Viton® is a high-temperature synthetic rubber compound used primarily in the oil, gas, and chemical industries. It has been derived from butadiene which is found in natural rubber. Viton® combines butadiene with hydrogen sulfide (HS) to create a new type of material that not only provides improved physical properties such as elasticity, impact resistance, and heat resistance but also exhibits exceptional chemical stability.
How are Viton® Gaskets Used?
Viton® gaskets repel a wide range of chemicals and are often used in corrosive or high-temperature environments. Viton® chemical resistance, compression set, low-temperature flexibility, and low compressibility make it the best choice for applications such as catalysis, desulfurization, heat exchange systems, and process equipment. Its weatherability means that it is ideal for service under both wet and dry conditions.
What are the Applications?
As the main material for many types of industrial gaskets, Viton® is used in a wide variety of applications including:
Viton® has been used in medical products such as catheters and blood tubes to prevent bacteria from growing inside. It is also used in vacuum septums to prevent air from escaping during the pump cycles. Viton® is also used as a sealant on oil drilling equipment such as pumps and tubing due to its high chemical resistance and low price.
Viton® Gasket & Seal Material
Viton® is a registered trademark of DuPont. It has been used in the automotive, contracting, and engineering industries since the 1920s. It became widely used as a sealer on metal or plastic surfaces to create a gas and watertight seal for valves, fittings, exhaust systems, and more. Today it is most commonly known as an anti-leak gasket for glass windows.
Viton® is a fluoroplastic elastomer. Its unique properties make it ideal for industrial and construction applications. It possesses high tensile strength, excellent stem flexibility, and resistance to weathering, ozone, sunlight, thermal shock, steam at 400°F for 20 minutes, and hot water up to 180°F. These features make it the right product for almost any durable product application.
For many years, Viton® Gaskets washers and seals were primarily used as petroleum-based products. Their most common applications are in high-performance racing engines, motorhomes, and small watercraft, as well as jet engine components. Today, Viton® has become popular for a myriad of applications including HVAC systems because it features a low coefficient of friction that results in excellent sealability and at the same time, has superior elasticity that allows for expansion and contraction.
Viton® Gasket Material Grades
Viton® gasket material grades are custom engineered to meet the needs of OEMs, with standard compounds that have been developed to meet the requirements of most applications. Whatever your needs, Gorilla Gasket has a Viton® compound that will satisfy your product design goals. The gasket material compounds are manufactured in accordance with ASTM D2240 and ASTM D2240M standards.
With over a half a century of experience, Viton® gasket material grades are the ideal choice for seals in applications where the highest mechanical and thermal properties are required.
