Vacuum blister machine pmma plastic principle raw material polymerization

The polymers obtained by polymerizing acrylic acid and its esters as raw materials are collectively referred to as acrylic resins, and the corresponding plastics are collectively referred to as polyacrylic plastics, among which polymethyl methacrylate is the most widely used. The abbreviation code of polymethyl methacrylate is PMMA, commonly known as plexiglass. It has excellent light transmission performance, can pass through more than 92% of sunlight, and ultraviolet rays reach 73.5%; it has high mechanical strength and certain heat and cold resistance. , corrosion resistance, good insulation performance, stable size, easy to form, brittle texture, easy to dissolve in organic solvents, insufficient surface hardness, easy to rub hair, can be used as transparent structural parts that require a certain strength, such as oil cups, car lights, Instrument parts, optical lenses, decorative gifts and more. Adding some additives in it can improve its performance, such as heat resistance and friction resistance. The material is widely used in the production of advertising light boxes, nameplates, etc.
