For simple electrical insulating applications where a thin film is required polyester films are probably the most common type of electrical insulator material used.

Ceramic is a well known electrical insulator for many general applications yet the ceramic materials may lose the insulation under very high temperature above 600 c in recent years to use the ceramic thin film as an electrical insulation for the sensor becomes one of the bottleneck on intelligent engine applications.
With this in mind a primer in common and not so common electrical insulating materials may be helpful.
Electrical insulation is the absence of electrical conduction.
Intelligent turbine engine requires new sensor.
Test sensors were fabricated on the insulating films on stainless steel substrates and survived welding lead wires to the sensors without shorting to the substrate.
Insulation on the wire coils consists of up to four thin layers of polymer varnish film.
