PMMA raw material characteristics and using application

Characteristics of raw materials:

   It is colorless and transparent, and its light transmittance is 90%---92%. It has strong toughness and is 10 times larger than silicon glass.

   Excellent optical, insulating, processability and weather resistance.

   It is dissolved in organic solvents such as carbon tetrachloride, benzene, toluene dichloroethane, chloroform and acetone.

   It has high transparency and brightness, good heat resistance, and is tough, hard and rigid. The heat distortion temperature is 80 °C and the bending strength is 110Mpa.

The density is 1.14-1.20g/cc, the deformation temperature is 76--116°C, and the molding shrinkage is 0.2-0.8%.

   Linear expansion coefficient 0.00005—0.00009/°C, heat distortion temperature 68--69°C (74--107°C)

Usage applications:

   PMMA has the advantages of light weight, low cost and easy molding. Soluble in organic solvents such as anisole, can form a good film and good dielectric properties, can be used as a dielectric layer with an airport effect tube.

   Its molding 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 increasingly widespread, it is widely used in instrumentation parts, automotive lights, optical lenses, transparent pipes.

The application of plexiglass acrylic (acrylic) in the construction industry, plexiglass acrylic (acrylic) is mainly used in architectural lighting, transparent roof, roof, telephone booth, stairs and room wall guards; Sanitary ware has bathtubs, washbasins, dressing tables and other products. The application development of highways and high-grade road lighting covers and automotive lamps is also quite fast. Among them, the market for building lighting, bathtubs, street advertising light boxes and telephone booths has grown rapidly, and the future development space is large, and the market prospect is very broad.

    With the construction of hotels, hotels and high-end residential buildings in major cities, China's architectural lighting bodies have developed rapidly. The illuminating bodies made of plexiglass acrylic (acrylic) extruded sheets have high overall structural strength, light weight and light transmission. The special advantages of high rate and high safety performance have great advantages compared with inorganic glass lighting devices.

The United States and Japan have made mandatory provisions in the law, and glass for primary and secondary schools and kindergartens must use plexiglass acrylic (acrylic). With the continuous improvement of Chinese laws and regulations, it is expected that in the near future, Chinese law will also stipulate that plexiglass acrylic (acrylic) must also be used in primary and secondary schools and kindergarten building glass. At the same time, the pace of urban construction has accelerated in various parts of China. Street signs, advertising light boxes and telephone booths have appeared in large numbers, and a considerable part of the materials used are plexiglass acrylic materials.
