Is Silicone a FKM?
When it comes to industrial applications such as seals and gaskets, choosing the right material is crucial to ensure durability and performance. Two commonly used materials are silicone and FKM (fluorocarbon rubber). While both materials possess desirable properties, it is important to understand the differences and determine whether silicone can be considered a FKM. In this article, we will explore the characteristics of both materials and shed light on this question.
Silicone: A Versatile Option.
Silicone is a synthetic polymer that offers excellent resistance to high and low temperatures, making it suitable for a wide range of applications. It is known for its superb flexibility, resilience, and electrical insulation properties. Silicone is resistant to water, most chemicals, and UV radiation, making it an ideal choice for outdoor applications. Additionally, it has a low compression set, meaning it can maintain its original shape after being compressed. These properties make silicone an attractive option for various industries, including automotive, aerospace, and medical.
FKM: Strength against Harsh Environments.
FKM, on the other hand, is a high-performance synthetic elastomer made of fluoropolymer elastomers. It is known for its exceptional resistance to chemicals, fuels, oils, and high temperatures. FKM exhibits excellent mechanical properties, including high tensile strength and elongation at break, making it highly durable. This material is commonly used in applications that require resistance against harsh fluids, such as seals used in the oil and gas industry, aerospace, and automotive industry.
Differences between Silicone and FKM.
While both silicone and FKM offer incredible properties, they differ in terms of their chemical composition and resistance to specific substances. FKM has a broader range of resistance against harsh chemicals, fuels, and oils compared to silicone. It can withstand aggressive substances that would otherwise cause significant damage to silicone. Moreover, FKM has higher temperature resistance, making it more suitable for applications that involve extreme heat.
Can Silicone be Considered a FKM?
The answer to whether silicone can be considered a FKM is no. Although silicone offers impressive properties like high and low-temperature resistance, it does not possess the same level of chemical resistance as FKM. Additionally, FKM outperforms silicone in terms of high-temperature applications. Therefore, it is essential to choose the appropriate material based on the specific requirements of the application.
Conclusion.
In conclusion, silicone and FKM are both reliable materials used in various industries for their unique properties. Silicone is highly versatile, with excellent temperature resistance, flexibility, and electrical insulation. However, it falls short when it comes to chemical resistance compared to FKM. FKM, with its superior resistance to harsh chemicals, fuels, oils, and high temperatures, is the material of choice for applications that require durability and strength. While silicone cannot be considered a FKM, it still offers exceptional performance in its own right. Therefore, by understanding the characteristics of each material, manufacturers can make informed decisions in selecting the most suitable material for their applications.
