Abstract

PURPOSE: To obtain a composition having good IEC tracking and excellent mechanical properties, by adding to a polyalkylene terephthalate a hollow microspherical substance selected from alumina, silica, zirconia and magnesia.
CONSTITUTION: A polyester composition is prepared by adding to (A) 100pts.wt. of a polyalkylene terephthalate, (B) 3W200pts.wt. of at least one hollow microspherical substance having an average particle diameter of below 2mm, selected from the group consisting of alumina, silica, zirconia and magnesia. As the component (A), polybutylene terephthalate having a high rate of crystallization is preferably used. Preferably, the component (A) has a relative viscosity ranging 1.3W1.8, when measured at 25°C, as a 0.5% solution in o-chlorophenol.
