            Applications

            Zinc oxide finds a wide applications in fine chemicals, rubber, coatings, electronic components, pharmaceuticals, glass, ceramics, viscose, photosensitive electronics, paint, paper, plastics, magnetic materials, refined petroleum, natural gas desulfurization, high energy batteries, building materials,etc.

             

            99.7% Zinc oxide is filtered by 100 mesh during processing to ensure the quality required for higher dispersion, no dust, easy to weigh. As an activator, 99.7% zinc oxide is generally used with stearic acid in sulfur vulcanization process to improve vulcanization efficiency.

             

            Packing: Net 25KG/ bag

            Recommended dosage: 2.5-6.5phr

            Storage: Stored in a cool, dry place, away from direct sunlight.
