The production of polymethyl methacrylate began in the 1930s and was first introduced to the market by the American company Rohm and Haas in 1936. The basic materials are sulfuric acid, hydrogen cyanide, methanol, and acetone. These are not the safest substances, but the final product is completely harmless. Methyl methacrylate is flammable, but if it burns, it will not form any harmful substances at all. The residual products are carbon dioxide and water. Key considerations when purchasing Transparent PVC Sheet
There are two types of polymethyl methacrylate commercially available: cast (GS) and extruded (XT) acrylic sheets. PVC Roll and PVC Sheet can be formed, and after the production process, the cast version is cast into a flat plate.After pouring, the extruded type is rolled into a thinner thickness. When the thickness decreases, the surface of the sheet increases, making it easier to manufacture larger PVC Sheet. The disadvantage is that the stress in the sheet increases, so the extruded sheet is prone to breakage and rupture during the processing. The so-called 'budget acrylic' is not always UV resistant, it is important to know whether the material is used for glass.
