A Fluoro polymer is an organic compound consisting of fluorine and carbon atoms but can also contain oxygen or hydrogen. The atoms are held together by bonds to form monomers such as tetra fluorethylene (TFE). When the monomer is polymerized they form into long chains to which TFE becomes polytetrafluoroethylene (PTFE). Fluoro polymers can be either fully fluorinated or partially fluorinated.
1. FULLY FLUORINATED
A. PTFE (POLYTETRAFLUOROETHYLENE)
B. PFA (PERFLUOROALKOXY)
C. FEP (FLUORINATED ETHYLENE PROPYLENE)
2. PARTIALLY FLUORINATED
A. ETFE (ETHYLENE TETRAFLUOROETHYLENE POLYMER)
B. ECTFE (ETHYLENE CHLOROTRIFLUORO ETHYLENE POLYMER)
C. PVDF ( POLY VINYLIDENE FLUORIDE)
PTFE AT GLANCE
PTFE As you can see by the picture above all the carbon atoms are surrounded by fluorine atoms. Again, the strong carbon-fluorine bond leads to the high chemical resistance of this material.
