What is fluorocarbon elastomer?

Fluorocarbon elastomers are specialty polymers that possess excellent resistance to elevated temperatures and aggressive chemical media. The products described in this paper are based on Viton polymer produced by DuPont Performance Elastomers and Fluorel polymer produced by Dyneon 3M Company.

What is fluorocarbon material?

Fluorocarbon elastomers are highly fluorinated, carbon backboned polymers used in applications to resist harsh chemical and ozone attack with a thermal stability to 500°F (262°C). The fluorine on the elastomer backbone provides the relative inertness of FKM elastomer. …

Is fluorocarbon plastic or rubber?

Fluorocarbon is an elastomers based on fluororubber (FPM, FKM), also known as VITON (registered trade name of Du Pont), which can be used for U-cups, lip seals, packings, wipers and special seals.

What is the difference between FPM and FKM?

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.

Is fluorocarbon the same as Viton?

Viton® is the brand name for fluorocarbon rubber polymers of the Chemours Company. This type of polymer is used extensively by ERIKS, however we do not claim or promote the use of any specific brands of polymers in our compounds.

Which is better Viton or Buna?

While both Viton and Buna seals both serve as great sealing options at moderate temperatures, Viton is far superior to Buna for high temperature applications. 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 48 hours.

What is the main use of fluorocarbon?

The main applications of the fluorocarbons are as refrigerants, blowing agents for insulation plastic foams, working fluids for Organic Rankine Cycle systems, fire extinguishants and propellants for metered dose inhalers (MDIs) and technical aerosols, solvents and feedstocks.

What is fluorocarbon used for?

Comments: Fluorocarbon makes up just over a quarter of the fishing line market. It excels in clear water applications and its low stretch and greater durability make it popular for hard hook sets and fishing in cover.

Which of the most commonly used fluorocarbon polymer?

The most widely used fluorocarbon polymer is polytetrafluoroethylene, a high-melting nonstick plastic commonly known by the trademark Teflon.

What is difference between FKM and Viton?

FKM is the American standard ASTM short form name for Fluro-Elastomer. VITON™ is a registered trademark of Du Pont performance elastomers, the original developers of the rubber. However, the Viton is also used as a general name for the material, no matter who the manufacturer is.

Is polyethylene an elastomer?

In high-density polyethylene, for example, the long sequences of ethylene units that make up the polymer spontaneously crystallize at temperatures below about 130 °C (265 °F), so that, at normal temperatures, polyethylene is a partially crystalline plastic solid. Polymers that can do so are called elastomers.

What is an FKM O ring?

FPM is the ISO designation, FKM is the ASTM designation. All of the designations stand for one single base material, which is fluoro rubber. This rubber is used in applications that need O-rings that are resistant to high temperatures and chemical attacks.

What does fluoroelastomer mean?

Fluoroelastomer meaning (organic chemistry) Any of a range of partially fluorinated polymers or copolymers that are chemically and thermally stable elastomers.

Fluorocarbon. Fluorocarbons can be perfluoroalkanes, fluoroalkenes and fluoroalkynes and perfluoroaromatic compounds. Fluorocarbons and their derivatives are used as fluoropolymers, refrigerants, solvents, and anesthetics .

Is PTFE a fluorocarbon?

PTFE is a fluorocarbon solid, as it is a high-molecular-weight compound consisting wholly of carbon and fluorine . PTFE is hydrophobic: neither water nor water-containing substances wet PTFE, as fluorocarbons demonstrate mitigated London dispersion forces due to the high electronegativity of fluorine.

What is fluoroelastomer material?

Fluoroelastomer is a fluorinated carbon based rubber material which is mostly used on pressure measurement equipment to seal joints between components which are either pressurised or water-tight.
