No.6（2003）14.Development of electric material using waste plastic

Katsumi YAMAMOTO, Yasuo TONOYA and Hiroshi SHIGEMATSU

We developed plastic compound, taking advantage of high insulation of waste plastic. We used PET as matrix and ABS or FRP as fill. We prepared test pieces of the compound and measured their volume resistivity, dielectric constant, dielectric loss tangent, and dielectric breakdown voltage under a constant temperature and humidity. We examined the compounding uniformity of the fill by observing vertical sections of the pieces with as electron microscope. The PET-ABS compound is easy to form. The PET-FRP compound is more difficult to form, as increasing FRP. The compound has adequate electric characteristics for insulation and is suitable for insulating barrier material, etc.
