Zinc oxide is an essential additive in the rubber and tire industry; it is also used as a vulcanization activator and reinforcement agent, as well as a coloring agent for natural rubber, synthetic rubber, and latex. It can also be used in the chemical industry for coatings, enamels, pigments, and more. It possesses excellent activation properties, and its use in rubber products is becoming increasingly widespread. For example, in V-belts, it can replace conventional zinc oxide in equal amounts while reducing the amount required by 1/2 to 1/3; this helps maintain the various functional parameters of the rubber, without affecting its vulcanization properties, thereby reducing production costs. It replaces zinc oxide used in rubber products. It has the following characteristics: 1. The particles of active zinc oxide are small and spherical in shape, offering high activity and a large surface area. This gives it excellent dispersibility and adsorption capabilities, which enables it to promote the vulcanization, activation, and reinforcement of rubber as well as to enhance its resistance to aging. It also accelerates the vulcanization process and improves the tear resistance and wear resistance of rubber products. 2. Low specific gravity and low content of harmful substances (such as Pb, Hg, Ge, Mn, etc.) ； 3. Activated zinc oxide mixes easily with the rubber compound and disperses uniformly, which can increase the viscosity of the compound; therefore, a smaller amount of activated zinc oxide is required compared to ordinary zinc oxide ； 4. It can improve the stability and thermal conductivity of the extruded product’s shape. 5. Also functions as an NBR anti-aging agent. 6. Improved oil resistance. 7. Significantly reduces the cost of rubber compounds, leading to higher productivity and better efficiency. 8. Can be used as an antideformation agent to prevent rubber mixtures from deforming; it can also serve as a filler in light-colored rubbers. 9. Has a lower ratio of heavy metals compared to zinc oxide produced by the French method. It contains extremely low levels of heavy metals, so it does not affect the quality of the products and does not cause pigment stains; its impact on the whiteness of rubber products is minimal. 10. It is highly suitable for rubber products that are transparent or semi-transparent, as well as those with very low zinc content. 11. The ultra-fine particles disperse easily within the rubber, allowing for the use of less zinc oxide compared to conventional methods. 12. When used in large quantities, it acts as an antideformant, helping to prevent rubber compounds from deforming; it can also be used as a filler in light-colored rubbers. 13. It improves the tear resistance, tensile strength, and wear resistance of rubber products. 14. It widens the range of possible vulcanization conditions, thereby significantly reducing the risks of under-vulcanization or over-vulcanization. 15. Its heavy metal content meets the strict standards required for feed additives, ensuring high quality. 16. Active zinc oxide features smaller particle sizes compared to conventional zinc oxide, lower levels of impurities, and a larger relative surface area.
