Notes

PTFE (Polytetrafluoroethylene) a fluorocarbon-based polymer, is a resin supplied in powdered form, which is mixed, preformed, and extruded into a paste, and then finally tubing. PTFE tubing can be used in a wide variety of applications due to its high chemical resistance, high and low temperature capability, resistance to weathering, electrical and thermal insulation, gas and vapor permeability properties and lowest coefficient of friction of any solid material. The tubing is translucent white in color.

 

FEP (Fluorinated Ethylene Propylene) resin is pelletized for its hot-melt extrusion process. FEP tubing is known for its gas and vapor permeability properties and excellent UV transmission ratings. While very similar in composition to PTFE, there are a few notable differences. FEP has a lower heat shrink temperature and is clearer and more flexible than PTFE.

 

PFA (Perfluoroalkoxy) resin, like FEP, belongs to a class of melt-processible fluoroplastics. PFA tubing is also known for its gas and vapor permeability properties and excellent UV transmission ratings. It is similar in composition to FEP but has better heat resistance and a smoother surface. It, too, is clearer and more flexible than PTFE.

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.

 

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 — call for details.
