PC plastics this type of features non more
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 我们 生 active in, can to comparison is applications, ratio 如说我们经常会 use to plastics 杯子当 in, use to this type of PC plastics 材质, but also this type of in very more can use to. its this type of PC plastics features very more can can also is very understanding. has understanding this type of features rear, 我们才 can more add this type of is what can in this or is can in this industry in use.
首先 large 家一定应该 need 知道 一点就 is it appearance, can from appearance in to, this type of transparent degree is comparison high, but also also can through color methods, will this type of 材质染 formed very more 不一样 color, therefore 说我们就 can to very more PC plastics 材质也 is more add good 看.
another this type of PC材质也 can in very more food easy in use, therefore from this 方面我们就 can this type of its is types non 常不错 材质, but also in use process in is has 任何毒害, therefore in use this type of PC plastics process in, is non safety, large can use this type of 材质.
also has this type of PC plastics also has 一 方面 benefits, that is production this type of 材质 时候, its formed shrinkage rate low, therefore non combined use made as water or is container, this is PC plastics its in 一 方面 features and advantages. but also this type of electrical appliances features its is non 常不错, above this features 都说明 PC plastics in use process in advantages.
[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
