FLUOROPOLYMERS
PTFE (Polytetrafluoroethylene)
- Outstanding Coefficient of Friction, Chemical Resistance, High & Low
Temperature Capability, Non-Stick and Electrical.
- PTFE is processed by Compression, Isostatic or Automatic Molding. It is
also processed by Extrusion.
- Fillers, such as glass fibers, carbon powder, carbon fibers, molybdenum
disulfide & bronze powder, are added to Decrease Creep and Wear.
- Modified PTFE used for Increased Creep Resistance, Reduced
Permeation & Better Weldability (vs. standard PTFE).
- The working temperature of PTFE ranges from -450 F to +550 F.
PFA (Perfluoroalkoxy)
- The chemical and physical properties of PFA are similar to PTFE.
- However, unlike PTFE, PFA is melt processable by injection molding.
- The maximum use temperature of PFA is 550 F.
ETFE (Ethylene-Tetrafluoro-Ethylene)
- ETFE is a strong, impact resistant polymer with good radiation
resistance. It has good resistance to most chemicals, but is attacked by strong oxidizing agents and chloronated solvents. ETFE can be processed by injection or compression molding.
- The maximum use temperature of ETFE is 400 F.
PVDF (Polyvinylidene Fluoride)
- PVDF offers good strength, wear resistance and creep resistance. It
also has good resistance to chemicals and a maximum use temperature of 300 F. PVDF is processed by injection molding.
