Polypropylene Film

Polypropylene film is a transparent flat film with very uniform thickness. It shows good mechanical and excellent dielectric properties. Suitable for solid dielectric materials of paper-film structural power capacitor and other insulation materials for electrical purposes.

Widely used in capacitors, cable wrapping, and various electrical insulation applications.
