The Uses Of Viton ® (FKM Fluoroelastomer) Rubber

The rubber products that are produced that use natural rubber like India rubber derived from Rubber trees are made up of organic-compound isoprene-polymers, along with water in addition to other organics that exhibit mechanical properties that are good. However, natural rubber is associated with restricted petroleum product and thermal permanence compatibility.

The synthetic rubbers are elastomers or polymers that are produced from the synthesized petroleum products. These products are typically produced with the use of either an isoprene/isobutylene combination or chloroprene. In most cases the synthetic rubbers display increased chemical and mechanical properties along with endurances.

Viton ® (FKM Fluoroelastomer) Rubber

Viton ® (FKM Fluoroelastomer) of fluorocarbon (floronated hydrocarbon) is a rubber product that is trademarked and produced by DuPont Performance Elastomers). Viton ® (FKM Fluoroelastomer) is a reference to all the DuPont fluoro-rubber types generally sold as a Viton ® (FKM Fluoroelastomer) gasket sheet. The different fluoroelastomer types possess differing swell behaviors along with their compression/processing set resistance. For this reason, the manufacturers produce fluoroelastomer compounds that are appropriate in order to match up to required applications.

Viton ® (FKM Fluoroelastomer) features a maximum temperature-resistance of 204°C, without sacrificing on the life-span of the actual materials. The Fluoroelastomers typically decompose when exposed to higher temperatures and when they are exposed to heat such as fire they may also release hydrogen fluoride residues that are hazardous.

Viton ® (FKM Fluoroelastomer) is not able to maintain its acceptable performance and flexibility in the fixed application where the temperature falls below “26°C. However, in certain applications Viton ® (FKM Fluoroelastomer) is still able to perform in “40°C temperatures and “15°C to “18°C in specific types of dynamic situations.

Some of the fluorocarbon compounds show an enhanced resistance to acids, temperature extremes, ozone, water, steam and fuels. Viton ® (FKM Fluoroelastomer) is also highly resistance when it comes to:

– Sunlight and oxygen

– Compression

– Phosphate esters, oils, grease, vegetable oil, silicone, and minerals

– Salt solution

– Aromatic hydrocarbons such as toluene and benzene, aliphatic hydrocarbons such as natural gas, propane and butane

– Inflammable hydraulic fuels

– Methanol fuels and chlorinated hydrocarbons

Viton ® (FKM Fluoroelastomer) doesn’t resist ketones and acetones very well. Viton ® (FKM Fluoroelastomer) is also not very compatible with alkalis and ammonia gas-amines, glycol-based brake-fluids, acetic and fomic acids and superheated steam.

Viton ® (FKM Fluoroelastomer) Uses

The Viton ® (FKM Fluoroelastomer) Rubber products offer an array of uses without compromise. These types of elastomers are used more commonly as a gasket material like the ones that seal pumps, valves, leaks, etc.

The Viton ® (FKM Fluoroelastomer) O-rings has for many years been in use for SCUBU diving gear, particularly for the divers that use Nitrox gases, because the Viton ® (FKM Fluoroelastomer) materials are less likely to cause ignition from an oxygen content that is increased in Nitrox. Decay caused from an oxygen content that is increased is also a lot less.

Automotive along with other types of transport-fuel application that are subjected to high concentrations of biodiesel recommend tubing and hoses that are Viton ® (FKM Fluoroelastomer)-lined. Buna and Viton ® (FKM Fluoroelastomer) are elastomers that are the most commonly-used when it comes to automotive sealing.

The Viton ® (FKM Fluoroelastomer) O-rings offers functional characteristics that are similar and provide higher chemical and temperature resistance when compared to the Buna-N seals in engine timing-units in automobiles. Even though the performances of the Viton ® (FKM Fluoroelastomer) O-rings vary significantly, they are all highly compatible with the hydrocarbons.

When Are Viton ® (FKM Fluoroelastomer) Fluoroelastomers Used

When it comes to many automotive applications, Viton ® (FKM Fluoroelastomer) has gone onto establish the latest performance standard when it comes to the most current engine and fuel systems. Viton ® (FKM Fluoroelastomer) offers an improvement in system durability when it comes to extreme temperatures associated with acid condensates, transmission fluids, oils and fuels.

In tough gas and oil down-hole applications, Viton ® (FKM Fluoroelastomer) often assists in extending maintenance intervals along with helping to guard against the failure of seals. Viton ® (FKM Fluoroelastomer) also offers sealing when it comes to extremely high temps in the aggressive fluids used in jet engines. This ensures reliability which serves continuously at temperatures of 204°C.

Heat-resistant properties of Viton ® (FKM Fluoroelastomer) outlast the nitrile rubbers along with other types of general-purpose elastomers. The reliability of this product allows for an extension in service intervals, along with helping to extend maintenance budgets in the way of lowering unscheduled downtime, which includes a number of industries that include:

– Automotive

– Aerospace and aircraft

– Chemical transportation and processing

– Petroleum transportation and refining

– Gas and oil production and exploration

The primary uses of Viton ® (FKM Fluoroelastomer) include caulks, bonded seals, vibration dampeners, coatings, radial-lip seals, expansion joints, O-rings, gaskets, stock sheet and rods, and customized shapes.
