0.055mm super thin enameled copper wire for hearing aids
For polyester and modified polyester enameled wires, the thermal
grade of ordinary polyester enameled wire is 130, and the thermal
grade of modified enameled wire is 155. The product has high
mechanical strength, and has good elasticity, adhesion, electrical
properties and solvent resistance. Its weaknesses are poor thermal
shock resistance and low moisture resistance. It is currently the
largest variety in my country, accounting for about two-thirds, and
is widely used in various motors, electrical appliances,
instruments, telecommunication equipment and home appliances.
