Rating: Enamel Type: Enamel Build: Average Wire Diameter: Manufacturer: Product Line: Color: Solder Process: Approvals: Applications: Product Description 42 AWG Solid Round Copper C (in accordance with ASTM D 2037 test procedure) Polyvinyl Acetal-phenolic Heavy build Essex USA Formvar Gold Remove enamel before soldering. NEMA Designation (MW 15-C/A) IEC Designation ( , ) Oil-filled transformers, motors, solenoids, good thermal shock resistance. 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. It continues to be the recommended film insulation most commonly used in oil-filled transformers. Formvar easily passes 175 C heat shock.

NEMA Designation (MW 80-C) IEC Designation ( ) UL Recognized Appliance motors, relays, timer and clock coils, encapsulated coils. Soderon combines the magnet wire insulation characteristics of polyurethane with the advantages of a polyamide (nylon) topcoat. With the nylon, Soderon is still readily solderable, yet the solvent resistance and thermal stability of the insulation is excellent. In addition, the nylon improves windability and tolerates more severe winding operations. Soderon is an excellent choice for automatic winding machines.

NEMA Designation (MW 35-C/A), IEC Designation ( , , ) UL Recognized 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. GP/MR-200 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, it is superior in regards to physical moisture, chemical, and thermal resistance. GP/MR-200 is an extremely moisture-resistant film insulation coating, suitable for many uses including: open motor, high moisture applications, and hermetic applications. Other outstanding properties include thermal life, thermoplastic flow, burnout, and head 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.
