Viton is the most well know fluoroelastomer. There are multiple variations of Vitons. The most common compounds are Viton A, Viton B, Viton F, Viton B7 Viton GLT, Viton GFLT and Viton ETP. This class of elastomers is a family comprising copolymers of hexafluoropropylene and vinylidene fluoride, terpolymers.
If your seals exhibit thermal or chemical degradation, we can help you by analyzing your failures and recommending the appropriate grade of Viton to solve your problem. They also require less compression to make a seal, so they offer a longer service life.
This property is determined by the type and the relative amounts of the specific monomers that make up the polymer. Fluid resistance generally improves with increasing levels of fluorine (see the table below). Viton has a wide temperature tolerance which ranges from -4F to 410F (-20C to 210C).
The high temperatures Viton can withstand make it ideal for high temperature applications. Special formulations permit its use in static applications down to -54°C. Also, Viton has proven to be satisfactory for static seals used under conditions approaching absolute zero.
Search Viton Seals. They have grown major importance in the sealing industry and are even considered the most significant single elastomer developed in recent history. Viton seals provide an indefinite seal for temperatures up to 400°F, and for temperatures up to 600°F they offer an excellent seal for more than hours. Both are types of rubber polymers that are compounded for low compression set.
This means that they will recover well after a fixed time under specified squeeze at a given temperature. It is recommended with good mechanical properties.
VITON (C)" and "Shore A" is not enough information to characterize a sealing material. Viton or more general Fluorocarbon rubber (FKM or FPM)includes different materials. They can have different fluorine content (between and % fluorine) and hence very different swelling behaviour in solvents as e. Find Instant Quality Info Now! These seals or gaskets are commonly used to seal leaks, valves, pumps and similar.
FKM rubber has good resistance to compression, low gas permeability and resistance to ozone and sunlight. Although originally formulated for use in aerospace applications, FKM seals are now widely used in the automotive, equipment, fluid power and chemical process industries.
It has very good resistance to aliphatic hydrocarbon fluids, animal and vegetable oils, and alkalis. O-rings and gaskets are seals that are compressed in an area between two or more surfaces that are crucial to the functionality of machinery.
They help join mechanical mechanisms together and prevent leakage of fluids. Viton Rubber is a premium material that combines excellent chemical compatibility with outstanding temperature resistance, a high density and long lasting sealing performance. VF2), hexafluoropropylene (HFP), and tetrafluoroethylene (TFE). Free FedEx Day shipping on orders of $50.
However, it can effectively seal mechanical objects at low temperatures to –22°F. Buna is effective to 250°F. Viton seals are rendered ineffective at temperatures below 5°F, with the material becoming hard and inflexible.
Gli elastomeri in FKM (o FPM per gli standard ISO) fanno parte della famiglia degli tecnopolimeri fluorurati. Standards are in stock or custom manufactured to your specifications. A1: Use EPDM seals. Q2: Is the chemical oil based like 4- MSO and Crop Oil?

This material has an excellent tolerance for high temperatures, resistance to oils, fuels and hydraulic fluids as well as aromatics and solvents.
