PFA Fluoropolymer FILM

PFA film is a transparent, thermoplastic film that can be heat sealed, thermoformed, vacuum formed, heat bonded, welded, metalized, laminated (combined with dozens of other materials), and used as an excellent hot-melt adhesive. This wide variety of fabrication possibilities combines with the following important properties to offer a unique balance of capabilities not available in any other plastic film.

Product Feature:

    ·  Continuous service temperature : -240 to 260℃（-400 to 500℉）

    ·   Melting range:300to 310℃（572to 590℉）

    ·   Heat sealable

Chemical Resistance:

   ·  PFA film is stable to almost all chemicals and solvents. It also has low permeability to liquids, gases, moisture, and organic vapors.

   ·  It also has low permeability to liquids, gases, moisture, and organic vapors.

Flame Resistance

    ·  PFA films is flame retardant material with limited oxygen index (LOI) > 95%.

Weather Resistance:

    ·  PFA film can withstand long-term outdoor exposure without changing its performance.

    · High transmittance of ultraviolet and all, but far, infrared.

Mechanical Toughness

    ·  Superior anti-stick and low frictional properties.

    ·  High resistance to impact and tearing.

Electrical properties

     ·  High dielectric strength, over 250 kV/mm for0.025-mm film

     ·  No electric tracking, non-wettable, and non-charring

  ·  Very low dielectric constant, dissipation factor, and stable temperature change among solid insulating materials.
