医疗器材
可作医疗用途的杯、筒、瓶以及牙科器械、药品容器和手术器械，甚至还可用作人工肾、人工肺等人工脏器。
其它方面
建筑上用作中空筋双壁板、暖房玻璃等;在纺织行业用作纺织纱管、纺织机轴瓦等;日用方面作奶瓶、餐具、玩具、模型、LED灯外壳和手机外壳等。
制备
聚碳酸酯纺织纱管的生产，选用光气法生产的PC为原料，其中新料为80%，再生料为20%。其生产工艺流程如下:
配料→干燥→注射→修整→抛光→热处理→制品。
烘箱干燥温度115-120℃， 16-20小时，物料在料盘上厚度为30毫米以下，使树脂含水量在0.03%以下。
料筒三区温度为200-220、 250-280、260-290℃，喷咀温度比料筒稍低些，低5-10℃。注射压力60-100MPa，成型周期25秒，热处理温度115-120℃，1小时，要采用倒悬式进行热处理。
该纱管比木质纱管使用寿命长3倍、尺寸稳定、耐候性好，不起毛、光洁度好，能提供各种颜色的纱管，便于搞好班组经济核算。
对于废旧再生PC料，还可以进行增韧处理，顶替新料使用。可在再生PC料中，共混少量的尼龙树脂，或高抗冲聚苯乙烯树脂，可使制品的冲击强度提高1倍以上，弯曲强度也有改善，对树脂的加工性能、表面光铎均有所提高了很多。
此外，由于尼龙在熔融时粘度极低，能对共混体系中的颜料有优良的浸润包复作用，破坏了颜料较子的聚集结构，增加了颜料分散性，为此可降低颜料用量的20%。
Use ofoptical lighting for manufacturing large lampshade, protectiveglass, optical instruments around the eyepiece tube, etc. . Alsocan be widely used in aircraft transparent materials. Polycarbonateis an excellent E (120 ° C) class insulating material forelectrical and electronic appliances. It is used for manufacturinginsulating connectors, coil frames, tube pedestals, insulatingsleeves, telephone case and parts, battery case of Miner's lamp,etc. . It can also be used to make parts with high dimensionalaccuracy, such as compact discs, telephones, computer, videorecorders, telephone switches, signal relays and othercommunication e Polycarbonate thin film is also widelyused as capacitors, insulating bags, audio tapes, color video tape,etc. . Mechanical e for the manufacture of various gears,rack, worm, worm, bearing, Cam, bolt, lever, crankshaft, Ratchet,it can also be used as housing, cover and frame of some mechanicale The medical apparatus can be used as cups, tubes,bottles, dental instruments, medicine containers and surgicalinstruments for medical purposes, and even as artificial organssuch as artificial kidneys and artificiallungs. In other aspects, it is usedas hollow rib double wall panel, greenhouse glass, etc. in thetextile industry as textile yarn tube, textile machine bush, etc.Daily use for baby bottles, tableware, toys, models, LED lamp shelland mobile phone shell. PC produced by phosgene method is used asraw material in the production of polycarbonate textile yarn tube,in which the new material is 80% and the recycled material is 20% .The production process is as follows: batching → drying → injection→ dressing → polishing → heat treatment → products. The dryingtemperature of oven is 115-120 ° C, 16-20 hours, the material isless than 30 mm in thickness on the material tray, so that themoisture content of resin is less than 0.03% . The temperature ofthe three sections of the cylinder is 200-220,250-280,260-290 ° c.the temperature of the nozzle is slightly lower than that of thecylinder, 5-10 ° C lower. Injection Pressure 60-100 mpa, moldingcycle 25 seconds, heat treatment temperature 115-120 ° C, 1 hour,to use inverted suspension heat treatment. Compared with woodenbobbin, this kind of bobbin has three times longer service life,stable size, good weather resistance, no hair, good smoothness, andcan provide all kinds of color bobbin, which is convenient for TeamEconomic Accounting. For the waste recycled PC material, it canalso be toughened to replace the use of new materials. The impactstrength of the product can be increased by more than 1 times andthe bending strength can be improved by blending a small amount ofnylon resin or high impact polystyrene resin in the recycled PCmaterial, on the resin processing performance, the surface lighthas improved a lot. In addition, because of the very low viscosityof nylon in melting, it can have an excellent wetting and coatingeffect on the pigment in the blend system, which destroys theaggregation structure of pigment and increases the dispersion ofpigment, this can reduce the amount of pigment by 20% .
