Notes
Almost totally inert, Fluoropolymer can be used with virtually all industrial solvents, chemicals, and corrosive materials, even at elevated temperatures. It does, however, react with fluorine, molten sodium hydroxide, and molten alkali metals.
Fluoropolymer Tubing can be steam or chemically sterilized in-line with any industrial cleaner, solvent, or sterilizing method.
Fluoropolymer's non-stick property allows transport of viscous, sticky materials without line clogging. It also offers outstanding aging resistance.
PTFE's translucent white color will vary naturally from lot to lot, however, the quality and physical properties do not change. FEP & PFA are clearer and can be heat sealed and heat bonded.
Custom sizes, colors, and permanent color striping, repetitive cutting, etching, and longer-than-listed lengths are also available.
Polyethylene-jacketed, thin-wall fluoropolymer tubing, for low-cost purity, is also available through minimum order -- call for details. Samples of stock material are available upon request.
