 | Anhui Tongfeng Electronics (Group) Company | | Product Detail | Capacitor Polypropylene film for type | Description:
| Product Class : Electronic Material·Insulating Material
■ 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.
