The inherent low loss and small dielectric constant of PTFE materials make it possible to manufacture enameled wires for control equipment, thermocouples, micro motors, etc.; it is an ideal material for manufacturing transformers, motors, insulated cables, radio insulating gaskets, and capacitors. Using the selective air permeability of the fluoroplastic film with high oxygen permeability and low water vapor permeability, oxygen sensors can be manufactured; using the characteristics of fluoroplastics to deviate from the polar charge under high temperature and high pressure, it can be used to manufacture speakers, microphones, robots and other components ; With its low refractive index characteristics, optical fibers can be manufactured.
