台湾奇美PMMA高透明

The application of PMMA plastic raw materials automotive industry (signal light equipment, instrument panel, etc.) , the pharmaceutical industry (blood storage containers, etc.) , industrial applications (DVD, light scattering) , buttons for electronic products (especially transparent ones) . Daily consumer goods (beverage cups, stationery, etc.) PMMA plastic properties brief: Poly(methyl methacrylate) , PMMA also known as Plexiglass, acrylic (sub-afterburner) . As the name suggests, it is famous for its good optical transparency. It not only has a very high light transmittance (92%) , and high mechanical strength, light weight, UV resistance and outdoor aging excellent electrical properties. PMMA is the lack of surface hardness, poor heat resistance, impact strength is not high, especially for notch impact sensitivity. The properties of the modified PMMA become more excellent. PMMA PLASTIC APPLICATIONS: widely used: Optical instruments: The production of a variety of optical lenses, such as glasses, magnifiers, lenses and laser scanning control of slow-moving video tape and so on. Stationery and daily necessities: make all kinds of drawing tools, teaching models, marking shields, lamps, all kinds of penholder, buttons, hairpins, Candy Boxes, soap boxes, containers and other daily decorations. CONSTRUCTION: Indoor and outdoor lighting and non-lighting signal display, ceiling lighting equipment, advanced decorations (such as sculpture, etc.) , furniture, clapboard materials. The outer cover of the solar collector and the sun-closed bath bed operated by the indoor ultraviolet lamp can be made into colorful organic glass bath crock and Washbasin. Other aspects: can be used as medical devices, such as prostheses, dentures, medical light basic materials. It can also be used as a substitute for Inorganic Silica glass. Windshields for cosmic instruments, indicator lampshades, surface coverings, automobiles and motorcycles.

PMMA塑胶原料的化学性能

由于其较大的枝链，聚甲基丙烯酸甲酯的黏度较高，因此在使用热加工方法时加工速度比较慢，有机玻璃不但能用车床进行切削，钻床进行钻孔，而且能用丙酮、氯仿等粘结成各种形状的器具，也能用吹塑、注射、挤出等塑料成型的方法加工成大到飞机座舱盖，小到假牙和牙托等形形的制品。氰基丙烯酸酯、二氯甲烷或氯仿等都可以轻微地溶解有机玻璃，然后可以把两块有机玻璃牢固地黏合在一起。生产1公斤的PMMA，需要大约2公斤的石油。在有氧的情况下，PMMA在460°C开始燃烧，燃烧后生成二氧化碳、水、一氧化碳及包括甲醛在内的一些低分子化合物。

PMMA塑胶原料注塑模工艺条件

干燥处理：PMMA具有吸湿性因此加工前的干燥处理是必须的。建议干燥条件为90C、2~4小时。

熔化温度：240~270C。模具温度：35~70C°

注射速度：中等
