Melos A.S Activce Zinc Oxide is carefully produced by multi-step chemical processes starting with high quality zinc ingots and powders in our facility located in Sakarya 3. Industrial Zone. Zinc oxide particles in the rubber compund can only react with the chemicals in it with its surface. Therefore, the reaction ability of zinc oxide is determined by its surface area, not its mass. Melos A.S Active Zinc Oxide types can have a surface area up to 70 m2 / gr, so it reacts much faster and more effectively.
