1 High transparency. Plexiglass is currently the most excellent polymer transparent material, and its light transmittance is 92%, which is higher than that of glass. The tube of the sun light called the artificial sun is made of quartz because the quartz is completely transparent to ultraviolet light. Ordinary glass can only pass 0.6% of ultraviolet light, but plexiglass can pass 73%.
2 high mechanical strength. The relative molecular mass of plexiglass is about 2 million, which is a long-chain polymer compound, and the molecular chain is very soft. Therefore, the strength of plexiglass is relatively high, and the tensile and impact resistance is higher than that of ordinary glass. 18 times. There is a heated and stretched plexiglass in which the molecular segments are arranged in a very orderly manner, resulting in a significant increase in the toughness of the material. Nail is nailed into the plexiglass, and cracks are not generated on the plexiglass even if the nail penetrates. This kind of plexiglass will not break into pieces after being broken by bullets. Therefore, the stretched plexiglass can be used as a bulletproof glass and also as a canopy on a military aircraft.
3 light weight. The plexiglass has a density of 1.18 g/cm3, and the same size of material has a weight of only half that of ordinary glass and 43% of metallic aluminum (which is a light metal).
4 easy to process. Plexiglass can be cut not only by lathe, drilling by drilling machine, but also by acetone, chloroform, etc., and can be processed into large aircraft by blow molding, injection molding, extrusion and other plastic molding methods. The cockpit cover, from small to dentures and trays.
