Through a diverse team of talented and experienced people, we develop, manufacture, and bring to market solutions that are largely renewably sourced and help customers solve complex problems while making the world more sustainable. Our products are used in a variety of demanding applications, including adhesives, agrochemicals, asphalt paving, bioplastics, coatings, elastomers, lubricants, paint for road markings, oil drilling, and automotive components. We operate in three reportable segments: Performance Materials, Performance Chemicals and Advanced Polymer Technologies. Our Performance Materials segment manufactures products in the form of powder, granular, extruded pellets, extruded honeycombs, and activated carbon sheets. Performance Materials engineers, manufactures, and sells hardwood-based, chemically activated carbon products which are produced through a highly technical and specialized process primarily for use in gasoline vapor emission control systems in internal combustion engines and hybrid electric vehicles including cars, trucks, motorcycles, and boats. To maximize the productivity of our manufacturing assets, we also produce several other activated carbon products for food, water, beverage, and chemical purification applications. Our Performance Chemicals segment consists of our road technologies and industrial specialties product lines. Performance Chemicals products serve as critical inputs used in a variety of high-performance applications, including pavement construction, pavement preservation, pavement reconstruction and recycling, and paint for road markings (road technologies product line), as well as agrochemical dispersants, lubricants, certain adhesives, rubber, and other diverse industrial uses (industrial specialties product line). Our Advanced Polymer Technologies segment produces caprolactone and caprolactone-based specialty polymers for use in coatings, resins, elastomers, adhesives, bioplastics, and medical devices.
