Special Grade Insoluble Sulfur

TYPICAL PHYSICO CHEMICAL DETAILS OF SPECIAL GRADE DIAMOND SULF

  • DS 90 is uncoated Insoluble Sulfur grade, which is available to specific requirements of users.
  • DS OT 25 AS is an oil coated Insoluble Sulfur grade having specific blend of precipitated silica of compatible fineness. The resultant product has good thermal stability and exhibits better dispersibility. Presence of precipitated silica improves flow characteristics of insoluble sulfur as it inhibits caking effect of oil and also helps in bonding of rubber compound to coated steel cord used for radial tyre and belting
  • DS OT 20(HD) is a special grade of DIAMOND SULF exhibiting higher levels of dispersion. during the mixing process this grade disperses more easily leading to reduction in incorporation time under identical conditions. This grade contains requisite quantity of suitable polymeric binder which facilitates better dispersion resulting in homogeneous vulcanization and physical properties
