FEP (fluorinated ethylene propylene)
PTFE and FEP are similar in their material properties. The main difference between PTFE and FEP lies in the maximum operating temperature and the colour. PTFE is milky/white and FEP is clear transparent.
• Lower melting temperature than PTFE
• More flexible than PTFE
• Low dielectric constant (insulating)
• Chemically inert
• Very low co-efficient of friction
• Antistick properties
• UV resistant (does not age)
• Not hygroscopic (water absorption <0.01%)
• FDA approved
• Working temperature from -200°C to +205°C
FEP is typically used in applications where clarity is required (soil analysis/sight glasses, etc.).
Additional information about the properties of FEP can be found under the technical data sheets.
