At Cornerstone, we enable the U.S. military to fly faster.
We produce the acrylonitrile used in vehicles, aircraft and a host of other applications. Our high quality acrylonitrile is sought after as a key component in the carbon fibers that go into automotive and aerospace products. For example, Cornerstone supplies acrylonitrile to America’s largest producer of aerospace-grade carbon fibers and a leading supplier to the U.S. Department of Defense. Cornerstone’s acrylonitrile goes into the carbon fibers that make up the wings of the U.S. military’s F-35 fighter, helping ensure U.S. military dominance in flight for decades to come. Our acrylonitrile also goes into carbon fibers that help passenger airplanes such as the A350 use less fuel which reduces emissions and increases range, opening new longer haul flight routes.
