Fluoroelastomer (Viton/FKM) have superior sealing performance in a wide variety of aggressive applications. Major uses include stock sheets and rods, gaskets, bonded seals, radial lip seals, O-rings, piston seals, vibration dampeners, expansion joints, and custom shapes.

Changzhou Meridian can provide you these parts using raw gums FKM26 (eqv Viton A) and FKM246 (eqv Viton B) from China local supplier. For other choice, we provide these parts using Genuine Dupont viton A, viton B, viton F, such as A-361C, A401C, B-601C, GF-600S, GFLT-600S and etc raw gums. For genuine Dupont viton A, viton B, viton F products, we have COA from Dupont.

We also provide these parts using Solvay, and Daikin raw gums, and offer bisphenol AF or peroxide vulcanization products as requirement. 

The other advantage and technical specification for Fluorine rubber (FKM) are as following for your reference.
Exceptional performance
Fluorine rubber (FKM) has delivered a combination of high-temperature performance and exceptional chemical resistance. Its dynamic characteristics give critical seals and parts exceptional performance and longer life in aggressive environments.

Reduce lifetime costs and cut unscheduled downtime
Fluorine rubber (FKM) far outlasts nitrile rubber and other general-purpose elastomers. It allows you to extend service intervals and stretch maintenance budgets because the increased reliability of Fluorine rubber (FKM) reduces unscheduled downtime.

Increase temperature capability
In many applications, rubber parts are stressed by accidental temperature excursions as well as increases in operating temperatures designed to increase production. In some situations, Fluorine rubber (FKM) can serve continuously at 204 ºC, even after excursions to 315 ºC. Certain types of Fluorine rubber (FKM) can perform equally well at temperatures as low as –40 ºC.

Stand up to aggressive fluids
Fluorine rubber (FKM) performs well in a wide range of aggressive fluid environments. Systems using Fluorine rubber (FKM) can tolerate changes in fluids and have more versatility for broader application.

Comply with tougher regulations
Environmental regulations have raised the stakes for leaks, spills and emissions. The reliable sealing performance of Fluorine rubber (FKM) helps guard against these problems to improve plant and automotive operations.

A tough contender
Fluorine rubber (FKM) are compatible with many important chemical media. The capabilities of other elastomers shown for comparison can be helpful when you’re considering changing materials to increase reliability or accommodate more severe operating conditions.
FKM also offers mechanical ruggedness so that seals and components resist damage during installation and use. Basic mechanical property data listed below demonstrate how FKM compares favorably with other elastomers in tensile strength, range of hardness, and resistance to compression set.

Superior thermal stability
Resisting damage from thermal upsets is an important deterrent against failure for seals and other components. Fluorine rubber (FKM) resist hardening and embrittlement for >10,000 hours in air up to 204 oC, and endure thermal excursions to 315 oC. With the high-temperature capability of Fluorine rubber (FKM), some users can increase operating temperatures to improve productivity or gain other advantages.
Fluorine rubber (FKM) also delivers at low temperatures. Dynamic seal applications for Fluorine rubber (FKM) have been successful at –40 oC
More importantly, Fluorine rubber (FKM) exhibits good resistance to fluids at elevated temperatures. Figure 2 compares the performance of FKM. and other elastomers in a standard SAE/ASTM test that measures volume swell in hot oil. A swell of more that 30% is usually unacceptable.

Broad chemical compatibility
Because Fluorine rubber (FKM) is compatible with an exceptional range of chemicals, fuels and solvents, it can reduce costs through extended service life and reduce unscheduled downtime for seals and components. Broad compatibility also increases product versatility to extend applications. 

Permeation resistance to reduce emissions
In addition to its characteristic resistance to aggressive fluids and high temperature, Fluorine rubber (FKM) is often specified for its excellent resistance to permeation. In automotive, chemical processing and other industries, Fluorine rubber (FKM) helps minimize fugitive emissions to meet Clean Air Act requirements.
