Product Details

ies. It combines the advantages of PTFE (Polytetrafluoroethylene) and FEP (Fluorinated Ethylene Propylene) films, offering outstanding physical and chemical properties.

1. Thermal Stability

PFA film exhibits exceptional thermal stability, maintaining its performance over a broad temperature range.

  • Melting Point: 302°C
  • Continuous Use Temperature: -200°C to 260°C
  • Short-term Heat Resistance: Up to 310°C

This remarkable thermal stability makes PFA film ideal for high-temperature environments such as semiconductor manufacturing and high-temperature chemical processing.

2. Chemical Inertness

PFA film is highly resistant to almost all chemicals, including strong acids, bases, and solvents.

  • Chemical Resistance: Resistant to nearly all chemicals
  • Permeability: Low permeability, making it very effective in gas and liquid barrier applications

This property makes PFA film unparalleled in applications requiring chemical corrosion resistance.

3. Electrical Properties

PFA film also demonstrates excellent electrical insulation properties, making it an ideal material for electronic and electrical applications.

  • Dielectric Constant: 2.1 (@1 MHz)
  • Dielectric Strength: >200 kV/mm
  • Volume Resistivity: >10^18 Ω·cm

These parameters indicate that PFA film can provide reliable electrical insulation in high-frequency and high-voltage environments.

4. Mechanical Properties

PFA film has good mechanical strength and flexibility, maintaining its physical integrity under demanding conditions.

  • Tensile Strength: 30 MPa
  • Elongation: 300%
  • Hardness (Shore D): 55

This makes PFA film highly adaptable in applications involving mechanical loads and dynamic conditions.

5. Weather Resistance

PFA film is also highly stable against UV radiation and environmental conditions, making it suitable for outdoor and harsh environment applications.

  • UV Resistance: Excellent
  • Aging Resistance: Does not degrade with prolonged exposure to sunlight and climate changes

This property ensures the longevity and reliability of PFA film in outdoor applications.
