What is fluoroelastomer used for?

What is fluoroelastomer used for?

Fluoroelastomers are used mainly in seals and barrier layers subjected to environments too severe for other elastomers. Fluoroelastomer components have long service life at temperatures above 150°C (302°F), and some specialty perfluoroelastomer parts can withstand sustained temperatures above 300°C (572°F).

Is fluoroelastomer the same as Viton?

Fluoro-Elastomer is usually referred to as FKM FPM or as VITON™ after the popular brand which produces it. You may see this rubber listed in different places with these different names, but they are all one and the same.

What is fluoroelastomer rubber?

Fluoroelastomer, also called fluorocarbon elastomer, any of a number of synthetic rubbers made by copolymerizing various combinations of vinylidene fluoride (CH2=CF2), hexafluoropropylene (CF2=CFCF3), chlorotrifluoroethylene (CF2=CFCl), and tetrafluoroethylene (C2=F4).

Is fluoroelastomer silicone?

As nouns the difference between silicone and fluoroelastomer is that silicone is while fluoroelastomer is (organic chemistry) any of a range of partially fluorinated polymers or copolymers that are chemically and thermally stable elastomers.

Is Viton better than nitrile?

General Suitability: Viton® is best suited for diverse sealing jobs that require high temperature and chemical resistance. This makes Viton® far superior to Nitrile in these regards. They are also designed to resist most oils and lubricants, more importantly petroleum-based lubricants.

What is difference between FKM and 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. The first commercially available FFKM seal was produced in the late 1960s.

Is Viton expensive?

A Viton™ o ring will tend to be significantly more expensive than the equivalent nitrile component. This is because it simply does the job where other products cannot.

What material is fluoroelastomer?

synthetic rubber
A fluoroelastomer is a fluorocarbon-based synthetic rubber. Fluroelastomers generally have wide chemical resistance.

Is Viton harder than nitrile?

Viton® seals are prone to failure below -15°C in dynamic applications, as they become inflexible and hard. This makes Viton® far superior to Nitrile in these regards. They are also designed to resist most oils and lubricants, more importantly petroleum-based lubricants.

Are Viton O-rings black?

This O-ring is made of black Viton and has a durometer of 90A, a round cross-section, and can be used across a wide temperature range (-15 degrees F /-26 degrees C to 400 degrees F/ 205 degrees C).

What kind of material is FKM?

FKM is the ASTM designation for a class of fluorinated, carbon-based synthetic rubber, commonly known as fluoroelastomer. FKM has impressive heat resistance, allowing FKM seals to withstand temperatures greater than 200°C.

Are there any toxic side effects of fluoroelastomers?

Fluoroelastomers are first compounded into required formulations with a variety of ingredients; some of them may be reactive and/or toxic. In mixing and subsequent processing into finished products, some components of the formulations may generate toxic byproducts.

What happens if you get in contact with hydrogen fluoride?

Depending on the concentration of the chemical and the length of time of exposure, skin contact with hydrogen fluoride may cause severe pain at the point of contact; a rash; and deep, slow-healing burns.

What is the chemical compatibility of Viton fluoroelastomer?

Viton® Chemical Compatibility Chart: Check the chemical compatibility of Viton® with various chemicals, solvents, alcohols and other products. A trademark of DuPont, Viton fluoroelastomer in general has a high temperature tolerance and chemical resistance rating.

Do you know what type of fluoroelastomer you are using?

Care should be taken by users of parts to assure that the proper fluoroelastomer composition is chosen for the application. This is not always easy to determine, since many parts’ suppliers may not disclose the type of fluoroelastomer used.
