Upgrade product so it can withstand harsher and more demanding operating conditions.
Evaluate and select a high-temperature resin whose electrical properties exceed those of the engineering grade resin currently being used and can withstand the harsher environment.
For this application High-Temperature Plastics were evaluated due to their superior properties. Some of those properties are as follows:
For this application electrical resistance was the key criteria. Consequently a polyetherimide was chosen that had a dielectric strength of 710 volts/mil. This compared well against the engineering resin (polycarbonate) previously being used that had a dielectric strength of 380 volts/mil.
