SEMICONDUCTIVE COMPOSITIONS AND CABLE SHIELDS EMPLOYING SAME

摘要

Novel semiconducting compositions for use in semiconductive cable shields having improved electrical properties as measured by ACLT and AWTT are described. The composition comprises a base polymer and about 25 percent to about 45 percent by weight of carbon black having particle size of from 15 nm to 22 nm, Iodine number of from 120 mg/g to 150 mg/g, and DBP number of from 90 cm3/100 g to 170 cm3/100 g.
