Is Teflon compatible with methanol?
Virgin Teflon FEP is considered an excellent choice for flange gaskets in methanol service. majority of chemicals that attack other elastomers, and have good long-term high temperature compression set resistance.
Is PTFE resistant to methanol?
Actual properties may change due to processing method, compound type, extruded dimensions and other variables. It is the user’s responsibility to evaluate and fully test the suitability of the product for their specific application….Chart codes.

What chemicals does PTFE resist?
The chemical resistance of Virgin PTFE is excellent. It is stable in most aggressive and corrosive media, exceptions being liquid or dissolved alkali metals, flourine and other extremely potent oxidisers.
What is the difference between Pctfe and PTFE?
PCTFE is a homopolymer of chlorotrifluoroethylene (CTFE), whereas PTFE is a homopolymer of tetrafluoroethylene. PCTFE is a harder and stronger polymer, with better mechanical properties than PTFE. Though PCTFE has excellent chemical resistance, it is still less than that of PTFE.
Does nitric 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.
What plastic can withstand acid?
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.
Is PTFE suitable for HCL?
PTFE extruded tubing, and PTFE shrink tubing, are used by our customers in various industries and in different applications, which may require resistance to specific chemicals….PTFE Chemical Resistance Chart.

Is PTFE acid resistant?
1. 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.
What can dissolve PTFE?
The chemical resistance of PTFE is outstanding, there are no solvents which could dissolve PTFE at room temperature and the surface of PTFE at room temperature is affected only by molten alkali and fluorine in some cases.
Is PTFE compatible with chlorine?
PTFE extruded tubing, and PTFE shrink tubing, are used by our customers in various industries and in different applications, which may require resistance to specific chemicals….PTFE Chemical Resistance Chart.

What does Pctfe stand for?
Polychlorotrifluoroethylene
PCTFE (Polychlorotrifluoroethylene) is a homopolymer of Chlorotrifluoroethylene. The replacement of a single fluorine atom on the carbon backbone with a chlorine atom, changes the properties of the fluoropolymer to allow melt processing.
What is Kel F material?
Kel-F® (PolyChloroTriFluoroEthylene) is a fluorocarbon based polymer and is frequently abbreviated as PCTFE. PCTFE combines physical and mechanical properties, non-flammability, chemical resistance, near zero moisture absorption and excellent electrical properties not found in any other thermoplastic fluropolymer.
