When it comes to high-performance fluorinated elastomers, VITON and FKM are two terms that frequently come up in discussions.
What is FKM?

FKM stands for fluoroelastomers, a type of synthetic rubber designed for high-temperature and chemical-resistant applications. Fluoroelastomers are known for their outstanding properties, including excellent resistance to heat, chemicals, and oil, as well as low permeability to gases. These properties make FKM materials highly desirable in industries such as automotive, aerospace, oil and gas, and chemical processing.
What is VITON?

VITON is a brand name registered by DuPont (now Chemours) for its range of FKM products.
The Relationship Between VITON and FKM?
The relationship between VITON and FKM is straightforward: VITON is a brand of FKM. VITON specifies the product line developed by DuPont (now Chemours). Therefore, all VITON products are FKMs, but not all FKMs are VITON.
Key Properties of VITON and FKM:
Both VITON and other FKM materials share several key properties:
– Heat Resistance: Capable of withstanding temperatures up to 250°C (482°F) and higher for short periods.
– Chemical Resistance: Excellent resistance to a wide range of chemicals, including oils, fuels, lubricants, and most mineral acids. We recommend a easy-to-use website to search for the chemical resistance properties of different rubber materials:https://eriks.com/en/tools/rubber-chemical-resistance-guide
– Durability: High resistance to weathering, ozone, and aging, ensuring long-term performance.
– Low Permeability: Low gas permeability, making them suitable for sealing applications.
Typical applications of VITON and FKM:
| Application Area | Specific Applications | Key Features of VITON and FKM |
|---|---|---|
| Automotive Industry | – Seals and Gaskets – O-rings | – High temperature resistance – Fuel resistance – Engine oil resistance – Transmission oil resistance |
| Oil and Gas Industry | – Sealing Solutions – Valve Seals and O-rings | – High pressure resistance – Harsh chemical resistance – Preventing leaks |
| Chemical Processing | – Pump and Valve Seals – Hose Linings and Diaphragms | – Resistance to solvents, acids, and caustics – Reliable chemical transfer |
| Industrial Applications | – Compressor Seals – Gasket Materials | – Efficient operation of compressors – Durability – High-temperature operation |

We, OBT could provide different type of FKM rubber which could cover most of the application. Besides the normal performance FKM material, we have also developed low temperature FKM, conductive FKM and FKM rubber with high fluorine content for better chemical resistance. We could also provide rapid tooling development and competitive cost.
