.
In addition, fluorosilicone rubber has better aging resistance and can maintain good elasticity and mechanical properties for a long time, while silicone rubber may harden and lose elasticity after long-term use.
Overall, fluorosilicone rubber performs better than silicone rubber in terms of high temperature, chemical corrosion, and aging. Therefore, in some fields with high performance requirements, such as aerospace, automotive manufacturing, and chemical engineering, fluorosilicone rubber is more favored. Silicone rubber is more common in applications that meet general requirements, such as food processing, medical devices, and daily necessities.
Overall, the choice between fluorosilicone rubber and silicone rubber depends on the specific usage environment and requirements, and requires comprehensive consideration of factors such as material performance, cost, and service life. Both fluorosilicone rubber and silicone rubber have their own advantages and applicability, and with the right choice, they can achieve the best performance and effect.
