GP/MR-200 round heavy build magnet wire is the standard of comparison for magnet wire performance in virtually every severe and heavy duty application. The combination of a modified polyester basecoat and an improved polyamideimide topcoat results in an insulation system with outstanding physical toughness, excellent dielectric properties, and superior chemical resistance to most common solvents and refrigerants. -

Windability of GP/MR-200 round heavy build magnet wire, verified by years of experience on virtually every type of winder, has always been excellent. Improvements in the topcoat have resulted in a product that is even more superior with regard to high slot fill and insertability. GP/MR-200 magnet wire insulation exhibits high dielectric strength retention under high moisture conditions.
