Taiwan Formosa Chemicals PC has 自己 what advantages
Taiwan Formosa Chemicals PC has what advantages
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
Taiwan Formosa Chemicals PC as is types engineering plastics, it in use 时候, has very good very good advantages, that it in use 时候, is has what advantages 呢? 首先就 is it in use 时候, has very good transparent degree, 我们也都知道, for/regarding types product 说, it in use ring lower, is need let it to in transparent degree upper requirements, ratio electronics, machine product and other and other, is has this 样 估 very.
again has 一 方面, is Taiwan Formosa Chemicals PC in hardness upper 面, is has advantages, is it in use 时候, is has 一 仪 table/sheet, or is machine upper in use it 时候, is has in hardness upper requirements, if has hardness requirements, it in use 时候, can to very good property, in other product upper in this type of product use 时候, 首先也 is need let it to in hardness upper need to requirements.
but also Taiwan Formosa Chemicals PC in 自己 自己 use lifespan upper 面, is has very good performance, it can to very good use lifespan requirements, is 自己一者 has very good weather resistance, 我们也都知道, has product in use lifespan upper decline, is is 自己没 has to very good weather resistance, it can to very good weather resistance requirements, in product upper performance 说, is has very good temperature degree property, positive is is this 样, let it has very good use lifespan 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
