Teijin PC has production process upper improve/increase
Teijin PC has production process upper improve/increase
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
versus ratio other PC product 说, Teijin PC in production 时候, is has in production process upper improve/increase, it in use 时候, can to property can, 美观, lifespan and other and other very more improve/increase, is is in production 时候, has very good production process improve/increase, 当然他们 can let 自己达 to very good production process improve/increase, is has 自己一定 causes, that its in causes is what 呢? 首先就 is in equipment upper has very good performance.
我们也都知道, for/regarding in large industrial lower, if 自己没 has very good equipment 话, is can let 自己达 to very good production process improve/increase, therefore 首先就 is has in this performance, is product if need performance 出自己 in production process upper performance, is need to surface upper gloss property, Teijin PC自己 has very good equipment performance, therefore let 自己达 to very good performance, remove this 方面之 outer, is has other 一 方面 causes.
also has 一 方面, is Teijin PC in overall as upper is has very good performance, 我们也都知道, make is use again good equipment, is if 自己没 has very good as 话, is can let product to very good equipment requirements, therefore can let 自己达 to very good performance, is is has in technology upper property, rear 一点, is in production material upper has very high requirements, is 决定一 product in property can upper performance, also is it in production material upper performance.
[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
