POLYCARBONATE COMPOSITION HAVING IMPROVED ELECTRICAL TRACKING RESISTANCE

摘要

The electrical tracking resistance or a high molecular weight aromatic polycarbonate composition containing silica flour or Farsil type respectively quartz flour of Farsil type is improved in comparison with glass fiber reinforced high molecular weight, aromatic polycarbonate compositions whereas the good mechanical and thermal properties of the glass fiber reinforced aromatic polycarbonate compositions are almost achieved. The polycarbonate composition of the invention optionally contains a hydrophobic inert pigment. The polycarbonate composition of the invention may be used for making components which are associated with electrical conductors.
