The most important usage for zinc oxide is as an activator in rubber industry. However the inorganic Zinc Oxide is not so easily to disperse in organic rubber polymer. How to increase the dispersion on rubber is the most important thing for Zinc Oxide manufactory. The Wet Process Zinc Oxide is one way we consider. In this process, we can make more fine particle size zinc oxide to increase the surface area. The higher surface area of zinc oxide, the easier to disperse in rubber. Here is the comparison of?Active Zinc Oxide?with French Process Zinc Oxide .
?
| ? | Active Zinc Oxide | French Process Zinc Oxide |
True specific gravity | 4.8 | 5.47 |
Apparent density | 0.54 | 0.6 |
Surface Area(m2/g) | 30-50 | 3-5 |
Lead (Pb)% | 0.0010 | ~0.05 |
pH | 8.5-10.0 | 7.0 |

As compared with French type zinc oxide, Active zinc oxide is :?
1.??Specific gravity is smaller.
2.??The surface area is much higher, so the crossing linking density is higher.
3.??Harmful impurities are less.
4.??It contains very low lead and create no blacken, the color of vulcanized rubber is much clear.
5.??Due to its micro particle size, it is superior in dispersion shortening of vulcanization cycle ??resulting in saving of machine time and power consumption.
?
ADVANTAGE FOR ACTIVE ZINC OXIDE :?
1. ? Active ZnO improves the degree of cross-linking and thus improve the modulus,
????? tear resistance and abrasion resistance. It also improves aging properties and gives
????? good protection?against flex cracking.
2. ? With their extremely fine particles, Active ZnO easily disperses thereby facilitating the
????? process of latex compounds, thus behaving as a good activator e.g. in teats, gloves,
????? balloons and?similar articles, it reduces pin holes in latex products and also provide
????? shine??/ transparency on finished products.
?
3.????It has a much lower content of heavy metals.
?
4.?????It is very suitable for transparent or translucent rubber products and those with a?low zinc oxide content.
?
5.? ? ?A large dosage of the product can serve as the anti-softening agent, preventing?rubber materials from ? ? ? ? ? ? being transformed easily. It also can be used as the filler for?light-colored rubber.
?
6.? ? ?The tear resistance, tensile coefficient, and wear resistance of rubber products are?all higher.
?
7.? ? ??Its content of heavy metals meets the strict standards of fodder additives, and the?quality is excellent ? ? ? ? ? ? (refer to the attached table).
?
8.????Strict quality control allows the zinc oxide content of the finished product to reach?the upper limit in that ? ? ?activity level (higher than the products of the same level?available on the market), leading to the best ? ? ? ? ? ?condition of vulcanization, and?offering the user the highest economic efficiency and quality.
