Composition :80% of Zinc dibutyldithiocarbamate
20% of Carrier and dispersant
Appearance :White or yellow particles
Density :About 1.09 g / cm 3
Function :Rubber Acelerator BZ can cause rapid vulcanization of natural rubber and synthetic rubber,such as SBR,NBR,EPDM.Besides the addition of thiuram and dithiazole accelerators can slow down the rate of vulcanization and improve the safety of the operation. Rubber Acelerator BZ has a shorter scorch time and a slower full cure rate comparing with ZDEC-80,ZDPC-80 and ZDMC-80. JXBHgran ZDBC-80 has an activating effect on conventional accelerators.
Dosage :NR: 0.6-1.0 phr ; Second accelerator, 0.1-0.2 phr SBR / NBR:0.6-1.2 phr ; Second accelerator, 0.1-0.2 phr
Application :Rubber Acelerator BZ can be used for tires, conveyor belts, V belts, round tape, fire hose, other reinforced hoses, soft containers, fabric gluing.
Package :25 kg in carton box with polyethylene bag liner
Storage :Cool and dry conditions, the storage period of one year.

super accelerator which used in natural rubber, synthetic rubber and latex. The activity in rubber is greater than ZDEC. Preserved milk containing Rubber Acelerator BZ can be used for one week without any early vulcanization and is a good activator for thiazole accelerators. This product has the role of antioxidant in the mixing, can improve the aging resistance of vulcanized rubber, do not change color, do not pollute, easy to disperse.
