Characters:milk white powder (particles). Density of 1.26-1.32. Soluble in benzene, chloroform, carbon disulfide, alcohol, methanol, ethanol, insoluble in gasoline, water, dilute acid, dilute alkali.
Uses:TBBS apply to NR, SBR, BR and its mix of fast curing, high modulus of vulcanized rubber. In the tire or rubber product formulations alone or with a small amount of speed enhancers, can effectively replace MBTS, DPG system. When the amount of low level at 10% CBS or NOBS available with the same modulus.
Packing:25kg plastic woven bag, Paper bag, kraft paper bag, woven bag or container.
Storage:Store in cool dry and should be single, a well-ventilated place. Packaged products should avoid direct sunlight, overlapping stacking will cause compression or granular products do not normally break. High humidity or high temperatures will cause product decomposition. Valid for 1 year.
Note:This product can make ultra-fine powder according to customer requirements.
