ACETYLENE BLACK SEMICONDUCTING SHIELD MATERIAL WITH IMPROVED PROCESSING

摘要

A semiconducting shield composition comprising a polyolefin and acetylene black having at least one of the following properties: (a) a DBP oil adsorption of 150 ml/100 g to 200 ml/100 g; (b) an iodine absorption of 85 mg/g to 105 mg/g; (c) an apparent density of 0.2 g/ml to 0.4 g/ml; (d) a crystallite size along (002) less than 30 A; and (e) a carbon-carbon bond length along (100) less than 2.42 A. The semiconducting shield may be incorporated into a semiconducting layer and/or a semiconductor apparatus.
