The
above-mentioned values are typical values at 23°C, unless otherwise
stated. They are intended as a guideline for material determination.
They cannot be used for drawing up material specifications. They do
not discharge the user of effecting his own tests in order to
determine whether a material is suitable for the application.
- Test
speed: 50 mm/min.
- Test
speed: 5 mm/min.
-
Temperature resistance over a period of several months to several
years. The given temperature limits are determined by the
thermal-oxidative degradation which takes place and causes a
fall-off in properties (embrittlement). Besides, as for all
thermoplastics, the maximum service temperature depends essentially
on the duration and the magnitude of the mechanical stress to which
the material is subjected.
-
Measured on a 2 mm thick test specimen. As with other materials, the
dielectric strength diminishes with increasing sheet thickness, e.g.
for 3 mm sheet the dielectric strength is 16 kV/mm, for 6 mm sheet
11 kV/mm.

These ratings are not intended to reflect hazards presented by the
material under actual fire
