Acrylic Open Category: Materials, Acrylic The word "acrylic" may sound strange to humans because it is a new term that has appeared on the mainland in the last two years. Until 2002, it was gradually recognized by a few people in the advertising industry, furniture industry, and handicraft industry.
1."Acrylic" is a transliteration of foreign words, English is ACRYLIC, it is a chemical material. The chemical name "PMMA" is an allyl alcohol, commonly known as "specially treated plexiglass". In the application industry, its raw materials generally appear in the form of granules, plates, pipes and the like.
2. Acrylic sheet and plexiglass "Plexiglas" from English Organic Glass. In recent years, in all areas, all the plates made of transparent plastic are collectively referred to as plexiglass. In fact, this is wrong. Acrylic refers to pure polymethyl methacrylate (PMMA) materials, while PMMA plates are called Acrylic sheet.
3. Characteristics and advantages of acrylic sheet Acrylic has high transparency and 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.
4. History of Acrylic ACRYLIC, the common name for special treatment of plexiglass. Acrylic research and development has a history of more than 100 years. The polymerization of acrylic acid was first discovered in 1872; the polymerizability of methacrylic acid was known in 1880; the synthesis of propylene polypropionate was completed in 1901; the industrial synthesis was attempted in 1927 using the aforementioned synthesis; the methyl acid ester industry in 1937 The manufacturing development was successful, and thus entered the scale manufacturing. Due to the excellent toughness and light transmission of acrylic during World War II, first of all, it was applied to the windshield of the aircraft and the sight glass of the tank driver's cab. The birth of the world's first acrylic bathtub in 1948 marked the beginning of a new milestone in the application of acrylic.
5. Use of Acrylic PMMA has the advantages of light weight, low cost and easy molding. Its forming methods include casting, injection molding, machining, and thermoforming. In particular, injection molding can be mass-produced, with simple process and low cost. Therefore, its application is becoming more and more extensive, and it is widely used in instrumentation parts, automobile lamps, optical lenses, transparent pipes, and the like.
