Insulating Silicone

This range encompasses those grades that are suitable for applications requiring electrical insulation.

The insulating materials resist combustion arc tracking and environmental degradation. As such, they are ideally suited for use with high voltage and power transmission equipment such as insulators, surge arresters, and casing pipe.
