ViviOn™(CBC)-Polypropylene Blends for High Heat Resistance Film Capacitor Applications
2023/03/17 11:35:00
ViviOn? (CBC) MDP-0011 key properties - High purity polymer
- High temperature performance (Tg~147℃)
- Low dielectric constant and dielectric loss
Due to the technical development of wide band-gap (WBG) semiconductor materials, traditional biaxially oriented polypropylene (BOPP) film capacitors can no longer meet the heat resistance requirements of their applications. By adding specific amount of ViviOn? to PP for a blend or extruding ViviOn?(CBC) as a single layer in a multi-layer film with PP, ViviOn? can effectively improve the dimension stability of BOPP film under high temperatures.
