Zinc Oxide

My company of zinc oxide were 99%,99.5% and 99.7%,which is a white or light yellow powder micros trip. It can be easily dispersed in rubber and latex in natural rubber, synthetic rubber reinforcing agent, active agent and curing agent, it is also a white plastic materials coloring agent and filler, also can be used for enamels, chemical reagent, military, and fireworks.
