What is the difference between EPDM and FKM?

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.

Are Viton and EPDM the same?

Viton® rubber is a fluoro elastomer, whereas epdm rubber is ethylene-propylene-diene-monomer. The primary differences between Viton® and EPDM is in their chemical resistance and temperature ranges. Both have different properties and applications for general industrial use.

What does FKM stand for material?

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 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.

What rubber is FKM?

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.

Technical Tuesday: What's the Difference Between EPDM, FKM

Is FKM and Viton the same thing?

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 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 the 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 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)

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.

Is FKM a polymer?

FKM - Fluoroelastomers

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 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 an 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.

Are there different types of EPDM?

The three types of EPDM installation are ballasted, fully adhered and mechanically attached.

What is the difference between EPDM and FPM?

FPM is often used in high-temperature applications due to its excellent heat resistance and oxidative stability, whereas EPDM is employed when low temperature leak tightness is required.

What is the difference between EPDM and PTFE?

EPDM is softer and performs better as a sealing material (it conforms better to rough surface finishes). Teflon is stiffer and slicker, therefore it may perform better in a dynamic or abrasive application. Both could care less about sea water in terms of chemical assault or corrosion.

What is an FKM strap?

Quick Release Rubber

FKM rubber is made to stand harsh conditions; it's waterproof, so it is excellent for outdoor use, and that's why FKM rubber straps are so popular among divers and adventurers. Available watch lug options : 20mm, 22mm and 24mm.

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.

What rubber is used for watch straps?

Nowadays, however, the vulcanised nitrile rubber watch strap is one of the most popular and widely used for high-performance applications. As with any rubber, its performance isn't just determined by its type, be it Nitrile Butadiene Rubber (NBR), silicone rubber, polyurethene rubber or PVC rubber.

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.)

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).

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.

How long does a rubber strap last?

Know that rubber watch straps don't have as long as a lifespan as other types of straps and generally need to be replaced every 18 months to two years.

Is fluorocarbon the same as FKM?

Fluorocarbon (or Viton® as it's is more commonly known) is a brand name of DuPont. In situations where both temperatures and the surrounding conditions can be extreme, Fluorocarbon offers excellent performance.
