ETFE Film

Fluon®ETFE Film

Fluon®ETFE Film is a highly sophisticated film that is produced by AGC.
It does not contain plasticizers or adheisives. So the excellent properties of fluoro resin are maintained.
It is used in various industries including electronics, aerospace, solar and interior design because of high heat resistance, chemical resistance, non stick and excellent electrical properties.

ETFE resin which is a raw material used as the basis of Fluon®ETFE Film, is a crystalline thermoplastic with a melting point of approximately 265-270℃. For general use, however, it is practical to use Fluon®ETFE Film at continuous service temperature determined by the long-term change of tensile elongation, which accurately reflects thermal deterioration of the polymer.

Fluon®ETFE Film is stable against most chemicals and has excellent chemical resistance.

Fluon®ETFE Film has light very high transmittance exceeding 90% from UV rays to IR rays.
Fluon®ETFE Film can maintain its optical properties and its superior mechanical properties for a long time.
One of the examples proving this is the first greenhouse which has been covered with Fluon®ETFE Film since 1985 It has no problems to use and Fluon®ETFE Film shown practically no signs of aging.
Fluon®ETFE Film shows almost no aging after 1500 hours of accelerated weather resistance testing (Sunshine Weather-O-Meter). This test procedure is equivalent to 29 years in the sun.

光線透過特性

Fluon®ETFE Film has very good optical properties and has high sunshine transparency.
The light transmittance of Fluon®ETFE Film is over 95% and it is very suitable for use as greenhouse covering.

Fluon®ETFE Film has low surface energy which in turn offers non-stick characteristics, for example, soil will not stick to its surface.
In addition snow slides down the Fluon®ETFE Film by itself. Dust and sand is removed by wind, rain and snow.
The above characteristics mean that in effect Fluon®ETFE Film is ''self-cleaning''.

Electrical properties
Electrical properties

The top figure shows the frequency effect of the dielectric contact of some fluoropolymers.
In the frequency range of 60-1010 Hz, the dielectric constant of Fluon®ETFE Film is not as same as that of PTFE and FEP, but is far lower than that of PVdF.
Furthermore, at high frequency above 106Hz, ε tends to be lower.The second graph shows temperature vs. dielectric constant, ε remains constant over a wide range of temperatures.

The above to the left figure shows the effect of frequency on the dielectric tangent(tanδ) for Fluon®ETFE Film.
Tanδ in Fluon®ETFE Film has a maximum value close to 108Hz.
The figure to the right shows the temperature vs. the dielectric tangent. The plotted lines are different according to the frequency.
