Use: The purpose of developing this product is to replace thiuram accelerators such as TMTD, mainly because thiuram accelerators are easy to produce carcinogenic nitrosamines, and diphenylnitrosamines are not carcinogenic. Used in NR, SBR, EPDM, NBR, NBR systems can be used as a rapid primary or secondary accelerator, which is safer than TMTD and has a longer anti-focus time, and is sometimes used as PVC rubber vulcanization inhibitors.
Packing: 25kg plastic woven bags, paper-plastic composite bags, kraft paper bags.
Storage: Should be stored in a cool, dry, well-ventilated place. The packaged products should be protected from direct sunlight, and the stacking between the trays should not be overlapped, and the overlapping stacking or temperature exceeding 35 C will cause abnormal compression of the product. Valid for 1 year.
