| 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
