The ultraviolet irradiated polypropylene (PP) with the oxygen polar groups on its chain was blended with the inorganic filler STC (Sericite-Tridymite-Cristobalite).
The interelectrode dielectric adopts the polypropylene film with surface coarsening which is easy to impregnate so as to enhance the reliability of high-capacity capacitor.
It was suggested that polypropylene resin was packed with rankinite fiber treated with silanizing coupler andmica in a suitable propotion,could obtain optimum composite properties.
The silver lining is a combination of a thin layer of aluminum and a plastic called oriented polypropylene, which is the same stuff Grocery bags are made of.
