ZINC OXIDE
We are supplying superior quality products backed by our wealth of accumulated expertise and
technologies.
We have been manufacturing zinc oxide since the company was founded. Zinc oxide is made from high purity electrolytic zinc, so it can be used in a wide range of applications from rubber and paints to plastics, electronic materials and cosmetics.
In addition, our products have a great reputation for performance, such as
ultrafine products used as UV shielding agents in sun care cosmetics and large particle products used as heat-dissipation fillers in electronic parts.
Sakai Chemical Group’s Strengths
- We offer a broad product lineup from nanosize particles to large particles.
- Our technology of surface treatments provides higher dispersivity and other special functions.
