PC/ABS plastics is types general purpose engineering plastics
PC polycarbonate (PC) | technology 文章 | Daoqin plastics raw materials
本文 will detailed introductionpolycarbonate (PC) （PC）material property can features, application areas and processing process, is material selection and product design provide 参考.
detailed introduction
active in 我们经常 in use or in plastics products in is non more, comparison Common is PC/ABS plastics, this type of its is need use to, ratio 如说我们 day in use to water is using/adopting PC/ABS plastics this type of 材质, but also this type of is safety and 无毒, therefore large can non 常放心 use this type of 材质, another also has 一 方面, is large need attention/notes, that is use this type of water 杯, its is can hot water, is this type of 材质并不 is types can high temperature resistance plastics, therefore 说并不适 combined hot water, generally use this type of made formed water can as is cold water use, or can as is 漱口杯 use, this use is positive 确.
but also in in this use this type of PC/ABS plastics 材质 方 also is comparison more, therefore in production PC/ABS plastics this type of 材质 厂家, 自然也就变 more add more 起, large for/regarding this type of function, 专业也 is 专业不 can overlook. large for/regarding PC/ABS plastics this type of understanding degree add deep, 也一定会 has more add more understanding this type of 材质.
PC/ABS plastics this type of 材质, in in this stage/phase in, already formed is large engineering plastics in growth speed degree non fast general purpose engineering plastics 之一, therefore in very more industry and field/area in, 我们也都 can to PC/ABS plastics this type of 材质, positive in 不断发挥出 non large function, large for/regarding this type of obvious more add understanding, future this type of 材质才会发挥出 more add large function.
[材 material basic parameters ]
| density | 1.20 g/cm³ |
| 玻璃化转变 temperature degree | 147°C |
| heat deflection temperature (HDT) | 130~140°C |
| tensile strength | 55~75 MPa |
| notched impact strength | 600~850 J/m |
| light transmittance | 88~91% |
| flame retardant rating | UL 94 V-2 |
| molding shrinkage | 0.5~0.7% |
core advantages
- high transparency degree: light transmittance can 达89% above, is excellent transparent engineering material
- 卓越 impact resistant property: notched impact strength high 达600-850 J/m, is 普通玻璃 250倍
- excellent dimensional stability: molding shrinkage low （0.5-0.7%）, products dimensions 精确
- wide use temperature degree scope/range: can in -60°C至120°C scope/range inner long use
- excellent electrical insulation property can: volume resistivity high, suitable for electronics electrical field/area
- good flame retardant property: tool has self-extinguishing property, can UL 94 V-2 grade
application areas
electrical outer housing/shell, machine outer housing/shell, LED lamp covers, light 盘, connectors, 开关
lamp covers, table/sheet sheet/plate, 保险杠, 天窗, 车窗玻璃
cationic light sheet/plate, light sheet/plate, 隔音屏障, safety anti 护窗
liquid device, device 械, bottle, 婴儿保育箱
眼镜 sheet/slice, versus machine 镜头, micro sheet/slice, light
injection molding processing process
- drying 处理: 120°C drying 4-6 small 时, moisture content ≤0.02%
- material temperature degree: 260~310°C（ according to molecular weight adjustment ）
- mold temperature degree: 80~120°C（ high mold temperature can obtain more good surface quality ）
- injection pressure: 80~140 MPa
- injection speed degree: in and other slow, 避免喷射 and scorching/burn marks
- precautions: PC for 缺口敏感, products design 应避免尖角
