Corian is a solid surface material composed of acrylic polymer and alumina trihydrate made by DuPont. It is said to be a thermosetting plastic, but can be thermoformed by heating it to 300°F, allowing unique shapes to be created. Its primary use is for countertops. Corian is available in thicknesses of one-quarter, one-half and three-quarters of an inch, with half-inch being the most common thickness for most applications. All thicknesses feature the consistency of color and patterning throughout common to all brands of solid surfacing material . This allows scratches, stains and light scorches to be removed with sandpaper. Joints can be made invisible by joining them with a special seam adhesive and sanding the connection smooth. The disadvantages of Corian are that it scratches easily, can be damaged by chemicals and is not heat resistant, so it can be melted by hot pots and pans. Corian is far more expensive than laminate and butcher block countertops and significantly more expensive than tile, but is less expensive than high quality granite.
