    HAPT 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. HAPT 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 Applications

    • Fractional and integral horsepower motors (hermetic and open)
    • Automotive and power tool motors
    • General purpose motors
    • Dry-type transformers
    • Large coil applications - unvarnished, varnished or encapsulated
    • Electronic Coils

  • Heavy Poly Nylon Round Magnet Wire

    HPN combines the magnet wire insulation characteristics of Heavy Poly with the advantages of a nylon topcoat. With the nylon, HPN is still readily solderable, yet the solvent resistance and thermal stability of the insulation is excellent. In addition, the nylon provides improvement in the windability and tolerates more severe winding operations. HPN is an excellent choice for automatic winding machines.

    Typical Applications

    HPN has excellent solderability and the 130/155°C thermal class. It has wide use in coils and small motors. It is not recommended where severe overloads are experienced.

    • Appliance motors
    • Relays
    • Timer and clock coils
    • Encapsulated coils
    • Guitar Pickups

  • Heavy Poly Nylon Round Magnet Wire

    HML is a film-coated magnet wire made with aromatic polyimide resin. It is a Class 240 insulation with exceptional resistance to chemical solvents and burn-out. It will operate at temperatures in excess of 240°C for intermittent duty. The outstanding thermoplastic flow of over 400°C and its ability to withstand excessive overloads extends the use of magnet wire in extreme conditions. HML is unaffected by prolonged exposure to varnish solvents and is compatible with most systems.

    Typical Applications

    Whenever high temperatures and extreme overload or ambient conditions are required, HML magnet wire may be used.

    • Fractional and integral horsepower motors
    • High temperature continuous duty coils and relays
    • Hermetic and sealed units
    • Heavy duty hand tool motors
    • Encapsulated coils

    Formvar is a synthetic enamel composed of polyvinyl acetal and phenolic resins.

    Formvar's hot oil resistance sets it apart from all other magnet wire insulations. The flexibility, adhesion and abrasion scrape resistance of Formvar film is excellent. Its electrical properties are very good and it is resistant to common solvents. While Formvar has been replaced in many applications, Formvar continues to be the recommended film insulation most commonly used in oil-filled transformers.

    Typical Applications

    • Oil-filled transformers
    • Motors
    • Random wound coils
    • Solenoids
    • Guitar Pickups




    For Use in Guitar Pickups

    Formvar serves as an excellent choice of winding wire for pickup manufacturing companies and is chosen for it's resistance to common solvents (including sweat and other liquids that can find its way into a guitar's pickup). Heavy Formvar is used where top end brightness and note definition are desired, due to fewer windings than with thinner wire with more windings.

    Guitar Pickup Winding Wire for Warmth and Note Definition...

    Formvar serves as an excellent choice of winding wire for pickup manufacturing companies and it is chosen for it's resistance to common solvents (including sweat and other liquids that can find its way into a guitar's pickup cavity). Heavy Formvar is used where top end brightness and note definition and clarity are desired attributes, since fewer turns are possible due to the thickness of the insulation. A certain famous guitar maker used Heavy Formvar in their single coil pickup windings throughout the early 1950's and 1960's. This is the best choice for period-correct, authentic single coil pickup winding wire.

    General Properties of Plain Enamel

    Plain Enamel magnet wire is insulated with a synthetic resin enamel. It is the oldest of the film insulations and all basic properties are good. Relatively easy removal of film by mechanical or chemical means. Good moisture resistance.

    Excellent Windability...

Heavy Poly Nylon's heavy coating is an excellent choice for vintage-voiced pickup wire.

    Vintage Tone...

    Plain Enamel is a magnet wire insulation type used in vintage pickup windings and today is used in vintage reissue guitar pickups. Plain Enamel is often defined visually by it's dark purple / brown-ish tint. Don't be fooled by companies that tint and dye other insulation types as a substitution for the real deal; supply is limited for plain enamel since it is mostly used in smaller quantities by pickup winding companies in vintage-spec'd guitar pickups.
