Manufacturing Hero Mobile

A story of progress.

In 1946, we began our journey with boron chemistry as a catalyst to make life better. Over the course of 70 years, we’ve become one of the world’s leading providers of specialty chemicals for a variety of industries. Our commitment to quality inspired us to build world-class production plants in Elma, Washington, and Evans City, Pennsylvania, allowing us to meet our strict standards at a large scale. Every day we develop solutions to improve the way our clients create their products, making what they do easier, safer and more efficient.
