Product Description

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 film for type
M-PP/S-PP

■ Features
By adopting the imported super high-purity capacitor-grade home-polypropylene resin, the film is made by biaxial-orientation tenter process.The film features excellent profile evenness, high BDV and high mechanical strength. The winded capacitors take on the characteristics of low dielectric dissipation and high insulation resistance.

■ Application scope：
M-PP：Mainly for metallized-film capacitor.
S-PP：Mainly for foil-film capacitor.

■ Film thickness code：

The nominal film thickness is indicated by its central value (integer value, e.g. 5,6.7 the first f
igure after decimal or its codes. The nominal film thickness of this company is the Mechani-
cal Method Value (MMV) under 10 layers testing.
