Thermoplastic cast acrylic information
Acrylic, also known as Polymethyl Methacrylate or PMMA, is a transparent thermoplastic frequently used as a lighter and stronger alternative to glass. Acrylic was first developed in 1928 and brought to market in 1933. The material has since been sold under many names, including the R-Cast brand from cast acrylic sheet manufacturers Reynolds Polymer Technology, Inc. (RPT) and RPT Asia, Ltd.Acrylic is an alternative to glass particularly when safety is a factor. The structural strength of acrylic is impressive – it’s four times stronger than concrete, 17 times stronger than glass, and weighs half as much as glass. Additionally, the formability and exceptional optical qualities of cast acrylic make it a desired material in large aquariums, medical and scientific fields, architectural fields, and many others. Acrylic boasts a 92% light transmission rate and is enhanced with a UV-stabilizer to prevent yellowing in outdoor applications even in extreme conditions. This weatherability makes acrylic attractive as it will, with proper maintenance, still function properly and look like new even after decades in the field. Acrylic is considered non-toxic and is safe for food preparation.RPT Asia, Ltd. has the ability to cast acrylic up to 125 mm thick in a single pour. We also have the capability to laminate multiple thinner sheets together to reach final thickness up to 350mm.RPT Asia, Ltd. also offers the ability to bond, or chemically adhere, custom cast acrylic panels together to achieve the desired look with an invisible seam. The proprietary acrylic bonding method that RPT perfected maintains the strength of the acrylic and allows for greater design freedom when it comes to demanding seamless panels with panoramic views or seamless unique shapes, such as underwater dome rooms and aquarium tunnels.
