polyamide-imide enamel varnish
Polyamide-imide resin insulating paint includes polyamide-imide resin containing no halogen element in its molecular chain which is dissolved in a polar solvent, in which the polyamide-imide resin contains an aromatic diisocyanate component (A) having three or more benzene rings or an aromatic diamine component (E) having three or more benzene rings in a monomer, and a ratio M/N between a molecular weight (M) of the polyamide-imide resin per repeat unit and an average number (N) of amide groups and imide groups is equal to or more than 200.
Why do the enameled wire manufacturers use the polyamide-imide enamel varnish?
hybrid cars are becoming popular as the result of the energy conservation policies. To improve fuel economy in hybrid cars and motor performance, drive motors are controlled by inverters and rapidly becoming smaller, lighter, highly heat-resistant and are driven under higher voltage. To meet a request for higher motor performance, such as small size, light weight, and high heat resistance, windings currently used for the motor coil require polyamide-imide enameled wires which have excellent heat resistance, mechanical characteristics that can withstand severe coil formation, and mission oil resistance. The mission-oil resistance greatly effects insulation-retaining capacity depending on types and quantities of oil additives. However, if influences of an oil additive are excluded, hydrolyzability due to moisture absorption is directly related to mission-oil resistance.
Advantages of Polyamide-imide resin insulating paint
Polyamide-imide resin insulating paint is a heat-resistant polymeric resin having heat resistance properties, excellent mechanical characteristics, and hydrolyzability resistance properties in which amide groups and imide groups are compounded at a ratio of approximately fifty-fifty. polyamide-imide enamel varnish has low permittivity and high partial discharge inception voltage.
