Another Plastic High Voltage Insulator

A PET thermoplastic polyester resin known as Rynite is being used in racing car ignitions. In that application , it must withstand high temperature, high vibration as well as being able to withstand the 50kV ignition voltage.

One grade of Rynite, FR946, is one such example. At 150°C, the dielectric strength grade is close to 90% of the room temperature rating.
