FKM stands for Fluoroelastomer, which is a type of synthetic rubber known for its exceptional resistance to chemicals, extreme temperatures, and harsh environmental conditions. It is commonly used in various industries, including automotive, aerospace, and oil and gas.
FKM exhibits excellent thermal stability, withstanding temperatures ranging from -40°C to +250°C (-40°F to +482°F) without losing its mechanical properties. This makes it suitable for applications that require high-temperature resistance.
Another notable property of FKM is its outstanding resistance to chemicals, fuels, oils, acids, and solvents. It can withstand exposure to a wide range of aggressive substances, making it an ideal material for seals, O-rings, gaskets, and other products in industries where chemical resistance is critical.
Beyond its resilience to extreme conditions, FKM also demonstrates good mechanical properties, such as high tensile strength and excellent tear resistance. Its durability and ability to maintain sealing performance over extended periods of use make it a reliable choice for demanding sealing applications.
FKM is available in various grades, each designed to meet specific industrial needs. Different grades offer varying levels of temperature resistance, chemical compatibility, and hardness. The most common FKM compounds include Viton®, Tecnoflon®, and Dai-El.
Overall, FKM is a versatile elastomer that combines excellent chemical resistance, high-temperature capabilities, and robust mechanical properties, making it a preferred choice for many applications where durability, reliability, and resistance to extreme conditions are paramount.
