Boron minerals which are widely found in Turkey and U.S.A. has become quite popular during recent years due to their superior flame reatardance capabilities in electric systems. In this study four different types of boron minareals such as tincal, ulexite, colemanite and boric acid has been used. In the first part of the study polyester samples blended with different type and concentration of boron minerals has been tested in laboratory conditions according to ASTM D 2303 surface tracking test method. At the next stage before the test rocess similar sampleshave been aged artificially by using DC vibration motor according to results the mean breakdown time increase with boron concentration. However lateral vibration has reduced the service life of composite samples up to 50 %
