Acrylic history 
 
Acrylic (ACRYLIC), the common name of special treatment of plexiglass. Acrylic research and development, dating back over 100 years of history. 1872 acrylic polymer before they were found; 1880 methacrylate polymer become known; propylene poly propionate synthesis study has been completed in 1901; 1927 the aforementioned synthesis method attempts to industrialized manufacturing; 1937 methylmalonic acid fat industrial and manufacturing development, enter the scale of manufacturing. During World War II due to the acrylic has excellent strength and toughness and transparency, be applied to the windshield of the aircraft, tanks vision mirror of the driver's cab. The birth of the world's first acrylic bathtub in 1948, marking the application of the acrylic into a new milestone.
 
Acrylic specifically refers to the pure poly (methyl methacrylate) (PMMA) material called PMMA sheet acrylic sheet. Acrylic is a lightweight, inexpensive, easy to shape and so on. It more widely applied, it is widely used in instrumentation parts, car lights, optical lenses, transparent pipeline.

Features and advantages of   acrylic
   
Weathering and acid and alkali resistance, will not put the years of sun and rain, and the formation of the phenomenon of yellowing and hydrolysis;
 
Long life, compared with other materials, products, long life for more than three years;
                  
Good light transmission, up to 92% or more, the smaller the required intensity of light, saving energy;
     
Strong impact, is 16 times that of ordinary glass, suitable for installation in the special needs of the security zone;
               
Excellent insulation properties, for a variety of electrical equipment;
   
Light weight, half the light than ordinary glass, small buildings and stand to bear the load;
     
Plasticity, changes shape, easy molding process;
                     
Recyclable rate, agree to intensify environmental awareness;
     
Easy maintenance, easy to clean, rainwater can be naturally clean, or scrub with soap and soft cloth;
       
Colorful, high brightness, are unmatched by any other material;
    
The difference between acrylic and glass
 
Acrylic character generally much stubborn than ordinary glass. Its density than ordinary glass half but unlike glass as easily broken. Its transparency is very good, crystal clear, thermoplastic and have a good, heated it will be able to arbitrarily molded glass rod, glass or glass, because of its endearing appearance and personality, so it very versatile.
 
Ordinary glass, more than 15 cm thick, will become a green one, and could not see anything across the glass. Across the 1 m thick, the acrylic can also clearly see the opposite things. Quite good because of its light transmission properties, coupled with ultraviolet light also can penetrate, so used to manufacture optical instruments.
 
Acrylic addition, an amazing performance, a bent acrylic rods, as long as the curvature of less than 48 degrees, light along it, like water through the pipes the same projection over. Light can make detours, how interesting this stunt, it becomes the treasures of the manufacture of surgical pass optical glass instruments. Therefore, doctors surgery in the operating room do not have to worry about can not see.
 
Acrylic both lightweight and tough, the chemical is quite stable, heat and plasticity, therefore its use is very extensive.
 
Appropriate to add some dyes, if the raw material of acrylic can be made according to the needs of the people of red, green and purple ... the bright lights of colored plexiglass.
 
the difference between cast acrylic sheet and extrusion board 
 
There is no difference in quality. But produced by the degradation of monomer purity is not high, the sheet metal forming, its quality, performance is poor.
 
Summary: squeeze the board use of particulate material, dissolved at high temperatures, extrusion, casting board using the MMA monomer (liquid) direct casting molding, extrusion plate shape is more flat and smooth, but because of the shape of the particles of raw materials to complete thepolymerization. Processed into a sheet structure and performance is weak and is not suitable for outdoor identify the product material only suitable for indoor products Crystal word or product such as a stent. In addition, due to extrusion of the board majority does not have UV protection function, the use of its outdoor life and casting board is quite different, the color will gradually fade and is easy to embrittlement, until rupture. The casting board is a structural polymer in the sheet processing, during which add UV absorbers, has a very high strength and UV features, outdoor life of up to 5 years to 10 years, during use the color has been bright as new.
 
Of new material acrylic board and the board the simple distinction between renewable and identification methods
 
Method for distinguishing :
 
Of new material transparent acrylic plate: A: light transmittance greater than 92%, the section was transparent and colorless B: excellent UV resistance, outdoor 5-8 years without fading, loss of light, yellowing, cracking and C:high surface hardness, aluminum and brass quite D: anti-cracking and resistance to chemicals, excellent E: high-quality protective film to provide adequate protection
 
Recycled material regeneration board transparent acrylic plate: A: transmittance of less than 86%, the cross section at the yellow B: UV resistance is very poor, up to six months will be yellowing under sunlight prone to crack C: low surface hardnesseasy to scratch D: easy to crack E: the protective film of poor quality, easy to aging deterioration.
 
Methods of identification:
 
Pure new material of acrylic plate: A: renewable plate appearance of pure color, especially from the cross-section. B: excellent surface hardness and scratch resistance, cutting no stimulus odor. C: thermoforming heating is not easy to produce bubbles and deformation. D: adaptive stability of the paint, ink. E: burning, no blistering no smoke odor stimulus.
 
Back to the new material regeneration board: A: regeneration plate appearance of yellowing. B: the surface is easily scratched, cut a stimulus odor. C: thermoforming heating, prone to bubble deformation. D: paint, ink-sensitive, prone to crazing or cracks. E: burning, blistering issued black smoke and pungent odor.
 
On the market - acrylic history (market prospects)
 
The broad the plexiglass market development prospects: plexiglass early development of a thermoplastic, transparency, stability and weather resistance, easy to stain, easy processing, beautiful appearance, has been widely applied in the construction industry.
 
In architecture, the plexiglass is mainly used in the lighting body, roof, roof, stairs and interior walls shield and so on. In recent years, the plexiglass in respect of highways and high-level road lighting lamp shade and automotive lighting is also quite fast. With the construction of the big city restaurants, hotels and senior housing, the rapid development of light body, using plexiglass extrusion plate made of light body and the overall structure of high strength, light weight, high transmittance and good safety performance, and inorganic glass lighting devices, compared with a strong advantage.
 
In sanitary ware, plexiglass can be made to the bathtub, washbasin, dressing table and other products. Plexiglass bathtub has a luxurious appearance and a sense of depth, easy to clean, high strength, light weight and comfortable to use and so on, has been widely used in recent years.
 
Currently, the U.S. and Japan have made a mandatory requirement in the law, schools and kindergartens building must be used plexiglass. With the continuous improvement of our laws, it is expected that in the near future will also make provision for. At the same time, all over the country to accelerate the pace of urban construction, plexiglass street signs, advertising light boxes and phone booths will also be large numbers, thus plexiglass great room for development, market prospect is very broad.
