Viton Sheet Material: Properties and Applications Viton is a high-performance fluoroelastomer known for its exceptional resistance to heat, chemicals, and oils. It is widely used in demanding industrial applications where durability and reliability are critical. Viton sheet material, available in various thicknesses and formulations, offers excellent mechanical properties and long-term performance in harsh environments. Key Properties 1. Temperature Resistance – Viton sheets can withstand continuous temperatures ranging from -20°C to +200°C (-4°F to +392°F), with some specialized grades capable of handling higher extremes. This makes them ideal for high-heat applications such as gaskets in engines and industrial machinery. 2. Chemical Resistance – Viton exhibits outstanding resistance to oils, fuels, acids, and solvents. It performs well against aggressive chemicals like hydrocarbons, chlorinated compounds, and aromatics, making it suitable for chemical processing and oil & gas industries. 3. Oil and Fuel Resistance – Unlike many elastomers, Viton does not swell or degrade when exposed to petroleum-based fluids, lubricants, or biofuels. This property is essential for automotive and aerospace sealing applications. 4. Compression Set Resistance – Viton sheets maintain their shape and sealing ability even after prolonged compression, ensuring long-term performance in gaskets and seals. 5. Weather and Ozone Resistance – Viton resists degradation from UV exposure, ozone, and weathering, making it suitable for outdoor applications. Common Applications - Gaskets & Seals – Viton sheets are widely used to manufacture gaskets, O-rings, and custom seals in automotive, aerospace, and industrial equipment. - Chemical Processing – Due to its chemical inertness, Viton is used in linings, diaphragms, and valve seals in corrosive environments. - Oil & Gas Industry – Viton sheets serve as sealing materials in pipelines, pumps, and drilling equipment where exposure to hydrocarbons is frequent. - Food & Pharmaceutical – FDA-compliant Viton grades are used in food processing and pharmaceutical manufacturing where contamination resistance is crucial. - Aerospace & Automotive – Viton is used in fuel systems, engine components, and hydraulic seals due to its high-temperature and fuel resistance. Formulations and Grades Viton sheets come in different grades, including: - Standard Viton (FKM) – General-purpose grade for most industrial applications. - High-Fluorine Viton – Enhanced chemical resistance for aggressive media. - Low-Temperature Viton – Improved flexibility in sub-zero conditions. Conclusion Viton sheet material is a versatile and durable elastomer solution for industries requiring resistance to extreme temperatures, chemicals, and oils. Its superior performance in harsh conditions makes it a preferred choice for critical sealing and gasketing applications. Whether in automotive, chemical processing, or oil & gas, Viton ensures reliability and longevity in demanding environments.
