Acrylic products include acrylic sheets, acrylic plastic pellets, acrylic light boxes, signboards, acrylic bathtubs, acrylic artificial marble, acrylic resin, acrylic (latex) paint, etc., with a wide variety of products. Commonly seen acrylic products are acrylic products assembled from raw materials such as acrylic pellets, plates, or resins through various processing methods, combined with various parts of different materials and functions. As for the commonly heard acrylic fiber, acrylic cotton, acrylic yarn, acrylic nylon, etc., it refers to man-made fibers made by the polymerization of acrylic acid, and has nothing to do with acrylic products. Among them, the acrylic sheet that people often say is the polymethyl methacrylate Polymeric Methyl Methacrylate (PMMA) sheet, which is polymerized by "Methyl Methacrylate (MMA)". Or it is extruded from acrylic pellets through an extruder. In the past, the board was commonly called plexiglass. Plexiglass is derived from the English Organic Glass, which means a PMMA board made of organic compound MMA. Its transparency and light transmittance are like glass. Because all sheets made of transparent plastics such as PS, PC, etc. or inferior recycled MMA are collectively referred to as plexiglass. For the sake of distinction, PMMA panels made of high-quality pure MMA are called acrylic panels to distinguish them from ordinary plexiglass panels.
