Viton® gaskets

Viton® gaskets are high-performance sealing components made from fluoroelastomer rubber, known for their exceptional resistance to heat, chemicals, oils, and extreme environments. Here’s a closer look:

  1. Material Composition: Viton® is a brand name for fluoroelastomer rubber developed by The Chemours Company. It’s composed of fluorine, carbon, and hydrogen atoms arranged in a polymer chain. Viton® gaskets typically contain a high percentage of fluorine, providing excellent chemical resistance and thermal stability.

  2. Properties:

    • Chemical Resistance: Viton® gaskets offer outstanding resistance to a wide range of chemicals, including acids, solvents, fuels, oils, and hydraulic fluids. This makes them suitable for applications in harsh chemical environments.
    • Temperature Resistance: Viton® gaskets can withstand high temperatures, typically ranging from -20°C to 200°C (-4°F to 392°F) and even higher in some formulations. They maintain their sealing properties over a wide temperature range, making them suitable for both low and high-temperature applications.
    • Compression Set Resistance: Viton® gaskets exhibit excellent compression set resistance, meaning they maintain their shape and sealing integrity even after prolonged compression, ensuring long-term reliability.
    • Weather Resistance: Viton® gaskets are resistant to ozone, sunlight, and weathering, making them suitable for outdoor applications where exposure to harsh environmental conditions is a concern.
    • Flexibility: Despite their high hardness, Viton® gaskets remain flexible and can conform to irregular surfaces, providing a reliable seal even on rough or uneven mating surfaces.

  3. Manufacturing Process: Viton® gaskets can be manufactured using various methods, including compression molding, injection molding, extrusion, and die-cutting. The choice of manufacturing method depends on factors such as the complexity of the gasket design and the required production volume.

  4. Applications: Viton® gaskets are widely used in industries such as automotive, aerospace, chemical processing, oil and gas, and semiconductor manufacturing. They are commonly used for sealing applications such as gaskets for engines, pumps, valves, flanges, and chemical processing equipment.

  5. Customization: Viton® gaskets can be customized to meet specific application requirements, including size, shape, thickness, hardness, and color. They can also be fabricated with adhesive backing for easy installation.

  6. Environmental Considerations: While Viton® gaskets offer excellent chemical and temperature resistance, they may not be suitable for applications requiring low-temperature flexibility or compatibility with certain fluids. Additionally, Viton® may contain additives or fillers that can impact its environmental compatibility, so it’s essential to consider these factors when selecting Viton® gaskets for specific applications.

Overall, Viton® gaskets provide superior sealing performance in demanding applications where resistance to heat, chemicals, and extreme environments is critical.

Reinforced FKM / Viton gaskets

Reinforced FKM/Viton gaskets are specialized sealing components that combine the properties of fluoroelastomer rubber (FKM or Viton) with reinforcing materials to enhance strength, durability, and performance in demanding applications. Here’s an overview:

  1. Material Composition: Reinforced FKM/Viton gaskets are typically made from fluoroelastomer rubber compounded with reinforcing materials such as aramid fibers (e.g., Kevlar), fiberglass, polyester, or metal mesh. These reinforcing materials improve the gasket’s mechanical properties, such as tensile strength, tear resistance, and dimensional stability, while maintaining the excellent chemical and temperature resistance of FKM/Viton rubber.

  2. Properties:

    • Chemical Resistance: Reinforced FKM/Viton gaskets offer outstanding resistance to a wide range of chemicals, including acids, solvents, fuels, oils, and hydraulic fluids. This makes them suitable for use in harsh chemical environments where traditional rubber gaskets may fail.
    • Temperature Resistance: FKM/Viton rubber inherently provides excellent heat resistance, typically ranging from -20°C to 200°C (-4°F to 392°F) and higher in some formulations. The reinforcing materials further enhance the gasket’s ability to withstand high temperatures, making them suitable for both low and high-temperature applications.
    • Mechanical Strength: The reinforcing materials in reinforced FKM/Viton gaskets improve mechanical properties such as tensile strength, tear resistance, and dimensional stability, making them more durable and reliable in demanding applications.
    • Compression Set Resistance: Reinforced FKM/Viton gaskets exhibit excellent compression set resistance, meaning they maintain their shape and sealing integrity even after prolonged compression, ensuring long-term reliability.
    • Flexibility: Despite their reinforced construction, FKM/Viton gaskets remain flexible and can conform to irregular surfaces, providing a reliable seal even on rough or uneven mating surfaces.

  3. Manufacturing Process: Reinforced FKM/Viton gaskets are manufactured using methods similar to standard FKM/Viton gaskets, including compression molding, injection molding, extrusion, and die-cutting. The reinforcing materials are added during the compounding process to achieve the desired properties.

  4. Applications: Reinforced FKM/Viton gaskets are used in industries such as automotive, aerospace, chemical processing, oil and gas, and semiconductor manufacturing, where high-performance sealing solutions are required. They are commonly used for sealing applications such as gaskets for engines, pumps, valves, flanges, and chemical processing equipment.

  5. Customization: Reinforced FKM/Viton gaskets can be customized to meet specific application requirements, including size, shape, thickness, hardness, and reinforcement type. They can also be fabricated with adhesive backing for easy installation.

Overall, reinforced FKM/Viton gaskets provide superior sealing performance in demanding applications where resistance to heat, chemicals, and mechanical stress is critical. Their enhanced strength, durability, and reliability make them a preferred choice for sealing solutions in various industrial and commercial sectors.
