The principle of plexiglass
Plexiglass, abbreviated as: PMMA; plexiglass chemical name is called polymethyl methacrylate, is composed of methacrylate polymerization of polymer compounds. Smooth surface, colorful, small proportion, high strength, corrosion resistance, moisture, light fastness, good insulation properties, good sound insulation. Can be divided into three kinds of material, bar material, plate shape.
PMMA is acrylic acid and its ester polymerization obtained by the polymer collectively referred to as acrylic resin, the corresponding plastic collectively referred to as polyacrylic plastic, of which the most widely used polymethyl methacrylate. Polymethyl methacrylate abbreviation code PMMA, commonly known as plexiglass, has excellent light transmission performance, through more than 92% of the sun, ultraviolet up to 73.5%; mechanical strength is high, there is a certain heat and cold Corrosion resistance, good insulation properties, dimensional stability, easy to shape, more brittle texture, soluble in organic solvents, the surface hardness is not enough, easy to scrub, can be required to have a certain strength of the transparent structural parts, such as oil cups, Instrument parts, optical lenses, decorative gifts, and so on. Add some additives inside it can improve its performance, such as heat, friction and so on. The material is widely used in advertising light boxes, nameplates and other aspects of the production.
