Fluorosilicone rubber and silicone rubber are two different types of rubber materials with some significant differences in performance and applications:

Temperature resistance:

Fluorosilicone rubber generally has higher high temperature resistance and can maintain its elasticity and mechanical properties under extreme temperatures, generally operating in the range of -50°C to +250°C.
Silicone rubber also has good temperature resistance, but compared to fluorosilicone rubber, its high temperature resistance may be lower, and it can generally work in the range of -60°C to +230°C.
Chemical resistance:

Fluorosilicone rubber usually has better corrosion resistance to chemical substances and can work stably in more chemical environments, such as acids, alkalis, solvents, etc.
Silicone rubber also has good chemical resistance, but may be affected by some highly corrosive chemicals.
Oxidation stability:

Fluorosilicone rubber has better oxidation stability and can work for a long time in oxidizing environments such as oxygen and ozone without aging easily.
The stability of silicone rubber in oxidative environments is relatively low, and problems such as aging and hardening may occur.
Mechanical behavior:

Fluorosilicone rubber and silicone rubber may have some differences in mechanical properties, including differences in elastic modulus, tensile strength, etc. The specific performance depends on the specific formula and preparation process.
price:

Generally speaking, the price of fluorosilicone rubber is higher than that of silicone rubber. This is mainly because the raw material cost of fluorosilicone rubber is higher and the preparation process is relatively complicated.
In summary, fluorosilicone rubber and silicone rubber are different in terms of temperature resistance, chemical resistance, oxidation stability, etc., and the selection should be based on specific application requirements.
