IS - 80 , Yellow Powder , Used In Tire , Buffers , Hose And Belts.
Recommendations and Applications:
Insoluble sulfur is mainly used as a senior accelerator and curing agent in rubber industry.
Compared with the common sulfur, it has the following advantages.
No blooming of rubberduring the storage period.
No migration between the adjacent rubber.
Anti-scorching in the process of mixing and storage. Shorten the curing time.
Increase bonding between rubber and material.
It is widely used to produce tires and other rubber composite products, such as the tire, buffers,
white tire sidewall, hose, belts.
It can also be used in cables, roller, oil seal, soles and other rubber products, as well as in light color
rubber products when sulfur is used in large amount.
Compare with S-80 , IS-80 imparts good blooming resistance and physical properties of the
compound and products , with hight viscosity and better processability of the masterbatch.
