Plexiglass, also known as acrylic or acrylic, called PMMA. It has the advantages of high transparency, low price and easy machining. It is a glass substitute material that is often used frequently. Its chemical name is polymethyl methacrylate. Plexiglass has good transparency and outstanding aging resistance; its specific gravity is less than half of that of ordinary glass, and its resistance to chipping is several times higher; it has good insulation and mechanical strength; it is good for acid, alkali and salt. Has strong corrosion resistance; and easy to process; can be bonded, saw, planed, drilled, engraved, ground, screen printing, sandblasting and other manual and mechanical processing, can be bent into various organic after heating Glass product.
Plexiglass has the advantages of light weight, low cost, and easy molding. Its molding methods include casting, injection molding, machining, and hot bending. In particular, injection molding can be mass-produced, with simple process and low cost. Therefore, its application is becoming more widespread. Acrylic is the best new material that can be used to make sanitary ware after ceramics. Compared with traditional ceramic materials, acrylic has the following advantages: in addition to unparalleled high brightness, it has the following advantages: good toughness and not easy to break; strong repairability, as long as the soft foam is used to remove the toothpaste, the sanitary ware can be wiped fresh; the texture is soft, no winter Cool and biting; colorful, can meet the personality pursuit of different tastes. Because acrylic production is difficult and costly, there are many low-cost and low-cost substitutes on the market. These substitutes are called "acrylic" and are actually ordinary organic boards or composite boards. Ordinary organic plates are cast with ordinary plexiglass cracking materials and pigments. The surface hardness is low and easy to fade. After polishing with fine sand, the polishing effect is poor. The composite board has only a thin layer of acrylic on the surface, and the middle is ABS plastic, which is easily delaminated by the expansion and contraction during use. True and false acrylic, which can be identified from the subtle chromatic aberration and polishing effect of the sheet section. Plexiglass products are widely used: 1. Building applications: windows, soundproof doors and windows, lighting hoods, telephone booths, etc. 2. Advertising applications: light boxes, signboards, signs, display racks, etc. 3. Traffic applications: trains, cars, and other vehicle doors and windows, etc. 4. Medicine Application: Baby incubator, various surgical medical instruments, civilian products: bathroom facilities, handicrafts , cosmetics, brackets, aquariums, etc. 5. Industrial use: instrument surface plates and covers, etc. 6. Lighting applications: fluorescent lamps, chandeliers, Street lamp cover, etc. 7. Home application: fruit plate, tissue box, acrylic art painting and other household daily products.
Characteristics and advantages of plexiglass products:
Acrylic has a high transparency and a light transmittance of 92%. It has the reputation of "plastic crystal". It has excellent weather resistance, especially for outdoor use, it is the crown of other plastics, and has good surface hardness and luster. It has large processing plasticity and can be made into various shapes and products. The other types of plates are rich in color (including translucent swatches), and the other feature is that the slabs still maintain high transparency.
