| Fluon®PFA is
a copolymer of tetrafluoroethylene (C2F4) and
perfluoroalkoxyethylene, which has excellent chemical, electrical,
mechanical and surface properties. PFA retains many inherrent characteristics
and similar properties of PTFE but can be processed using conventional
thermoplastic techniques, such as extrusion molding, injection molding,
blow molding, or electrostatic powder coating. And Fluon®PFA
can be used in a wide range of temperatures from extremely low to
high temperatures (260°C at the maximum) without losing its superior
properties. |
| The features
of Fluon®PFA |
| Fluon®PFA combines many
excellent features peculiar to perfuluoro-resin, as follows. |
| Outstanding chemical resistance |
| Chemically stable material not attacked
by most chemicals. So Fluon®PFA is the most suitable material
for semiconductor equipment parts, which are in constant contact with
strong chemicals. Asahi Glass is lining up "Ultra Pure Fluon®PFA",
a special grade for the semiconductor field, in which extracted metals
are reduced to extremely low levels. |

Outstanding
chemical resistance |
|
| Chemically
stable material not attacked by most chemicals |
|
|
High
mechanical strength |
|
| Retains
high mechanical strength and can be used in a wide operating
temperature range of temperatures from -200°C to +280°C. |
|
|
Good
electrical properties |
|
| Outstanding
insulating material having a very low dielectric constant and
a very low dielectric dissipation factor, which contributes
to higher reliability in the electronics field. |
|
|
Noncombustibility |
|
| Oxygen
index at 95% or more; noncombustability resin to be used in
various fields. |

|
Low
surface energy |
|
| Low
friction, non stick, and high water and oil repellency surface
characteristics; improve resin reliability produces good effects,
such as reducing resistance of fluids |
|
|
Outstanding
weatherability |
|
| No
reduction or deterioration by direct sunlight, wind, rain, and
exhaust gas; characteristics do not change when exposed to the
outdoors for a long time. |
