Corian is a solid, nonporous, homogeneous surfacing material, composed of ≈1/3 acrylic resin (also known as polymethyl methacrylate or PMMA), and ≈2/3 natural minerals. These minerals are composed of aluminum trihydrate (ATH) derived from bauxite, an ore from which aluminum is extracted. Corian is an advanced composite product used as an architectural and design material in a variety of residential and commercial applications. Corian solid surface offers design versatility, functionality and durability. Supplied in sheets and shapes, it can be fabricated with conventional woodworking tools into virtually any design. It is the original solid surface material made only by DuPont. Flowing, virtually seamless, organic shapes, bold effects of color and translucency—if it can be imagined, it can be created with Corian . Corian is available in a vast range of trendsetting patterns and tones, as well as your own custom-designed colors. In baths and kitchens and beyond, throughout homes and hospitals, restaurants, and public spaces, Corian solid surfaces deliver high performance and outstanding aesthetics. Corian continues to evolve and to inspire unprecedented creative flights of design fancy, combined with functionality.
