Heavy armored polythermaleze round magnet wire on spool showing copper winding

Single Armored Polythermaleze Round Magnet Wire

Magnet Wire

SAPT is a multi-purpose film insulation which has a modified polyester basecoat and a polyamideimide topcoat. This combination provides a film insulation which has physical toughness, excellent dielectric properties, and superior chemical resistance to common solvents and refrigerants. Thermal properties of over 200°C qualify it for severe thermal overload applications. Compared to nylon overcoated polyester, the properties most improved are physical moisture, chemical and thermal resistance. SAPT is an extremely moisture resistant film insulation coating, suitable for many uses including open motor, high moisture application and hermetic applications. Other outstanding properties include thermal life, thermoplastic flow, burnout and heat shock.This product is the standard of excellence for motor repair, maximum result, and minimum reject applications. It is impressive because it couples the extra advantages of high moisture resistance with ease of insertion.Typical ApplicationsFractional and integral horsepower motors (hermetic and open)Automotive and power tool motorsGeneral purpose motorsDry-type transformersLarge coil applications - unvarnished, varnished or encapsulatedElectronic Coils
