Characteristics and functions:
1、the activity is strong, granularity and the dispersion is strong, has the good to promote the role of sulfide, improved the crosslinking density of the vulcanizates, sulfurized more thoroughly.
2、 can better improve the rubber viscosity, raise skeleton material such as rubber and steel wire and cord adhesion.
3、 dynamic mechanics performance is good, small deformation of the rubber products, less heat production, good wear resistance, good aging resistance.
Packaging and shipping:
1、the plastic outside double packing
2、the standard package: 25 kg
3、pay attention to moisture during transportation and storage
