FKM (fluoroelastomer), commonly known by the trade name Viton®, is a synthetic rubber known for its exceptional resistance to heat, chemicals, oils, and fuels. FKM Viton rubber cord is a specialized sealing material that offers superior performance in demanding environments. Here are some key features and applications:

1. Chemical Resistance: FKM Viton rubber cord exhibits excellent resistance to a wide range of chemicals, including acids, bases, solvents, and fuels. This makes it suitable for use in applications where exposure to aggressive chemicals is common, such as chemical processing, oil and gas industries, and automotive applications.

2. High Temperature Resistance: FKM Viton rubber cord can withstand high temperatures without losing its physical properties. It remains flexible and resilient even at elevated temperatures, making it ideal for sealing applications in engines, exhaust systems, and other high-temperature environments.

3. Oil and Fuel Resistance: FKM Viton rubber cord is highly resistant to oils, fuels, and lubricants, including synthetic and mineral-based oils. It maintains its integrity and sealing properties when in contact with these substances, making it suitable for use in automotive seals, fuel systems, and hydraulic systems.

4. Sealing Performance: FKM Viton rubber cord provides excellent sealing performance due to its resilience, low compression set, and resistance to compression. It forms a reliable seal even under high-pressure conditions, making it suitable for use in gaskets, O-rings, and other sealing applications.

5. Weather Resistance: FKM Viton rubber cord has good resistance to weathering, ozone, and UV radiation, making it suitable for outdoor applications where exposure to sunlight and environmental elements is a concern.

6. Aerospace and Military Applications: Due to its exceptional performance in extreme conditions, FKM Viton rubber cord is widely used in aerospace, defense, and military applications, including aircraft seals, missile systems, and fuel handling systems.

7. Food and Pharmaceutical Applications: Certain grades of FKM Viton rubber cord are compliant with FDA (Food and Drug Administration) regulations, making them suitable for use in food processing, pharmaceutical, and medical applications where strict hygiene and safety standards must be met.

FKM Viton rubber cord is available in various diameters, hardness levels (durometer), and colors to suit different sealing requirements and application specifications. It can be easily cut, molded, or formed to create custom seals and gaskets for specific industrial or commercial applications.
