Enameled wire insulation materials include PU, polyester, PEI, PAI, PI and special overcoat systems selected by solderability, thermal class and winding requirements.
Insulation Materials Comparison for Magnet Wire
Compare magnet wire insulation materials including PU, polyester, PEI, PAI, PI, nylon overcoat, self bonding layers and corona-resistant systems.
Enameled Wire Insulation Types
Enameled wire insulation types include polyurethane, polyester, polyester-imide, polyamide-imide, polyimide and overcoat systems selected by temperature, solderability and application.

Polyester-Imide Enamel Insulation
Polyester-imide enamel insulation is used for higher temperature magnet wire in motors, transformers and generators where heat resistance and winding reliability matter.
