Fluoropolymers Comparison

MATERIAL		DESCRIPTION
PTFE Poly-tetra-fluoro-ethylene		PTFE is also sold under the brand names Teflon and Dyneon
PFA Perfluoroalkoxy-copolymer		Similar to properties to FEP Higher melting point Improved mechanical properties at higher service temperature compared to FEP PFA is also sold under the brand names Teflon and Dyneon
FEP Fluorinated Ethylene-Propylene		Mechanical properties similar to PTFE Same electrical and chemical properties as PTFE Has higher tensile and impact strength than PTFE Harder and has better clarity vs PTFE Slightly lower coefficient of friction than PTFE Lower service temperature compared to PTFE
PCTFE Poly-chloro-trifluoro-ethylene		Higher tensile strength and improved clarity vs PTFE Has a lower softening point than PTFE Less chemical resistance compared to PTFE Lower electrical insulation vs PTFE PCTFE is also sold under the brand name Neoflon
ECTFE CTFE/Ethylene copolymer		Low creep and impact strength Behaves more like nylon than any of the fluoropolymers ECTFE is also sold under the brand name Halar
ETFE TFE/Ethylene copolymer		Similar properties to FEP Enhanced abrasion and impact properties vs FEP Lower service temperature than FEP ETFE is also sold under the brand name Tefzel
PVDF Poly-vinylidene copolymer		Good properties at a relatively low price Good tensile and impact strength Generally good chemical resistance Sacrificed dielectric properties PVDF is also sold under the brand name Kynar
PVF Poly-vinyl-fluoride		Similar properties to PVC with better heat stability PVF is also sold under the brand name Teflon
