Acrylic (loanword)

Main Applications

PMMA is to acrylic acid and its esters polymerization of polymers obtained collectively known as acrylic esters, the corresponding plastics collectively known as polyacrylic acid plastics, which to polymethyl methacrylate methyl ester is more widely used. Polymethyl methacrylate abbreviation code for PMMA, commonly known as Plexiglas, is by far the better quality of synthetic transparent materials.

PMMA is lightweight, inexpensive, easy to mold and other advantages. Its molding methods are casting, injection molding, machining, thermoforming and so on. Especially injection molding, can be mass production, simple process, low cost. Therefore, its application is becoming more and more extensive, it is widely used in instrument parts, automobile lamps, optical lenses, transparent pipes and so on.

Advantages

Acrylic is a new material that can manufacture sanitary ware after ceramics. Compared with traditional ceramic materials, acrylic, in addition to unparalleled high brightness, there are the following advantages: good toughness, not easy to break; strong repair, as long as the soft foam dipped in toothpaste can be wiped with a new sanitary ware; soft texture, no cold and harsh feeling in winter; bright colors, to meet the different tastes of the pursuit of personality. With acrylic production basin, bathtub, toilet, not only exquisite style, durable, and has the role of environmental protection, its radiation and the human body's own bone radiation level is comparable. Acrylic sanitary ware appeared earlier in the United States, has occupied more than 70% of the international market.

Disadvantages

As acrylic production is difficult, high cost, so there are a lot of low-quality and inexpensive substitutes on the market. These substitutes are also known as "acrylic", in fact, is an ordinary organic board or composite board (also known as sandwich board). Ordinary organic board with ordinary plexiglass cracked material plus pigment casting and become, low surface hardness, easy to fade, with fine sand sanding after polishing effect is poor. Composite panels only a very thin layer of acrylic surface, the center is ABS plastic, the use of thermal expansion and contraction is easy to delamination. True and false acrylic, can be identified from the sheet section of the subtle color difference and polishing effect to identify

Acrylic has a wide range of applications, can be used for test racks, patch tray.
