What is PTFE not compatible with?

PTFE is affected by some alkali metals (molten or in solution) and rare fluorinated compounds at high temperatures and/or pressures. Some organic and halogenated solvents are absorbed causing minor dimensional changes but these effects are physical and also reversible.

Is Teflon and PTFE the same thing?

Chemours trademarked the name Teflon in 1945 and began selling products treated with this non-stick, heat resistant material in 1946. Teflon is a synthetic polymer containing carbon and fluorine called polytetrafluoroethylene. That’s right, Teflon is PTFE but by another name.

Is Teflon compatible with acetone?

PTFE Chemical Compatibility Chart: Polytetrafluoroethylene is very non-reactive and ideal for use with most chemicals….PTFE and Teflon Chemical Compatibility Chart.

Chemical Compatibility
Acetic Acid, Glacial A-Excellent
Acetic Anhydride A-Excellent
Acetone A-Excellent
Acetyl Bromide A-Excellent

Is PTFE compatible with ethanol?

Teflon® (PTFE) is one of the most chemically resistant plastics and has excellent chemical compatibility with 200 proof ethanol.

Does acid react with Teflon?

For having used “sulfonitric acid” (sulfuric and nitric acids mixture) for at least 2 decades, PTFE is definitely stable to such a mixture.

Which is better PTFE or Teflon?

Essentially, the only difference lies in the name. PTFE is the shortened name of the chemical polytetrafluoroethylene, and Teflon is the trade name of the same polymer. If you are looking for a highly flexible, non-stick material that is chemical, electrical and thermal resistant, look no further than PTFE.

What plastics are acid resistant?

Polypropylene – Polypropylene is a thermoplastic polymer that’s rugged and resistant to many acids. It can also function as both a plastic and a fiber, and because of that has one of the largest varieties of applications of all plastics. The fact that it’s relatively cheap to produce also doesn’t hurt.

Does Teflon react with acid?

PTFE (or Teflon™) – PTFE, also commonly known as Teflon™, is one of the most acid resistant materials available and is commonly used in chemical and pharmaceutical lab applications.

Is Teflon compatible with oxygen?

Liquid oxygen can only be sealed by materials capable of withstanding very low temperatures. PTFE gaskets are a good choice as is FFKM (perfluoroelastomers) gasket material. Good gasket materials for gaseous oxygen include neoprene, EPDM, silicone, butyl and Viton® (a DuPont brand name for FKM.)
