MWS stocks Formvar insulated magnet wire in most sizes to AWG 51. Across the industry the use of solderable films such as Class 155 polyurethane-nylon have supplanted Class 105 Formvar. Formvar remains superior to poly-nylon in properties such as abrasion and chemical resistance, and stability at very low temperatures. Thus, it continues to be used in oil filled transformers and certain cryogenic applications.
