FIELD: manufacturing technology.
SUBSTANCE: invention can be used in production of conductive materials, such as wires, cables, electroconductive agents of batteries or capacitors, antistatic or electroconductive agent for electroconductive paper, as well as belts, hoses, shoes, shafts, heaters, balloons or paints. Granular acetylene black has mass strength, measured in accordance with ASTM D 1937-10, not more than 200 N, average granule size, measured according to ASTM D 1511-10, at least 1.0 mm, average compression strength less than 65 kPa, iodine adsorption, measured in accordance with ASTM D 1510-11, from 50 to 150 mg/g, and absorbing capacity of OAN, measured in accordance with ASTM D 2414-09A from 140 to 320 ml/100 g. Said black is dispersed in resins, polymers or rubber.
EFFECT: high resistance to abrasion, stability during transportation, reduced energy during dispersion.
