About us


Established in 1972, this company began as a specialized trading company dealing with unique clay minerals. Within that role, we have been focusing on utilizing untapped resources and developing new applications for them. Since then we have continued to maintain that perspective as we began to work with different products in a variety of areas. A further key to our success has been our approach to continuous improvement and our capacity for product development.
Going forward we will continue in this way to bring forth products that meet the needs of the market while maintaining close relationships with clients and suppliers alike.
