PCTFE Fluoropolymer Film

PCTFE 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:

Heat Resistance

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

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

  ·  Heat sealable

Chemical Resistance:

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

 · PCTFE films cannot withstand molten alkali metals, fluorine gas, and halogen compounds at certain pressures and temperatures.

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

Flame Resistance

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

Weatherability

  ·  PCTFE 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 insulatingmaterials.
