Yellow powder with little odor,no poison. The relative density is 1.70-1.82. It is not stability, and at vulcanization temperatures OT20 will de-polymerize to soluble sulfur Insoluble in CS, and water.

Packing:
25kg/ bag

Performance and Application:
1.Improved flowability. The improved product flowability provides easy handing, a less dusty enviroment and less tendency for product to compact.
2. Improved dispersibility. The special additive package in OT20 helps to reduce the tendency for electrostatic charge build-up and hence the formation of agglomerates which can be formed during mixing as a result of the small particle size of insoluble sulfur. 

Applicable Rubbers: 
Natural rubber, CR, SBR, NBR and EPR etc
