Acrylic is also known as PS plate commonly known as "organic plate", chemical name Polystyene polystyrene, density 1.02 ~ 1.08 is a thermoplastic, high transparency (transmittance is second only to plexiglass), has excellent electrical insulation, high Frequency insulation is especially good, the quality is brittle, impact resistance, weather resistance and aging resistance are worse than that of organic glass. The mechanical processing properties and hot processing properties are not as good as plexiglass.
It can resist general chemical corrosion, chemical stability, hardness and plexiglass. Similarly, the water absorption rate and thermal expansion coefficient are smaller than that of plexiglass, and the price is lower than that of plexiglass. The chemical name Poly(methyl methacrylimide) polymethyl methacrylate is polymerized from methyl methacrylate monomer MMA. It is a thermoplastic with a density of 1.19~1.20, high transparency, transmittance of 92~93%, 99% visible light, 72% UV light, 1/2 weight of ordinary glass, and resistant to chipping. The performance is 12~18 times of ordinary silicon glass, the mechanical strength and toughness are more than 10 times higher than ordinary glass, the hardness is equivalent to metal aluminum, with outstanding weather resistance and aging resistance, at low temperature (-50~60 °C) and higher Temperature (below 100 °C), constant impact strength, good electrical insulation, arc resistance, good thermoplastic processing properties, easy processing and molding, good machining properties, sawing, drilling, milling, car, Planed for processing, stable chemical properties, resistant to general chemical corrosion, insoluble in water.
Plexiglass has a very beautiful appearance, polished with a crystal-like luster, alias "plastic crystal queen". Disadvantages: Hardness is not as good as inorganic products such as steel, ceramics and silica glass. The coefficient of water absorption and thermal expansion are large. Use of plexiglass: Plexiglass is widely used in hotels, hotels, stadiums, airport terminals, bus shelters, schools, outdoor advertising light boxes, etc. due to its special properties.
