Explanation

It is a popular name, and its chemical name is polymethyl methacrylate. It is a macromolecule compound formed by polymerization of methyl methacrylate. It has the advantages of high transparency, low price, easy machining, etc. It is a commonly used glass substitute for materials. It has excellent light transmittance, can penetrate more than 92% of visible light, and can reach 73.5% of ultraviolet light. It has high mechanical strength, certain heat and cold resistance, corrosion resistance, good insulation performance, stable size, easy molding, brittle texture, easy to dissolve in organic solvents, insufficient surface hardness, and easy to scratch, Can be used as transparent structural components with certain strength requirements, such as oil cups, car lights, instrument parts, optical lenses, decorative gifts, etc. Adding some additive in it can improve its performance, such as heat resistance, friction resistance, etc. organic glass can not only be cut by lathe and drilled by drilling machine, but also be bonded into various shapes with acetone, chloroform and other tools. It can also be processed into various products, ranging from airplane canopy to demure and denture base, by plastics molding methods such as blow molding, injection and extrusion. On the other hand, the materials is widely used in the production of advertising light boxes, nameplates, etc; Due to its stability, it also has certain applications in the medical field.
