ECTFE Fluoropolymer Film
ECTFE film is made of ECTEF resin as raw material through melt extrusion. Its surface is smooth and the product has excellent performance in all aspects. Because of its outstanding tear resistance and water vapor barrier properties, it is very suitable for use in photovoltaic front panel coating and constrictions field.
Product Feature:
Heat Resistance
· Continuous service temperature : -200 to 150℃(-328to 300℉)
· Melting range:240℃(464℉)
· Heat sealable
Chemical Resistance:
· ECTFE 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
· ECTFE films is flame retardant material with limited oxygen index (LOI) >52%.
· Film auto-ignition temperature>650℃
Weatherability
· ECTFE 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, Hydrophobic, oleophobic.
· High resistance to impact and tearing.
Electrical properties
· High dielectric strength, over 30 kV/mm for1mm film.
· No electric tracking, non-wettable, and non-charring
· Very low dielectric constant, dissipation factor, and stable temperature change among solid insulating materials.
