The benefits of using plexiglass (acrylic)
1.The aesthetics of plexiglass 2. The visual effect of plexiglass 3. The light transmittance of plexiglass 4. The impact resistance of plexiglass 5. The durability of plexiglass 6. The weather resistance of plexiglass 7. The flame resistance of plexiglass 8. Energy saving of plexiglass 9. Rationality of plexiglass. Plexiglass is the popular name of PMMA, also known as acrylic (Acrylic). From this name, you may not know what kind of material it is, nor what elements it is composed of. The chemical name of this polymer transparent material is polymethyl methacrylate. The acrylic sheet that people often say is polymethyl methacrylate (PMMA) sheet, which is polymerized by methyl methacrylate monomer (MMA)to make.
The characteristics of plexiglass
1.High transparency. Organic glass is the best polymer transparent material at present, with a light transmittance of 92%, which is higher than that of glass. The tube of the sun lamp called the artificial sun is made of quartz, because quartz is completely transparent to ultraviolet rays. Ordinary glass can only transmit 0.6% of ultraviolet rays, but plexiglass can transmit 73%.
2.High mechanical strength. The relative molecular mass of plexiglass is about 2 million. It is a long-chain polymer compound, and the chain forming the molecule is very soft. Therefore, the strength of plexiglass is relatively high, and its tensile and impact resistance is 7~7 higher than that of ordinary glass. 18 times. There is a kind of plexiglass that has been heated and stretched, in which the molecular segments are arranged in a very orderly manner, which significantly improves the toughness of the material. Nails are used in this plexiglass, and even if the nails penetrate, the plexiglass will not crack. This kind of plexiglass will also not break into pieces after being penetrated by a bullet. Therefore, stretched plexiglass can be used as bulletproof glass and also as canopy on military aircraft.
3.Lightweight. The density of plexiglass is 1.18kg/dm3, the same size material, its weight is only half of ordinary glass, 43% of metal aluminum (belonging to light metal).
4.Easy to process. Plexiglass can not only be cut with a lathe and drilled with a drilling machine, but also can be bonded into various shapes of appliances with acetone, chloroform, etc., and can also be processed into plastic molding methods such as blow molding, injection, and extrusion. Cockpit covers, everything from dentures to dental trays.
