Acrylic is widely used in test racks and patch trays. Suzhou PTC Optical instrument CO., Ltd provides polariscopes, that can be used to detect the stress and defects of transparent acrylic products.
Acrylic, also known as PMMA or Polymethyl methacrylate, is an important plastic polymer material that has been developed earlier. It has good transparency, chemical stability, weather fastness, easy dyeing, easy processing, and beautiful appearance. And it is widely used in the construction industry. Besides, polymethyl methacrylate products can usually be divided into cast plates, extruded plates and molding compounds.
PMMA is the polymer obtained by the polymerization of acrylic acid and its esters, which is collectively referred to as acrylic resins, and the corresponding plastics are collectively referred to as polyacrylic plastics. Among them, polymethyl methacrylate is the most widely used. The abbreviation code of polymethyl methacrylate is PMMA, commonly known as plexiglass, which is the most excellent synthetic transparent material so far.
In addition, PMMA has the advantages of light weight, low price, and easy molding. Its molding methods include casting, injection molding, machining, thermoforming and so on. Especially for injection molding, it can be mass produced, the manufacturing process is simple, and the cost is low. Therefore, its application is becoming more and more extensive. And it is widely used in instrument and meter parts, automobile lights, optical lenses, transparent pipes, etc.
Advantage
Acrylic is the best new material for sanitary ware after ceramics. Compared with traditional ceramic materials, acrylic not only has unparalleled high brightness, but also has the following advantages: good toughness and not easy to break; strong restorative, as long as the soft foam is dipped in toothpaste, the sanitary ware can be wiped new；the texture is soft, and there is no icy feeling in winter; the colors are bright, which can satisfy the individual pursuit of different tastes. Basins, bathtubs, and toilets made of acrylic are not only exquisite in style, durable, but also environmentally friendly. The radiation is almost the same as the radiation of the human bones. Acrylic sanitary ware first appeared in the United States and has occupied more than 70% of the whole international market.
Shortcoming
Due to the difficulty and high cost of acrylic production, there are many low-quality and inexpensive substitutes on the market. These substitutes are also called “acrylic”, in fact they are ordinary organic boards or composite boards (also known as sandwich boards). Ordinary organic board is cast with ordinary organic glass cracking material and pigment. The surface hardness is low, easy to fade, and the polishing effect is poor after sanding with fine sand. The composite board has only a thin layer of acrylic on the surface and ABS plastic in the middle. And due to the influence of thermal expansion and cold shrinkage, it is easy to delamination in use. Moreover, true and false acrylic can be identified from the slight chromatic aberration and polishing effect of the sheet section
