Item # 310 0552, Fluoropolymer Tubing (PTFE, FEP & PFA)

List Price QUOTE

  • Chemically inert; low permeability
  • Manufactured from FDA-sanctioned ingredients for use with food contact surfaces
  • Lowest coefficient of friction of any solid material
  • Widest service temperature of any plastic tubing (-275ºF to 500ºF)
  • Excellent electrical and weathering properties; non-flammable
  • Made without plasticizer which can leach into critical streams
  • Ultra-high-purity grades available for the semiconductor industry.
Notes

Almost totally inert, FLUOROPOLYMER tubing 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 and PFA are clearer and can be heat sealed and heat bonded.

Permanent color striping, etching, and longer-than-listed lengths are available through minimum order. Polyethylene-jacketed, thin-wall fluoropolymer tubing, for low-cost purity, is also available through minimum order.

What is it?

PTFE (Polytetrafluoroethylene)
resin is supplied in powdered form, which is mixed, preformed, and extruded into a paste, and then finally tubing. It is translucent white in color.

FEP (Fluorinated Ethylene Propylene) resin is pelletized for its hot-melt extrusion process and is a clear tubing.

PFA (Perfluoroalkoxy) resin is also a pelletized product which is hot melt extruded. It, too, is clear.
