Teijin PC production has what requirements
Teijin PC production has what requirements
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
Teijin PC in production 时候, is has more requirements, positive is is in product production 时候, has more requirements, therefore let in PC market upper has very good effect/influence force, 首先就 is in production 时候, for/regarding production material upper has very high requirements, 我们也都知道, for/regarding this type of product 说, it in production 时候, is has different production material performance.
if is product has to in production material upper requirements, 一 会 let it in property can upper decline, but also can let 自己达 to very good property, Teijin PC就 is for/regarding production material improve/increase, therefore let 自己达 to very good property can and product quality requirements, for/regarding this 方面 说, 自然也 let it in production cost upper to improve/increase, use in this type of product 时候, 就会发现 it in price upper 面, is has improve/increase, is is in production material upper has very high requirements.
again has 一 方面, is Teijin PC in production process upper is has very high requirements, if need let product to in production process upper requirements, 首先就 is need let 自己达 to very good technology, for/regarding technology 说, is is 一 厂家 product, therefore 自己完 full has very good technology force, again has 一 方面, is 他们也 is has very good equipment, as is 一 厂家 product, in production 时候, can use low lower production equipment, 当然也 is is 他们 厂家 for/regarding this has very high requirements.
[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
