What is plexiglass?
What is plexiglass, plexiglass is actually a chemical synthetic substance, and it also has a name called methyl methacrylate. Most people will call it plexiglass. Plexiglass is obtained by synthesizing a resin raw material. It is a kind of plastic in its own role, and Plexiglass is relatively light, but it is very hard and can be used in many places. And there is another common name for plexiglass, called acrylic, which I believe many people have heard of for a long time.
The transparency of plexiglass is very good. Experiments have shown that more than 92% of the sunlight can pass through. At the same time, the hardness is very high, and it will not be easily broken. Plexiglass is also used in car lights and other places. The corrosion resistance of plexiglass is also good, and it will not age in a short time. The price of plexiglass is also relatively affordable. And what are the properties of plexiglass?
1. High transparency
Plexiglass is an excellent polymer transparent material. The solar lamp tube of the artificial small sun is made of quartz (because quartz can completely transmit ultraviolet rays), ordinary glass can only transmit ultraviolet rays of 0.6&, but plexiglass can pass through. 73%.
2. High mechanical strength
The relative molecule of plexiglass is about 2 million, which is a long-chain polymer compound, and the chain forming the molecule is very soft. Therefore, the strength of plexiglass is high, and its tensile and impact resistance are higher than ordinary glass. 7-18 times.
There is a kind of plexiglass that has been heated and stretched. Even if the nail penetrates the plexiglass, it will not crack. After the plexiglass bullet is broken down, it will not become fragments. Therefore, the stretched plexiglass can be used as bulletproof glass, and it is also used in the canopy of military aircraft.
3. Light weight
The density of plexiglass is 1.18g/cm3, and the weight of the same size material is only half that of ordinary glass!
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 by imitation and other tools, and can also be processed into plastic molding methods such as blow molding, injection, and extrusion. Covers, everything from dentures and trays.
