Specific gravity is smaller.
The surface area is much higher, so the crossing linking density is higher.
Harmful impurities are less.
It contains very low lead and create no blacken, the color of vulcanized rubber is much clear.
Oxide De Zinc Actif 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.
With their extremely fine particles, Oxide De Zinc Actif 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.
Use of Oxide De Zinc Actif results in good dimensional stability to extruded profiles, tubing and open air cured articles in general, the effect particularly pronounced in EPDM compounds.
Generally, active Zinc oxide use about 20-40% lesser than French Process ZnO gives desired results. With fine tuning of formulation settings, considerable savings can accrue on account of lower inputs such as: machine time, power consumption, accelerators and blowing agents etc..., in many formulations, THUS GIVING ECONOMY AND BETTER PROCESS CONTROLS IN ULTIMATE ANALYSIS.
