Application:Developed to replace thiurams such as WILLING TMTD where the presence of nitrosamines is of concern The dibenzylnitrosamine is not carcinogenic according to published literature. A fast curing primary secondary accelerator in NR, SBR and NBR applications. Be safer to progress, providing longer scorch times than WILLING TMTD. Sometime used as retarder in the vulcanisation of PVC rubber.

Packaging:25kg plastic woven bag, paper with plastic film bag, kraft paper bag.

Storage:The product should be stored in the dry and cooling place with good ventilation, avoiding exposure of the packaged product to direct sunlight. The product with pallet should not be stacked. Stacking of palletized material or temperature of above 35οC can cause unusual compacted product. The validity is 1 year.

Properties

Tetrabenzyl thiuram disulfide is an environmental friendly rubber vulcanization accelerator with excellent performance, abbreviated as TBzTD. Although it still belongs to thiuram class, the dibenzylnitrosamine generated has a large molecular weight, is a non carcinogenic substance that is neither volatile nor soluble in water, and the amount of the product is small, and it is non-polar and will not spray frost, so it has a wide range of applications.
