What does FKM stand for rubber?

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. VITON™ is a registered trademark of Du Pont performance elastomers, the original developers of the rubber.

Is FKM better than EPDM?

EPDM (EP, EPR, Ethylene-Propylene Rubber) Both materials are well suited for use in the -30 to 150°C range. FKM has an advantage in lower temperatures and EPDM has an advantage in higher temperatures.

Is FKM plastic or rubber?

FKM is a family of fluorocarbon-based fluoroelastomer materials defined by the ASTM International standard D1418, while it is called FPM by ISO 1629 (both first ed. 1995 and ed. 2013). It is commonly called fluorine rubber or fluoro-rubber. All FKMs contain vinylidene fluoride as a monomer.

Is FKM rubber good?

FKM is of high value in use as a class of synthetic rubber which provides extraordinary levels of resistance to chemicals, oil and heat. This type of rubber can be fabricated into seals, o-rings, and hoses for a variety of high performance applications in the automotive, aerospace, and petrochemical industries.

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.

What is the difference between FKM and NBR?

Standard Viton® / FKM vs Standard Nitrile Standard Viton®/FKM compounds can provide continuous sealing at temperatures up to approximately +205°C. Standard NBR on the other hand is only effective for continuous sealing at temperatures up to +110°C (with short term sealing at 130°C.)

Is FKM rubber soft?

For those who don’t know, FKM stands for Fluoroelastomer, which is a class of man-made rubber of great density but soft in touch, made to stand harsh conditions, such as high temperature, chemicals etc.

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.

Is FKM a vulcanized rubber?

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.
