In our daily life, we often use finished products made of acrylic. So, are you aware of its main uses and advantages and disadvantages? The following will be explained by professionals in the acrylic industry.
PMMA is a polymer obtained by the polymerization of acrylic acid and its esters, collectively referred to as acrylic resins, and the corresponding plastics are collectively referred to as polyacrylic plastics, of which polymethyl methacrylate is widely used. The abbreviation code of polymethyl methacrylate is PMMA, commonly known as plexiglass, and it is the best synthetic transparent material so far.
PMMA has the advantages of light weight, low price, and easy molding. Its molding methods include casting, injection molding, machining, thermoforming, etc. In particular, injection molding can be produced in large quantities, with simple manufacturing process and low cost. Therefore, its application is becoming more and more extensive. It is widely used in instrumentation parts, automobile lights, optical lenses, transparent pipes, etc.
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 called sandwich boards). Ordinary organic board is cast with ordinary plexiglass cracking material and pigment, with low surface hardness, easy to fade, and poor polishing effect after sanding with fine sand. The composite board has only a very thin layer of acrylic on the surface and ABS plastic in the middle. It is easy to delamination due to thermal expansion and contraction during use. True and false acrylic can be identified from the slight color difference and polishing effect of the sheet section
Acrylic is a new material that can make sanitary ware after ceramics. Compared with traditional ceramic materials, besides high brightness, acrylic has the following advantages: good toughness, not easy to break; strong repairability, 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 cold in winter Sharpness; bright colors, which can meet the individual pursuit of different tastes. The use of acrylic to make basins, bathtubs, and toilets is not only exquisite in style, durable, but also environmentally friendly. Its radiation is almost the same as that of the human body's own bones. Acrylic sanitary ware appeared in the United States as early as, and has occupied more than 70% of the entire international market.
