摘要

PROBLEM TO BE SOLVED: To provide a granular deposition preventive agent for unvulcanized rubber exhibiting excellent deposition preventability, further having satisfactory dispersibility into water even at room temperature, free from the scattering of dust and also having satisfactory handling ability.SOLUTION: Provided is a deposition preventive agent for unvulcanized rubber. The deposition preventive agent being granular, also, in the deposition preventive agent, the mass of the grains in which grain sizes lie in the range of 0.10 mm mesh-on to 2.0 mm mesh-pass is 60% or more and the mass of the grains in which grain sizes of 2.0 mm mesh-on or more is below 30%.
