Is FKM the same as Viton?
These rubber compounds give exceptional heat resistance with compatibility across many fluids or chemical exposures. The most commonly known name for these compounds is “Viton,”™ which has become the generic name for all FKM polymers and rubber compounds.
What does FKM material mean?
FKM is a family of fluorocarbon-based fluoroelastomer materials defined by ASTM International standard D1418, and ISO standard 1629. It is commonly called fluorine rubber or fluoro-rubber. All FKMs contain vinylidene fluoride as a monomer.
Is Viton the same as Teflon?
Viton vs Teflon (PTFE) – Viton offers a greater temperature resistance but falls short of Teflons(PTFE) chemical resistance. Also, Teflon is slightly less thermally resistant but offers much more in the way of non-adhesive properties.
Is Viton an FKM or FFKM?
Both materials are well suited for use in the -15 to 205°C range. FKM has an advantage in lower temperatures and FFKM has an advantage in higher temperatures. Marco offers specific compound formulations extending these ranges even futher as can be seen in the following compound comparison chart.
Is FKM and FPM the same?
So what’s the difference between FPM and FKM? FPM is the international designation to ISO – whereas FKM is the ASTM abbreviation. Both of these designations stand for the same base material : Fluoro Rubber.
What is FKM full form?
Properties. Fluoroelastomers or Fluorocarbons (FKM), also known as Viton®, are highly fluorinated polymers that are suitable for continuous use at elevated temperatures. Various grades are available, including copolymer and terpolymers.
Is FPM and Viton the same?
FKM / FPM / Viton® The terms FKM, FPM and Viton® are all different designations that stand for the same base material, which is fluoro rubber.
Is FKM the same as FFKM?
What is FFKM? FFKM, or perfluoroelastomer, contains higher amounts of fluorine than standard FKM, and features higher temperature ratings, up to approximately 325°C. FFKM also has improved chemical resistance, with nearly universal chemical compatibility.
Is FKM a nitrile?
Nitrile functions well in applications that have limited temperature and resistance requirements. Viton®/FKM O-rings are very versatile, and feature in many different automotive, appliance and chemical processing industries. Click here to see our range of Nitrile compounds.
What is FKM guideline?
The FKM-guideline describes analytical static and fatigue strength assessments procedures of components made of steel, casted iron and aluminum. Base material can be investigated as well as welded structures. It includes different stress concepts (nominal, structural hot spot and local notch stress).
Is FKM an FPM?
The terms FKM, FPM and Viton® are all different designations that stand for the same base material, which is fluoro rubber. FKM is the abbreviation according to the ASTM, FPM is the short form for the fluoroelastomer category according to DIN/ISO and Viton® is the registered trademark of DuPont Performance Elastomers.
