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
