As the core dielectric material of film capacitors, capacitor base film boasts excellent dielectric properties, temperature resistance stability, and mechanical strength.

It is widely used in new energy vehicles, photovoltaic inverters, wind power converters, industrial frequency converters, consumer electronics, and other fields, providing efficient energy storage, filtering, and voltage stabilization support for various power electronic equipment.

It is a key foundational material ensuring low-loss and long-life operation of equipment.

It is made of high-purity electrical grade uniform polypropylene resin, which is biaxially stretched by the flat film method. It has the characteristics of good thickness uniformity and easy rolling. It can be applied to the field of capacitors with roughened films or used in thin film capacitors after high vacuum metallization.
