Polyurethane enameled wire; heat grade is 130, 155, 180, 200. The biggest feature is that it has straight solderability, good high frequency performance, easy coloring and good moisture resistance. It is widely used in electronic appliances and precision instruments, telecommunications and meters. The weakness of this product is that the mechanical strength is slightly poor and the heat resistance is not high. And the production of large-size lines has poor flexibility and adhesion, so the specifications for the production of this product are small and medium-sized.
Polyester imide/polyamide composite enameled wire, heat grade 180 This product has good thermal shock resistance, high softening breakdown temperature, excellent mechanical strength, good solvent resistance and refrigerant resistance, and the weakness is easy under closed conditions. Hydrolysis, widely used in motors, electrical appliances, instruments, power tools, electric dry-type pressure cookers and other windings.

Polyesterimide/polyamideimide composite layer enamelled wire is currently used in a wide range of heat-resistant enameled wire at home and abroad, its thermal grade is 200, the product has high heat resistance, and also has anti-freezing agent, cold resistance and radiation resistance. Other characteristics, high mechanical strength, stable electrical performance, good chemical resistance and refrigerant resistance, and strong overload capacity. Widely used in refrigerator compressors, air conditioning compressors, power tools, explosion-proof motors and motors, electrical appliances used in high temperature, high cold, radiation resistant, overload conditions.
