Acrylic Board research and development and use, from today has been more than 100 years of history. 1880 polymerization of methacrylic acid was known; in 1901, the synthesis of polyacrylate Ester was completed; 1927 the use of the synthesis method to try industrial manufacturing; 1937 methyl methacrylate industry manufacturing development success, from this into large-scale manufacturing, because of its excellent toughness and light transmittance, During World War II, when used in aircraft windshield, tank vision mirror, and so on, the most common mobile phone screen is made of optical grade acrylic.
Acrylic board is mainly used for carving, decoration, handicraft production, extrusion type is usually used for advertising signs, light boxes and other production. PMMA has the advantages of light weight, low price and easy forming. Its molding method has casting, injection molding, machining, thermoforming and so on. In particular, injection molding, can be high-volume production, simple process, low cost. Therefore, its application is becoming more and more extensive, it is widely used in instrumentation parts, automobile headlights, optical lenses, transparent pipes and so on.
In the construction, plexiglass is mainly used in lighting bodies, roofs, roof, staircases and indoor wall guard panels. Plexiglass is also very quick to use in the lighting of highways and advanced roads and in automotive lighting. With the construction of hotels, guesthouses and advanced residences in big cities, the daylighting has developed rapidly, and the daylighting body made of plexiglass has the advantages of high overall structure strength, light weight, high transmittance and good safety performance, and has great superiority compared with the inorganic glass daylighting device.
