Poly a fast running, general purpose, Class 155 polyurethane wire enamel. Suitable for monolithic or dual coat applications, it meets the requirements of NEMA MW 75, MW 80 (MW 79 on finer gauges) also meets the requiremets of JIS C 3003 for 'Pinhole' resistance. Poly is available in clear and colored versions. The primary benefit of the polyurethane is its easy solderability vs. the 180C tri2Sod solderable Polyester coating ( 2 seconds at 380°C vs. 5 seconds at 455°C) Polyeurethane can be readily used on Copper, Aluminum and CopperClad Aluminum wires as a basecoat for the commonly applied thermoplastic bondcoats. It is a costeffective insulation to be applied to wires that are used in the manufacture of precision coils, as it provides end users manufacturing benefits in handling and solderability. Typical applications are within motors, R.F. coils, relay, encapsulated coils, ignition coils, solenoids, low voltage transformers, Multi layer and precision wound coils, speaker voice coils.Information provided by Sandvik |
