Introduction
FKM (also known as Viton) fluoroelastomer rubber is renowned for its exceptional resistance to high temperatures, chemicals, and oils. These properties make it ideal for demanding applications in industries such as aerospace, automotive, and chemical processing. However, working with FKM rubber presents several complexities that require specialized knowledge and expertise. M&K International Group has a proven track record in managing these challenges effectively, offering custom solutions, and even integrating FKM rubber with metal and plastic to enhance product performance.
Key Points about FKM/Viton
- Chemical Resistance: Viton/FKM is highly resistant to a wide range of chemicals, including fuels, oils, and solvents, making it suitable for use in harsh environments.
- Temperature Resistance: It can withstand high temperatures up to 250°C (482°F) and low temperatures down to -20°C (-4°F), providing flexibility across a broad temperature range.
- Durability: This material maintains its properties over extended periods, ensuring durability and reliability in demanding applications.
Applications
- Automotive: Used in seals, gaskets, and O-rings that must resist fuel and high temperatures.
- Aerospace: Ideal for fuel systems and hydraulic applications due to its high chemical and thermal resistance.
- Chemical Processing: Employed in seals and gaskets that come into contact with aggressive chemicals.
The Complexities of Working with FKM Rubber
FKM rubber’s unique properties stem from its fluorine content, which contributes to its high chemical and thermal resistance. However, these advantages also bring about several challenges:
- Processing and Curing: FKM requires high temperatures and precise conditions for curing. The vulcanization process must be carefully controlled to achieve the desired physical properties, such as elasticity, tensile strength, and resistance to degradation.
- Material Compatibility: FKM’s compatibility with other materials must be considered to prevent chemical reactions that could compromise its integrity. This is particularly important in applications involving aggressive chemicals or high temperatures.
- Cost: FKM is more expensive than many other elastomers due to its complex manufacturing process and the cost of raw materials. Efficient use of materials and optimization of production processes are essential to manage costs effectively.
- Adhesion to Metal and Plastic: Binding FKM rubber to metal castings, machined components, and plastics poses additional challenges. The bonding process must ensure a strong and durable adhesion to maintain the performance of the final product under harsh conditions.
