What does FKM stand for material?

Fluro-Elastomer
FKM is the American standard ASTM short form name for Fluro-Elastomer. It is the designation for around 80% of Fluoro-Elastomers defined by ASTM D1418.

Is FKM plastic or rubber?

Unsourced material may be challenged and removed. 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.

What is Viton FKM?

FKM (FPM, Viton®, Fluorel®) resist mineral oils and greases, aliphatic, aromatic and also special chlorinated hydrocarbons, petrol, diesel fuels, silicone oils and greases. It is suitable for high vacuum applications.

Is FKM 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.

Is FKM same as PTFE?

FKM offers greater temperature resistance but falls short of PTFE’s properties in terms of chemical resistance. While PTFE is slightly less thermally resistant but offers much in the way of non-adhesive properties.

Is FKM a Teflon?

Fluoroelastomer (FKM) rubber is a thermoset elastomer while Polytetrafluoroethylene (PTFE) is a thermoplastic. Both are fluorinated materials comprising of carbon atoms surrounded by fluorine atoms, which gives them incredible chemical resistance.

Are FKM and Viton the same?

What is Viton E?

Viton™ E-45 and Viton™ E-60 are low- to moderate- viscosity polymers of the “A-family” of Chemours Viton™ fluoroelastomers, modified to provide improved compression set resistance. Viton™ E-45 is used alone or in blends with other types of Viton™ fluoroelastomers to improve mold flow and hot demolding tear strength.

Is FKM rubber vulcanized?

If you compare FKM and vulcanized rubber, FKM is like the superhero, synthesized cousin to the latter. Vulcanized rubber is made by mixing natural rubber with additives (such as sulfur) in the process called vulcanization, which makes the material stronger and more flexible.

What is the difference between Viton and Viton A?

Although Viton® A has higher thermal stability than Viton® B, it is typically used in applications where high surface pressures or low temperatures are present.

Is FKM and Viton the same?

What is FKM polymer?

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 Viton and FKM the same?

Viton® is a trademark of a synthetic rubber and fluoropolymer elastomer commonly used in the manufacture of O-Rings. The name is a trademark registered by The Chemours Company and its international abbreviation is FPM (DIN/ISO denomination) or FKM (ASTM).

Is FKM a silicone?

FKM is a highly resilient form of synthetic rubber. Although its official name is Fluoro-Elastomer, it is usually referred to as FKM rubber after a popular brand which manufactures it. The hard-wearing qualities of FKM make it very popular in the oil and gas industries.
