Is Viton compatible with caustic soda?
Unlike EPDM, Viton has good resistance to oils, fuels, lubricants, and most mineral acids. It is resistant to most chemicals, but not too for example Acetic acid, Ammonia, Caustic soda, Formic acid, and Potassium hydroxide.
What is Viton not compatible with?
Do not use Viton with acetone, esters, amines, organic acids, acetic acid, MEK, ethyl acetate, highly polar chemicals, etc. Viton is generally serviceable in dynamic applications to temperatures of -18 to -23 °C.
Is Viton resistant to sulfuric acid?
Viton G is Alfa Laval’s recommended material for hot concentrated sulphuric acid. The material Vton G contains substantially more fluorine than other grades which improves its resistance to hot concentrated sulphuric acid.
Are Viton seals solvent resistant?
Broad Chemical Compatibility
Because Viton FKM Fluorocarbon is compatible with a very wide range of chemicals, fuels and solvents, it can reduce costs through extended service life and reduce unscheduled downtime for seals and components.
Is Viton good for solvents?
The Viton® A is a fluoroelastomer dipolymer comprised of vinylidene fluoride and hexafluropropylene. Provides good chemical resistance to petroleum products and solvents.
What is the difference between Viton and EPDM?
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 is difference between Nitrile and Viton?
Environmental Properties: Viton® O-rings and seals have a wide range of chemical resistance (involving mineral acids, fuels, and oils) and this material is also highly resistant to oxidation, UV exposure, fungus, weather, ozone, and mould. This makes Viton® far superior to Nitrile in these regards.
Is Viton resistant to ethanol?
With exceptional chemical resistance, Viton® offers swell resistance in high octane and oxygenated fuel blends. This gives Viton® superior performance abilities in Ethanol/Methanol blended gasoline applications.
Is Viton compatible with amines?
The Viton® A is a fluoroelastomer dipolymer comprised of vinylidene fluoride and hexafluropropylene. Provides good chemical resistance to petroleum products and solvents. Avoid polar solvents, amines, anhydrous ammonia, hydrazine and hot acids.
Which is better nitrile or Viton?
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.
Does acetone dissolve Viton?
1) Viton is soluble in acetone .
Is EPDM chemical resistance?
EPDM is a non-toxic, FDA-approved synthetic material that has gained widespread industry popularity for its excellent resistance and chemical compatibility properties.
Is PTFE better than Viton?
Oil Resistance: Poor
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.
Which is better Viton or EPDM?
Temperature – Viton® temperature resistance ranges from -20°C to 210°C, while EPDM temperature resistance ranges from -45°C to 145° This means that both are excellent for extreme temperatures, but EPDM has a slight edge in colder temperatures, while Viton® is better for heat resistance at higher temperatures.
Is Viton resistant to methanol?
Although parts made from Viton™ A have served the chemical processing industry well for many years, improved seal performance may be possible with specialty types of Viton™. For example, Viton™ A is rated D for service in methanol at 23ºC because of volume swell, but Viton™ F, GFLT-S and Extreme™ ETP-S are rated A.
Is Viton resistant to ammonia?
What is difference between nitrile and Viton?
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.
Is Viton better than EPDM?
Is Viton the same as FKM?
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 EPDM and Viton?
What is the difference between PTFE and EPDM?
RE: PTFE vs EPDM
EPDM is softer and makes a better sealing material (conforms better to rough surface finishes). Teflon is stiffer and slicker, which might hold up better in a dynamic or abrasive application. Both could care less about sea water from a chemical attack/corrosion standpoint.
Are Viton and FKM the same?
Which is better PTFE or Viton?
