Abstract
Pelleted sulfur compositions consisting essentially of particles of sulfur which include a substantial proportion of carbon-disulfide-insoluble sulfur particles together with a binder consisting essentially of a plasticizing or softening oil containing an anionic or nonionic surfactant in an amount equivalent to between 0.5 and 10% of the weight of the pelleted composition, the pelleted composition containing an amount of the plasticizing oil equivalent to between 10 and 60% of its weight. The pelleted composition is free-flowing, storable, and disperses homogeneously when distributed in rubber mixtures by milling on heated compounding rolls.

A pelleted sulfur composition consisting essentially of particles of sulfur which include a substantial proportion of carbon-disulfide-insoluble sulfur particles together with a binder consisting essentially of a rubber plasticizing oil containing an amount equivalent to between 0.5 and 10% of the weight of the pelleted composition of an anionic or nonionic surfactant, the amount of the plasticizing oil being equivalent to between 10 and 60% by weight of the pelleted composition.
