Korea 三星PC use has very good stability property
Korea 三星PC use has very good stability property
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
Korea 三星PC in use use 时候, is has very good stability property performance, 我们也都知道, its product in use 时候, can can to very good property can, meanwhile can can performance very long use lifespan, is and it stability property has 一定 关系, therefore is from 哪 角 degree 说, use is it has very good stability property performance, this type of product is to very good this 方面 效果, therefore it in use 时候, 才会受 to very more use good 评.
当然, Korea 三星PC can to very good stability property performance, is has 他们自己 causes, that its in causes is is what 呢? is is in production 时候, has very good technology can force, enterprise if need let product to very good 效果, 首先就 is need in technology upper to very performance, 而他们就 is 自己首先 has very good technology performance, therefore 他们才会 let product to very good stability property performance.
again has 一 方面, is Korea 三星PC in product production upper has very good equipment advantages, for/regarding this type of product 说, it in production 时候, can can use 手工 进行 production, must need use equipment, for/regarding equipment 说, different 厂家, in equipment upper 面, is has different performance, is in equipment upper has very good property performance, therefore let product has very good property can performance, 自然也就达 to it very good product stability property 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
