Technical Feature
The predispersed masterbatch IS 90-65 contains 90% sulfur which is composed of 65% insoluble sulfur (insoluble in CS2) and 40% soluble sulfur. It serves as the vulcanizing agent for all natural rubbers and diene rubbers. Compared with common sulfur, the outstanding features of the pre-dispersed IS are no blooming and no shifting to other layers. Therefore, it is widely used in the manufacture of tires, conveyor belts, rubber shoes, and other rubber products that require no blooming, multi-layer vulcanization, and high adhesive property.
Processing Advantage
Generally, powdery insoluble sulfur is easy to fly and adhere to devices. It is difficult to disperse evenly during mixing. However, the predispersed IS solves these problems. It will not agglomerate under normal storage conditions. It has good flowability. There is no powder flying during mixing. Quick blending into various rubbers and uniform dispersion ensure optimal activity of the effective ingredient.
Application
Tires, conveyor belts, retreaded tires, rubber tubes, seals, rubber rollers, etc.
