What does FKM rubber stand for?

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 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 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.

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.

What is FKM/Viton/Fluoroelastomer? Things you must know about FKM/Fluoroelastomer/Viton?

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 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 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.

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 a silicone?

TYM Seals & Gaskets

TYM has nearly 40 years experience in supplying and manufacturing gaskets and seals made from silicone, FKM fluoroelastomer, neoprene, nitrile and more.

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.

Is FKM vulcanized rubber?

Simply put, vulcanised rubber means that it has been cured to make it both strong and flexible. In chemistry, FKM refers to a material with high chemical and thermal resistance. In other words, these are the characteristics of FKM vulcanised rubber: Robustness (tear and tensile strength)

What type of material is NBR?

NBR is the abbreviation for nitrile butadiene rubber. This is a synthetic rubber that was developed during the 1930s. It is fabricated through the co-polymerization of acrylonitrile (ACN) (polar building block) and 1.3-butadine (nonpolar building block).

What is NBR gasket?

NBR gaskets are made of a rubber also known as Buna-N, which is the most widely used elastomer for seals and gaskets. Its properties provide superior resistance to petroleum-based fluids, hydraulic fluids, gasoline, alkalis and acids.

Is FKM same as 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.

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.

What are the best rubber watch bands?

What is an FKM watch strap?

FKM - Fluoroelastomer, which is a class of man-made rubber of great density, made to stand harsh conditions, such as high temperature and chemicals, etc. This 20mm Quick Release Watch Band is waterproof, great for outdoor use and that's why FKM rubber strap is highly popular among divers and adventurers.

Why does rubber smell like vanilla?

Momentum's rubber straps are made for us by a family-owned company in Italy that has been making high quality rubber straps for generations. They discovered that adding a small amount of vanilla essence to the rubber compound “cancels out” the pungent natural rubber smell.

What is the difference between FKM and FFKM?

The key difference between FKM and FFKM is that FKM offers a less degree of versatility compared to FFKM. FKM stands for fluoroelastomer whereas FFKM stands for perfluoroelastomer. FKM and FFKM are two types of elastomer materials. Therefore, these are two types of polymers having elastic properties.

Which is better Viton or PTFE?

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.

What is Viton rubber used for?

Viton® is a brand name of DuPont for its synthetic rubber and fluoropolymer elastomer, commonly used in O-rings and other moulded or extruded products.

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.

Solvay's Tecnoflon® FKM grades are REACH-compliant and select grades have been submitted for ISO 10993 biocompatibility testing.

What is NBR in O-rings?

Nitrile rubber (NBR) o-rings, also known as Buna-N, are one of the most commonly used sealing elastomers due to resistance to petroleum-based fuels and lubricants and its relatively low price. Nitrile elastomers are copolymers of acrylonitrile and butadiene. There are a number of common variations of nitrile compounds.
