Bare Core Wire Specifications: POLY-NYLON (Class 155) (MW-80C) The litz core wire consists of nylon enamel film over a polyurethane enamel base coat. The nylon improves cut through temperature, windability, resistence to abrasion, and resistance to chemicals and solvents without a change to the soldering properties. Because of these properties, this insulation is preferred on 30awg and larger when a solderable film is required.
