Tefflon Tubing
What’s the difference?
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 large variety of applications due to its high chemical resistance, high and low temperature
capability, resistance to weathering, electrical and thermal insulation, 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.
