PC plastics in what industry in application 广泛
PC plastics in what industry in application 广泛
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
PC plastics in automotive to very good application, especially is it in inner parts and outer parts upper application separation 广泛, therefore it separation 广泛, 自然也 is is it has very good advantages, that it in automotive inner parts and outer parts application, is can to what advantages 呢? is this type of plastics tough property strong/high, its for/regarding automotive inner parts 说, it must need to very good tough property, other material very difficult this type of tough property, this type of can to very good 适应, this positive is it in use 时候一 is advantages.
当然, remove this advantages outer, another also has other benefits, ratio it in application 时候, also has very good strong/high degree, this 样一点也 is automotive inner and outer parts separation need, in has very more use positive is is this 一点, selection use this 一 材 material plastics, again has is in heat resistant performance, automotive 本身会 generate hot amount, other plastics, although has can to strong/high degree and tough property, is is has very good heat resistant degree, therefore by selection.
PC plastics is has very good heat resistant property, meanwhile in other 方面也 can to very good performance, therefore 自然也就 in this to very good application, 当然, also has is performance, is it property strong/high, tube/pipe is automotive outer parts, also is automotive inner parts, it in use 时候, for/regarding has very strong/high requirements, this type of plastics in use 时候, relatively large property can performance is it property strong/high, it can in this application main/primary also is performance in this upper.
[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
