Difference
between Teflonâ, PTFE & FEP Cannula / Catheter tubing.
Teflonâ
is the brand name of Dupont for its range of Fluro Polymers
– PTFE (Poly Tetra Fluro Ethylene) & FEP (Fluorinated
Ethylene). PTFE is relatively superior to FEP in having a
lower coefficient of friction which is an important factor to
minimise trauma to the blood vessel/Tissue for enabling smooth
cannulation.
