Zinc Oxide Production

About US


Since 1969 we have been producing Zinc Oxide of best quality.
Our standard assortment contains four varieties of Zinc Oxide, but as a family-owned company, we can offer a highly personalised service tailored to meet your individual requirements.
Our product stands out of competitive brands because of its higher level of flowability. This ease of flow prevents blockage of in-plant transportation pipes.
It is our utmost concern that the production is most environmentally sustainable, and we are always aiming at 100% security of supply, including reliability and the adherence of delivery dates.
In order to maintain the striking quality of our Zinc Oxide we are ISO 9001-certified, and our being a full member of the International Zinc Organisation allows International Orientation to be one of our core competences.
