Polyamide-imide Enamel

Magnet wire insulating film based on an aromatic polyamide-imide resin. It is based on trimellitic anhydride (TMA). The film is tough, smooth and abrasion-resistant. It has high dielectric strength that is maintained under humid conditions and after long-time aging. It resists deformation under heat and pressure. It can be used in applications as high as 220°C (428° F). This enamel has found its greatest use as an overcoating for other enamels.
