Introduction to plexiglass
PMMA is a polymer obtained by polymerizing acrylic acid and its esters, collectively referred to as acrylic resin. The corresponding plastics are collectively referred to as polyacrylic plastics, of which polymethyl methacrylate is the most widely used. Polymethyl methacrylate, abbreviated as PMMA, commonly known as plexiglass, has excellent light transmission properties, can pass more than 92% of sunlight, and has an ultraviolet ray of 73.5%. It has high mechanical strength and has certain heat and cold resistance. Corrosion resistance, good insulation performance, stable size, easy to shape, brittle texture, easy to dissolve in organic solvents, insufficient surface hardness, easy to rub, can be used for transparent structural parts with certain strength, such as oil cups, lamps, Instrument parts, optical lenses, decorative gifts and more. Adding some additives to it can improve its performance, such as heat resistance and friction resistance. It is by far the most excellent in the synthesis of transparent materials. At present, the material is widely used in the production of advertising light boxes, nameplates and the like.
