Acrylic stone, also commonly known by brand names like Corian (by DuPont), Staron, or Hi-Macs, is a type of solid surface material used in the manufacturing of furniture and architectural features. It is primarily composed of a mixture of alumina trihydrate (ATH), derived from bauxite ore, and acrylic polymer, which is a type of plastic.

Here are several key aspects of acrylic stone as a furniture material:

Composition and Manufacture

• Acrylic stone is approximately 33% acrylic resin (PMMA - Polymethyl methacrylate) and 66% natural minerals. The ATH works as a fire retardant and gives the material a particular robustness.
• It is manufactured in sheets that can be cut, shaped, and formed into a wide range of products.
• Pigments and dyes can be added to the mix to produce a vast range of colors, patterns, and effects that can mimic natural stone or present entirely unique designs.

Properties

• Non-Porous: One of the main advantages of acrylic stone is that it's non-porous, meaning that it does not allow liquids or gases to pass through. This makes it impervious to stains, and it does not harbor bacteria or mold, which is particularly important for surfaces in kitchens and bathrooms.
• Repairability: The material can be easily repaired if scratched or damaged, often by sanding and buffing the surface.
