Continuous Cast Acrylic from Piedmont Plastics
Continuous cast acrylic sheet is a high-quality, cost-effective alternative to traditional cell cast sheet. Manufactured by pouring polymerized acrylic onto steel platforms, the material is continuously heated and cooled between highly polished steel plates. This precise process controls curing, resulting in an exceptionally clear, durable, and dimensionally stable product. One of the key advantages of continuous cast acrylic over traditional cell cast sheet is its ability to maintain consistent thickness and uniformity across the entire sheet, making it a reliable choice for a wide variety of applications.
Known for its versatility, continuous cast acrylic sheet comes in a broad selection of sizes, colors, tints, and textures. It offers terrific ease of fabrication and forming, allowing manufacturers to create custom shapes, displays, and installations with confidence. Its high molecular weight and superior thickness tolerance make it ideal for skylights, hot tub and spa enclosures, point-of-purchase displays, event displays, and signage. From commercial projects to decorative designs, this acrylic plastic sheet delivers outstanding optical clarity and long-term performance.
