6. Use
The predispersed masterbatch BZ-75 is used as the accelerator for natural rubber, synthetic rubber, and latex. It has larger activity than ZEDC in dry rubbers and it is a good activator for thiazole accelerators. It does not change color or produce pollution, and it is easy to disperse. The latex containing this product can be used for a week without prevulcanization. In addition, the predispersed BZ-75 can improve the anti-aging properties of the vulcanized rubber.

7. Packaging
Woven bag lined with plastic bag or kraft paper bag, 25kg/bag
