Our factory imported four capacitor polypropylene film(BOPP) lines and lab instruments from German Bruckner Company and French DMT company in 1989 , 1997 ,2002and 2005 respectively. The yearly output is 12000 tons . We produce 4μm--12μm plain films for metallization purpose and 6--18μm mono-side or dual-sides rough films (They can also be treated with corona discharge.)

     For so many years our factory has concentrated on the specialized research, development and manufacture of Capacitor PP Film. In virtue of the edges of metallized film and capacitor production, Tong Feng has been edging ahead with researches and practices, developing innovative process solutions uninterruptedly, enhancing product quality, engaging some overseas renowned specialists to be our tech-consultants and enabling company's filmquality to invariably maintain at domestic leading position and to enjoy considerable high reputation in this industry at home and abroad.

  Capacitor Polypropylene film(the biggest manufacturer in the world)：

M-PP/S-PP：Mainly for metallized-film capacitor（4μm--12μm ）For example, (5μm)FOB:$7694 /T .
RPP/RRPP：Mainly for foil-film capacitor（6μm --18μm）

Capacitor Polypropylene Rough film type RPP/RRPP 　　　　

　　■ Features
By adopting the imported super high-purity capacitor-grade homo-polypropylene resin, the rough film is produced by biaxial-orientation tenter process. The film features excellent physical and electrical properties, such as good profile evenness， high electric strength， low dielectric dissipation and good windability etc. The film can company with a good many kinds of capacitor impregnation oil well. According to the authentication from National Power Capacitor Test Center, the product conforms to all the requirements of capacitor insulation materials.


　　■ Application range:
　Mainly for power, electrothermal and other relevant kinds of high voltage capacitors designed as foil-film or foil-film & paper with oil-impregnation.
