What is Viton not compatible with?

What is Viton not compatible with?

It is a synthetic rubber that resists many hydrocarbons, biodiesel, and petro chemicals, but is NOT compatible with ketones. Do not use Viton with acetone, esters, amines, organic acids, acetic acid, MEK, ethyl acetate, highly polar chemicals, etc.

Is Viton compatible with hydraulic fluid?

Viton® is compatible with hydrocarbons, lubricating and fuel oil, hydraulic oil, gasoline, kerosene, vegetable oils, alcohol and diluted acids.

Is Viton compatible with r134a?

NBR and Viton were selected because of their poor property stability and performance when exposed to current HFC refrigerants; unlike EPDM which performs very well and is the go-to material for seal material in current HFC-134a automotive compressors.

Is Viton compatible with sodium hydroxide?

How resistant is Viton? Unlike EPDM, Viton has a good resistance to oils, fuels, lubricants, and most mineral acids. It is resistant to most chemicals, but not to for example Acetic acid, Ammonia, Caustic soda, Formic acid and Potassium hydroxide.

Is Viton good for oil?

An exceptionally broad range of chemical resistances make Viton seals a perfect option for most applications involving oils, fuels, and mineral acids, and these seals also boast excellent resistances to oxidation, ozone, UV exposure, weather, fungus, and mold.

Is Viton suitable for oxygen?

Good gasket materials for gaseous oxygen include neoprene, EPDM, silicone, butyl and Viton® (a DuPont brand name for FKM.) Rubber materials such as SBR and natural rubber should be avoided because of their tendency to react with oxygen.

Which hydraulic fluid is often incompatible with rubber seals?

Petroleum oil hydraulic system seals of neoprene or Buna-N are not compatible with Skydrol® and must be replaced with seals of butyl rubber or ethylene-propylene elastoiners.

Can I convert 1234yf to 134a?

You can convert an empty R-1234yf system to R-134a.

Can I use 134a instead of 1234yf?

The answer is yes, it will. This makes it simple. Service shops can stock one product, PN 702, and use it for any vehicle, whether it uses R-134a or R-1234yf.

Is Viton better than 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 harder than Nitrile?

Viton® seals are prone to failure below -15°C in dynamic applications, as they become inflexible and hard. This makes Viton® far superior to Nitrile in these regards. They are also designed to resist most oils and lubricants, more importantly petroleum-based lubricants.

What is the difference between Viton and Buna o rings?

Viton is the choice over Buna for high-temperature applications. Viton seals hold indefinitely at temperatures up to 400°F and can last up to 48 hours at temperatures up to 600°F. Buna is effective to 250°F. Viton offers universal chemical resistance for sealing applications for oils, fuels, and mineral acids.

Are there any chemicals that are not compatible with Viton?

Viton Chemical Compatibility. It is a synthetic rubber that resists many hydrocarbons, biodiesel, and petro chemicals, but is NOT compatible with ketones. Do not use Viton with acetone, esters, amines, organic acids, acetic acid, MEK, ethyl acetate, highly polar chemicals, etc.

What is the chemical compatibility of Viton fluoroelastomer?

Viton® Chemical Compatibility Chart: Check the chemical compatibility of Viton® with various chemicals, solvents, alcohols and other products. A trademark of DuPont, Viton fluoroelastomer in general has a high temperature tolerance and chemical resistance rating.

Which is the best Viton compound for Scorch treatment?

Compounds of Viton that use this cura- tive exhibit fast rates of cure and excellent scorch safety and resistance to compression set. In 1987, an improved bisphenol curative was intro- duced, which was made available in several different precompounds: Viton A-201C, A-202C, A-401C, and A-402C.

What is the chemical compatibility of Tygon tubing?
