Polyester glass fiber: Polyester glass fiber is a composite material, mainly composed of polyester resin and glass fiber. The conductor part of polyester glass fiber enameled rectangular copper wire is pure copper wire, usually with a circular cross-section. Polyester resin is known for its good flexibility and insulation, while glass fiber is known for its high strength and high temperature resistance. Combining the two, polyester glass fiber has both the flexibility and insulation of polyester and the high strength and high temperature resistance of glass fiber. This makes this material widely used in many fields.
