Common plastic insulating materials include Polyvinyl Chloride (PVC),
Polyethylene (PE), Polypropylene (PP), Polyurethane (PU), and Polytetrafluoroethylene (PTFE).
Each of these materials has unique characteristics that make them suitable for various electrical and electronic applications.
PVC is widely used for cable sheathing due to its excellent flame retardancy and flexibility;
PE boasts good electrical insulation properties and chemical resistance,
making it ideal for the insulation layer of low-voltage wires;
PP features a higher melting point and mechanical strength, fitting for situations requiring high temperature stability;
PU stands out for its exceptional wear resistance and elasticity, suitable as protective coatings or outer jackets for flexible cables.
Notably, PTFE not only provides superior electrical insulation but also exhibits outstanding heat, cold, and corrosion resistance,
maintaining stable performance even in extreme conditions.
