A Fluoropolymer for the next Age
Fluon®ETFE is a thermoplastic fluoropolymer developed by Asahi Glass. It is a copolymer comprising of tetrafluoroethylene (C2F4) and ethylene (C2H4). Fluon®ETFE is a balanced fluoropolymer that has chemical resistance and electrical properties comparable to typical fluoropolymer, such as PTFE, PFA and FEP and also is more progressive than ECTFE or PVdF with its improved mechanical strength and very easy mldability.
We are convinced that Fluon®ETFE offers customers the best solution, such as cost reduction compared to the use of other fluoropolymers, or shifting from conventional materials.

|
|
| With the characteristics of fluoropolymers, extrusion
molding, injection molding and powder coating are available, as with
general thermoplastic resins. Filming, heat-sealing, composition with
rubber and various secondary processes are possible. |
| Good Performance Over a Wide Range of Temperatures |
| Stable mechanical electrical properties are maintained
over a wide range of temperatures, -200 - +180°C. Continuous service
at 180°C is possible. |
| Excellent Chemical Resistance |
| Almost all chemicals, from hard acids and hard bases
down, will not affect the properties of Fluon®ETFE. |
| Exceptionally Good Electrical Properties |
| Fluon®ETFE is an excellent insulator and
has a high break-down voltage with thin film. A low dielectric constant
dielectric tangent would be evident over a wide range of frequencies. |
| Nonflammable, Non-poisonous |
| Flammability: UL-94V-0. Tasteless, odorless, non-poisonous
and suitable for almost any purpose. |
| Good weatherability beyond 10 years |
| Screens ultraviolet-rays (UV) and does not deteriorated
as a result of contact with UV. |
| Excellent Low Surface Energy |
| Good surface properties, e.g. low friction constant,
anti-adhesion and water/oil repellency give the lowest of flow resistance. |
