Polycarbonate and Acrylic: Clear Plastics with Clear Differences
Tuffak® Polycarbonate and Optix® Acrylic (PMMA) are two very similar looking plastics. Both are often bought as transparent sheets with similar smooth glossy surfaces, and are often used as tougher and more impact resistant alternatives for glass in industrial and consumer applications. These two materials can be found in windows, viewing panels, protective barriers, eye-wear, display cabinets, and similar applications. However, polycarbonate and acrylic actually have very different physical properties and resulting applications.
Polycarbonate: Industrial Grade Impact Resistance
Tuffak® Polycarbonate (manufactured by Plaskolite) is an amorphous thermoplastic material, meaning it has a low degree of crystallinity and a more random polymer chemical structure. This gives the plastic an interesting combination of physical and optical properties, such as transparency comparable to silicate glass and an exceptionally high impact and chemical resistance.
Its exceptional impact resistance has made this particular material popular for manufacturing in sheet form, a lot like sheet metal. It can be rolled, pressed, heated, and formed without cracking or breaking. Polycarbonate can be fabricated quickly and relatively inexpensively into shapes not possible with glass thanks to its chemical structure.
Polycarbonate is commonly used in protective applications, such as barriers and bullet-proof windows, ceiling panels, displays, and enclosures. Despite its impact resistance, polycarbonate tends to scratch easily, so it is not well-suited to displays and applications that require high aesthetics.
OPTIX® Acrylic (PMMA): Durability on Display
Acrylic, short for poly-methyl-methacrylate, (PMMA) can come in many forms, including a sheet material typically referred to as acrylic glass. Like polycarbonate, acrylic is an amorphous thermoplastic, though it features much better transparency. Tough and strong, yet acrylic impact resistance is not as high as that of polycarbonate.
Optix® Acrylic (manufactured by Plaskolite) offers a higher tensile strength and UV resistance than polycarbonate, as well as much better optical characteristics. Acrylic is also easy to clean and maintain, and is generally pretty easy to fabricate, so long as it’s masked for protection during handling. This, combined with being less expensive has made acrylic common in display and consumer applications.
There are many different applications for acrylic thanks to these properties, ranging from LEDs to displays to even consumer windows. Optix® Acrylic sheet can be found in shop displays and enclosures, ceiling skylights, media discs, and fiber optics, as the material is a lightweight and tougher alternative to glass.
