130 grade polyurethane coated polyamide film insulated round aluminum magnet wire is composed of polyurethane and polyamide, the polyurethane provides good heat resistance and mechanical properties, while the polyamide increases the wear resistance and chemical stability of the coating.
Characteristic:
| Adhesion and Flexibility | No visible cracks in the film coating |
| Elongation | Not less than 15 |
| Thermal Shock | No visible cracks in the film coating after conditioning at 175ºC |
| Dielectric Breakdown | 14-23.5 AWG: Single Layer or Type 1: ≥ 2470V-3520V Heavy Duty or Type 2: ≥ 4390V-6330V Triple Layer or Type 3: ≥ 6590V-8540V 24-37 AWG: Single Layer or Type 1: ≥ 680V-1350V Heavy Duty or Type 2: ≥ 1140V-2430V Triple Layer or Type 3: ≥ 1550V -3250V |
| Continuity | 14-24 AWG: Maximum number of discontinuities conforms to 750±5% – 1500±5% Maximum number of discontinuities conforms to 10-25. |
| Solderability | After soaking at the specified time and temperature, the insulation layer is completely removed as specified. |
Regular compliance testing:
| Solubility | Samples immersed in xylene should not soften enough to expose bare conductors |
| Dielectric breakdown at rated temperature | Average value not less than 75% of the required value at room temperature |
