Plexiglass, English: (Polymethyl methacrylate), abbreviated as: PMMA; plexiglass chemical name is polymethyl methacrylate, is a polymer made of methacrylate polymerization. The surface is smooth, colorful, the proportion of small, strong, corrosion-resistant, moisture-resistant, light-resistant, good insulation properties, sound insulation is good. Can be divided into profiles, bar profiles, plank three.
Acrylic acid and its esters as raw materials obtained by polymerization of polymers, collectively referred to as acrylic resin, the corresponding plastic collectively referred to as polyacrylic plastic, of which the most widely used polymethylmethacrylate. PMMA abbreviation code-named PMMA, commonly known as plexiglass, has excellent light transmission, through more than 92% of the sun, up to 73.5% UV; mechanical strength, there is a certain degree of heat and cold hardiness , Corrosion resistance, good insulation properties, dimensional stability, easy molding, brittle texture, easy to dissolve in organic solvents, surface hardness is not enough, easy to scrape, can require a certain intensity of transparent structural parts, such as oil cups, lights, Instrument parts, optical lenses, decorative gifts and more. Add some additives inside can improve its performance, such as heat, friction and so on. The material is widely used in advertising light boxes, nameplate and other aspects of production.
