Formvar is a single enamel system copper magnet wire designed for continuous operation at 105 degrees and is used in oil-filled transformers, coils, motors, as well as demanding cryogenic applications. It is one of the first magnet wire insulations based on the synthetic material polyvinyl acetal and phenolic resins.
CW Formvar is available in a single enamel system on copper conductors.
