We are a 200 plus year old leading global provider of silicates, silicas & derivative products that enable environmental improvements, enhance consumer products, and increase personal safety. With our value-added products, we seek to address global issues that are often either the subject of significant regulations or are driven by consumer preferences, which we believe fuels our growth. Since our products are predominantly inorganic and carbon-free, we believe we contribute to improving the sustainability of our planet.
