### Is FKM rubber better than silicone?
**Q: Is FKM rubber better than silicone?**.
**A: Yes, FKM rubber is generally considered to be better than silicone in certain applications.**.
### Why is FKM rubber considered better than silicone in certain applications?
**Q: Why is FKM rubber considered better than silicone in certain applications?**.
**A: FKM rubber, also known as fluorocarbon rubber, offers superior chemical resistance, high temperature stability, and excellent mechanical properties compared to silicone. FKM rubber can withstand a wider range of temperatures, from -20°C to 200°C, while silicone is limited to temperatures between -60°C and 230°C. This makes FKM rubber ideal for applications requiring resistance to harsh chemicals, extreme temperatures, and high pressures.**.
### In what applications is FKM rubber typically preferred over silicone?
**Q: In what applications is FKM rubber typically preferred over silicone?**.
**A: FKM rubber is commonly used in industries such as automotive, aerospace, oil and gas, and chemical processing where resistance to fuels, oils, solvents, and high temperatures is crucial. It is also preferred in applications where sealing performance and durability are key factors. Silicone, on the other hand, is preferred in applications where flexibility, low toxicity, and FDA compliance are important, such as in food and medical industries.**.
### What are the limitations of using FKM rubber over silicone?
**Q: What are the limitations of using FKM rubber over silicone?**.
**A: While FKM rubber offers superior performance in harsh environments, it is more expensive than silicone. FKM rubber also tends to have lower flexibility and compression set resistance compared to silicone. Additionally, FKM rubber may not be suitable for applications requiring extremely low temperatures, as it becomes stiff and brittle below -20°C. Silicone, on the other hand, remains flexible at low temperatures, making it a more suitable choice for cold temperature applications.**.
In conclusion, while FKM rubber is generally considered better than silicone in applications requiring chemical resistance, high temperatures, and mechanical strength, the choice between the two materials ultimately depends on the specific requirements of the application.
