What is the difference between acrylic and glass?

What is acrylic?

Acrylic is also called PS board and commonly known as "organic board". Its chemical name is Polystyene, with a density of 1.02~1.08. It is a thermoplastic with relatively high transparency (the light transmittance is second only to organic glass). Excellent electrical insulation, especially high-frequency insulation. It is relatively brittle. Its impact resistance, weather resistance and aging resistance are worse than those of organic glass. Its mechanical processing properties and thermal processing properties are not as good as those of organic glass. It can withstand general chemical corrosion and chemical corrosion. It has stable properties, similar hardness to organic glass, lower water absorption and thermal expansion coefficient than organic glass, and is cheaper than organic glass.

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 and extremely high transparency. The transmittance is as high as 92~93%. It can transmit 99% of visible light and 72% of ultraviolet light. It weighs only 1/2 of ordinary glass and is resistant to shattering. Its performance is 12 to 18 times that of ordinary silica glass, its mechanical strength and toughness are more than 10 times greater than that of ordinary glass, its hardness is equivalent to that of metallic aluminum, and it has outstanding weather resistance and aging resistance. The impact strength remains unchanged at temperatures (below 100°C), has good electrical insulation properties, can withstand arcs, has good thermoplastic processing properties, is easy to process and form, has good machining properties, and can be used for sawing, drilling, milling, turning, It is processed by planing, has stable chemical properties, is resistant to general chemical corrosion, and is insoluble in water.

Plexiglass has a very beautiful appearance and has a crystal-like luster after polishing. It is also known as the "Plastic Crystal Queen". Disadvantages: The hardness is not as good as inorganic products such as steel, ceramics, and silica glass. The coefficients of water absorption and thermal expansion are large.

Uses of plexiglass: Due to its special properties, plexiglass is widely used in hotels, hotels, gymnasiums, airport terminals, bus shelters, schools, outdoor advertising light boxes, etc.
