What is AFLAS material?

What is AFLAS material?

AFLAS® is unique fluoroelastomer that has superior amine resistance and electrical insulation compared to conventional fluoroelastomers. AFLAS® is highly suitable for critical applications where exceptional reliability is required.

Is Aflas the same as PTFE?

Tetrafluoroethylene propylene (FEPM, TFE/P), also known as Aflas®, is a partially fluorinated elastomeric polymer consisting of propylene and tetrafluoroethylene repeat units. Its thermo-physical properties are similar to those of polytetrafluoroethylene (PTFE) but somewhat inferior.

Is Aflas an FKM?

Both materials are well suited for use in the -10 to 205°C range. Aflas® has an advantage in lower temperatures and FKM has an advantage in higher temperatures.

What is a TFE O ring?

Tetrafluoroethylene Propylene (TFE/P) O-Rings Material Description: Tetrafluoroethylene Propylene (TFE/P) o-rings are a copolymer made up of tetrafluoroethylene (TFE) and propylene. TFE/P has excellent resistance to ozone and weathering along with a wide range of chemicals, including acid, base, and steam.

Is Aflas an elastomer?

Description: Aflas® material is an elastomeric based flouorubber, a copolymer of tetrafluroethlene and propylene. This elastomer offers excellent chemical resistance qualities, with serviceability in the temperatures up to 550 degrees F depending on environment.

What temperature can Viton withstand?

Viton seals provide an indefinite seal for temperatures up to 400°F, and for temperatures up to 600°F they offer an excellent seal for more than 48 hours. Buna on the other hand is only effective up to 250°F.

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 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.

What is Aflas rubber?

Aflas®, also known as TFE/P rubber, is a copolymer of tetrafluoroethylene and propylene with a fluorine content of app. 54%. It can handle high temperature, chemic and steam. Aflas® works perfectly together with water, steam, bases, and caustics.

Is PTFE safe for O-rings?

If you are concerned about the compatibility of your O-Ring seal with a sealed medium or sealing over a wide temperature range, PTFE is one of the safest choices you can make. PTFE O-Rings do not have the compliance of rubber O-rings.

Which is better PTFE or Viton?

What is the highest temperature o-ring?

The general accepted range for o-ring use is approximately -75 degrees and 620 degrees Fahrenheit. This wide spectrum is due to the materials from which o-rings can be manufactured.

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. It’s a dead heat!

Is FKM and Viton the same?

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.

What are the disadvantages of PTFE?

Depending on the application, the following disadvantages can rule out the selection of PTFE:

• Price – it is not a low-cost polymer.
• Production sizes – it is not easy to mass produce.
• It cannot be cemented.
• It can change shape under pressure.
• It is unweldable.

What temperature do O-rings melt?

O-Ring Material Temperature Guide

How hot can an o-ring get?

Is FKM 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. Originally developed by Du Pont, it is produced by a number of companies around the world.

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 PTFE flammable?

Polytetrafluoroethylene (PTFE) is a totally fluorinated polymer which is white, semi-opaque, and semi-crystalline. It has excellent chemical resistance, is unaffected by nearly all chemicals, and has a very high oxygen index (i.e. is inherently non-flammable).

How much heat can an o-ring handle?

Are O-rings heat resistant?

O-Rings for Automotive Oils, Fuels And Gases
ACM O-rings have the ability to withstand temperatures of 150°C. Hydrogenated Nitrile or HNBR has a top temperature of 140°C and again, this is compatible with automotive fuels, oils and gases although it is not suitable for use with chlorinated hydrocarbons or strong acids.

Is FKM the same as Viton?

Is PTFE heat resistant?

Teflon® (PTFE) – Teflon® is most widely known for its non-stick properties as it has one of the lowest coefficients of friction against any solid known to man. But it also has a large operating temperature range, with enough thermal stability to be used between -328ºF and +500ºF without degrading.

What temperature can PTFE withstand?

Tensile and compressive properties of PTFE
PTFE, however, can be used continuously at temperatures up to 260°C, while possessing still a certain compressive plasticity at temperatures near to the absolute Zero.
