In order justice the most diverse requirements

Ceramics are excellent materials
for electrical engineering because
they fulfil all requirements. Thanks to
their high mechanical strength, low
losses and good heat resistance,
these materials have very high
chemical stability and are preferred
because their very low wear. permissible temperature 250 130 160
Lower max. Furthermore, our
insulating materials contain neither pigments based on
heavy metals nor any substances that lead the formation
of dioxin furan.
The disadvantage comparison with thermoplastics the reduced
flexibility thermosetting plastics. higher thermal loads the deformation resistance of
thermosetting plastics better than that thermoplastics.

.
Ceramics are resistant heat,
fluids and sparks, and are tested
for leakage currents.
The continuous operating temperatures are higher than those of
thermoplastics.
Thermosetting plastics exhibit high dimensional stability, low water
absorption, extremely good tracking resistance and excellent fire
resistance.
