Summary for polyesterimide magnet wire Discussion
Mixing of polyester and polyesterimide in magnet wire production is described by the questioner, who says their plant near New Delhi is coating 9.15 x 3.21 mm copper strip with polyester in the first 8 passes and polyesterimide in the last 4 passes. They report first- and second-zone temperatures of 280 °C and 340 °C, plus catalyst-machine temperatures of 460 °C before catalyst and 450 °C after catalyst. The excerpt provided does not include a substantive technical reply, so no conclusion about whether the process is correct or how to adjust it can be drawn from the text shown. The only named person in the source is Ted Mooney, P.E., RET, but no answer content from him appears in the excerpt.
