Corian is the brand name for a solid surface material created by E. I. du Pont de Nemours and Company ( DuPont). Its primary use is as a countertop/benchtop surface, though it has many other applications. It is composed of acrylic polymer and alumina trihydrate (ATH), a material derived from bauxite ore. Corian is the original material of this type, created by DuPont scientists in 1967. A number of direct solid surface competitors to Corian have emerged since the expiration of DuPont’s patent on solid surfaces.
Corian is manufactured in three thicknesses: , , and . Most Corian is manufactured at a DuPont facility near Buffalo, New York. Cross-section cuts show consistent color and particulate patterning evenly distributed throughout the material, giving rise to the category name “Solid Surface.”
Corian must be sold and installed by a DuPont certified fabricator and such installations come with a 10-year warranty covering both product and installation, for interior residential applications.
