Premium Cast Acrylic from Piedmont Plastics

Piedmont Plastics is a wholesale distributor of high-quality cast acrylic products, including acrylic sheet, rod, and tube. Also known as plexiglass, cast acrylic is versatile, reliable, and perfect for many applications. It's made by pouring liquid acrylic into molds that can be set into various shapes and sizes, such as flat sheets or cylindrical rods and tubes. This process results in a product that is clearer, stronger, and more resistant to impact and weather than alternative materials like glass.

One of the biggest advantages of cast acrylic is its superb clarity and light transmission. It's also about half the weight of glass and much safer due to its shatter-resistance. Our customers appreciate that our cast acrylic products are easy to work with. They can be cut, drilled, and shaped to fit any unique requirement, making them ideal for everything from architectural features to retail displays.

Common uses of cast acrylic include items like signage, displays, fixtures, framing, and do-it-yourself projects. In addition, cast acrylic is often made into parts and components for industrial, marine, automotive, or manufacturing applications where precise dimensions and durability are crucial.

Frequently Asked Questions

Have questions about acrylic? Our FAQs cover the essentials to help you make informed decisions.

Polycarbonate and acrylic are both clear plastics. Polycarbonate is extremely impact resistant, more flexible, and handles higher temperatures. However, it scratches more easily and is usually more expensive. Acrylic offers better optical clarity, is more scratch resistant, easier to cut and polish, and holds up better to UV exposure. Acrylic is also more affordable, but less durable under impact.

Yes, acrylic can be easily cut and fabricated to meet a wide range of design and application needs. It can be cut using lasers, saws, or routers and is also well-suited for processes like bending, drilling, polishing, and bonding. Piedmont Plastics also offers cut-to-size services to meet your needs.

Yes, standard acrylic is more prone to scratching than materials like glass. However, scratches can often be polished out, and scratch-resistant (hard-coated) acrylic options are available for applications that require more durability.

To clean acrylic, use a soft, non-abrasive cloth or sponge with mild soap and water. Avoid using ammonia-based cleaners (like glass cleaner) or rough materials, as they can cause scratching or clouding. For tougher spots, specialized acrylic cleaners and polishes are available for purchase to help maintain clarity and shine.

Yes, Plexiglas® is a brand name for acrylic, much like how Kleenex® is a brand of tissues. Acrylic is the generic term for this transparent plastic material, and it’s sold under several brand names.
