Corian

From Wikipedia, the free encyclopedia

Corian is the registered trademark of one of many building materials collectively known as solid surface and is 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 (149°C), allowing unique shapes to be created. Its primary use is for kitchen worktops and bathroom vanity tops, but is also commonly used as a wall cladding in moisture applications (wet walls). Solid surface materials are very versatile and can be joined, shaped and finished to create many products.

Corian is manufactured in three different sizes 6mm, 12.7mm and 19mm. When fabricated into work surfaces a MDF subframe is used to create a thicker work surface, usually work surfaces are fabricated to 38mm in thickness this consists of the 12.7mm corian with a 25mm sub-frame. All thicknesses feature the consistency of color and patterning throughout, common to all solid surfacing materials. This allows scratches, stains and light scorches to be removed with sandpaper. However, doing this tends to scuff up its matte coating, and is not recommended for single scratches; the preferred method is to lightly sand the entire counter top so the coating is uniform. Joints can be made inconspicuous by joining them with an acrylic resin which settles into the joint and is then belt sanded and polished to create the seamless joint. With recent price reviews in Europe, Corian is probably the most cost effective solid surface when comparing like for like.[citation needed] Corian was first sold in 1967 [1].

[edit] Residential Applications

Today, Corian is considered a desirable material for use in kitchen countertops, and can be a helpful selling point in marketing a house. It is available in a variety of colors and patterns. It has found an unusual use in the manufacture of string nuts for guitars, where its hardness, ability to take precise cuts and whiteness are advantageous.

[edit] Direct competition

Meganite solid surface has 80 closely replicated color matches with similar chemical makeup as Corian. Additionally, it continues to introduce unique colors inspired by current design trends and natural hues. The material is available to certified fabricators in various sizes and thicknesses including the traditional 1/2", but also, 1/4", 2cm, and 3cm sheets. The product is popular with the design community because the company will custom match almost any color and have a sample available in two weeks.

The LG Group markets its 100% acrylic solid surface under the LG HI-MACS brand and it is manufactured in both Korea and in the US just outside Atlanta, Georgia. LG HI-MACS offers similar styles,quality and colors to DuPont. Acrylic solid surface can be renewed, in most cases, simply by the consumer's using a Scotch-Brite scouring pad. As far as heat is concerned, it is recommended that trivets be used, as opposed to placing hot pots and pans directly onto the surface.

Samsung's Staron solid surface is a competitor. Wilsonart has its Gibraltar solid surface. LivingStone Surfaces made by US Surface Warehouse (USSW) is another competitor with 30 colors/patterns and covered by a limited transferable warranty for 15 years.

A more expensive, different approach to the countertop industry is Avonite. Avonite is a solid surface, but made primarily from a polyester base, not an acrylic one. This allows for greater depth of colour, but is a more brittle product.

EOS Solid Surfaces produces a polyester/acrylic solid surface in various sizes, including 3cm and 2cm thickness. The material is intended to convey some of the architectural and product-design connotations of traditional stonework, whilst maintaining economic and physical properties which are distinct from actual stone. For example, the surface does not support the growth of mold; may be cheaper than stone in some applications; and can be easily formed and joined. These properties may be desirable, for example, in buildings in the hospitality and health-care sectors. EOS have applied for patents on this material.
