PMMA ZK6BR 德国赢创德固赛聚甲基丙烯酸甲酯（polymethylmethacrylate)，简称PMMA），又称做压克力、亚克力（英文Acrylic）或有机玻璃、Lucite（商品名称），在台湾称做压加力，在香港多称做阿加力胶，具有高透明度，低价格，易于机械加工等优点，是平常经常使用的玻璃替代材料。
PMMA ZK6BR chemical properties:1, due to its larger branchedchain, the viscosity of poly (methyl methacrylate is higher,therefore used in hot working method processing speed is slow,organic glass not only can use lathe cutting, drilling, drillingmachine and the bond into various shapes such as with acetone,chloroform, can also blow molding, plastic molding methods such asinjection, extrusion processing into large canopy to aircraft,small to the false teeth and a variety of products such as plates.Cyanoacrylate, dichloromethane, or chloroform, for example, candissolve plexiglass slightly, and two plexiglass pieces can then befirmly glued together. To produce 1 kilogram of PMMA, you needabout 2 kilograms of oil. In the aerobic condition, PMMA starts toburn at 458°C, producing carbon dioxide, water, carbon monoxide andsome low-molecular compounds including formaldehyde.
PMMA ZK6BR Germany win win degussa physical performance:1. Thedensity of PMMA is lower than that of glass: the density of PMMA isabout 1.15-1.19g /cm3, half of that of glass (2.40-2.80g /cm3) and43% of that of metal aluminum (belonging to light metal).2, PMMA'smechanical strength is high: PMMA's relative molecular mass isabout 2 million, is a long chain of polymer, and the formation ofmolecular chain is very soft, therefore, PMMA's strength isrelatively high, the ability to resist tension and impact is 7 ~ 18times higher than ordinary glass. One kind of plexiglass has beenheated and stretched, in which the molecular segments are arrangedin such a sequence that the toughness of the material issignificantly improved. If a nail is driven into the plexiglass, itwill not crack even if the nail penetrates. The plexiglass alsodoes not break into pieces when it is hit by a bullet. Therefore,stretch treated PMMA can be used as bulletproof glass and also as acanopy on military aircraft.
