Product Description View more Close tab

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.

NOTE: BOTH ends of wire are accessible. Actual amount of wire may fluctuate from 79 to 81 lbs.
