Welcome to Shijiazhuang Baisheng Chemical Co., Ltd
95% Nano Zinc Oxide (20-100nm)
It's a kind of fine white or yellowish powder, with average particle size of about 30 nanometers, size range of 10 ~ 40 nm, compared with zinc oxide with direct and indirect method, it has a tiny grains, big specific surface area, and is easy to disperse, Our nanometer zinc oxide is refined from the ammonia - ammonium gel precipitation, mainly used to replace the zinc oxide by direct and indirect method, and used for a variety of natural rubber and synthetic rubber vulcanizing agent and reinforcing agent, white colored glue stains and filling agent, it can reduce the dosage of 30 ~ 50%,can also be widely used in all kinds of foam products, paint additives, feed additives, ceramic glaze, galvanized material, metal surface treatment phosphating liquid additives, cosmetics, catalysts, enamel, medicine, electronic sensors, antistatic material, etc.
