Ningbo Great Southeast Wan-Xiang Science & Technology  Co.,Ltd

Products: 

Two main kinds of BOPP polypropylene capacitor film:

□ The plain Bopp capacitor  film (MP) with corona treatment  in one side for metallzing.

Feature:the metallized films produced by this product have mechanic,physical,and uniform mctallized layer with high attachment force and anti-oxidation.

Application:used for low power shunt capacitors,AC motor running capacitors,and the various DC-high frequency capacitors.

Thickness:3.8µm-15µm

□ Rough surface BOPP capacitor film (RP,RRP) with one side or both sides rough surface for impregnation.

Feature:they are produced by high purity and high ISO-tactical portion PP resin raw material.Two step flat stretching in both orientation,and have low dissipation factor,high diclectric strength,good compatibility with various impregnation diclectric oils and sovent-less.

Application:used for film-paper component capacitors or full film capacitors. Include high power capacitors .electrical-heating oven capacitor . microwave oven capacitors etc.

Thickness: 6µm-15µm
