Design, characteristics, possibilities to customise, comparisons with other materials. A selection of the most questions about Corian® and our answers.

Is Corian® made from plastic?

No. Corian® is composed for one third of transparent acrylic resin (poly(methyl methacrylate) PMMA) and two thirds natural minerals. The principal among these latter is alumina trihydrate (ATH), a white powder derived from bauxite, the mineral from which aluminium is extracted. It is a mineral material in powder form held together by an acrylic resin.

Does Corian® suffer from ‘yellowing’?

No. Corian® is colour stable and non-photosensitive. This is because it contains an acrylic binding agent that does not turn yellow. However, some materials that imitate Corian® do turn yellow if exposed to light owing to their different composition.

Is Corian® toxic?

No. It is a non-toxic material that creates no problems with dust or harmful emissions. Even when it is worked, vacuum systems attached to equipment minimise concentrations of dust.

Is it possible to paint Corian®?

Yes, using acrylic paints from NCS and RAL colour palettes.
Owing to the processes involved in their fabrication, wash basins and bathtubs can only be painted externally; for the same reason, only the panels of vanity cabinets and not the top are painted.

Can Corian® be polished?

Corian® is produced with an opaque finish and provided with this finish to fabricators belonging to the Corian® Quality Network. After cutting and shaping it to create a workable surface, they supply it for installation with the same finish. Continue reading Can Corian® be polished?

What is the minimum radius for thermoforming Corian®?

It is possible to thermoform Corian® in Glacier White, creating a fold with a minimum radius of 50 mm, using a mould and a counter mould. While dark colours of Corian® can be thermoformed, this creates a light area along the fold line whose appearance needs to be considered in relation to the desired result. Textured surfaces, such as coarse grain dots, instead, are damaged during the heating phase; before undertaking a project that involves thermoforming, we suggest getting in touch with us to discuss the details.

What is the difference between Corian® and quartz?

Quartz is a mineral material in coloured granules held together by acrylic or polyester resins. It is rigid, heavy, impossible to repair or restore. Joints are always visible.
Corian®, instead, is a compact material, held together by acrylic resins. It is simultaneously flexible and rigid, allows for invisible joints and can be repaired if damaged. The number of possible joints is almost infinite.

Coloured Corian®: is it available also in dark colours?

Yes. The Corian® colour palette also contains dark colours, though not all are recommended for countertops or surfaces subject to intense wear because they are sensitive to dragging and tend to scratch easily. Solid dark colours or marble- or stone-effect textures are instead useful as surfaces and cladding.

Where can I buy Corian®?

Corian® can be purchased from kitchen retailers or cabinet makers, if the order includes the kitchen, or directly from a fabricator when all you need to do is substitute the countertop. For the bathroom, retailers of bathroom fixtures are the ideal reference for purchasing a washbasin, shower tray or bathtub. Reception desks and cladding for bar counters can be purchased directly from a Corian® fabricator or from the cabinet maker providing the rest of the furnishings.

Who installs a shower tray or bathtub in Corian®?

This is generally done by the plumbing contractor installing the other elements in a bathroom. Planit offers plumbing contractors and installers a free technical information service.

Can I install a shower tray in Corian® directly on top of ceramic tiles?

Yes, so long as the installation surface is perfectly level. If this is not the case, it must be levelled using an appropriate product.

How can I tell if a product in Corian® is authentic?

Corian® panels are branded on the underside and edge with a serial number and DuPont™ logo. After the material has been worked, it can be difficult to find these markings, though every original product is accompanied by documentation demonstrating its authenticity.
