Germany Bayer PC has very good environmental protection property performance
Germany Bayer PC has very good environmental protection property performance
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
Germany Bayer PC in use use 时候, can to very good property can, meanwhile has very good environmental protection property, 我们也都知道, for/regarding this type of product 说, it in use 时候, is need to very good environmental protection property requirements, is if product 自己不 can to environmental protection requirements 话, it in in use in, let use 者自己 in upper has 一定 伤害, is in is environmental protection 社会, therefore for/regarding types product use, it in environmental protection upper performance is separation important.
当然, Germany Bayer PC can to very good environmental protection property, is has it causes, 首先就 is in use material upper has advantages, is this type of product 本身就 is types chemical product, if product in production material upper use is low poor material, 自己就不 can to very good environmental protection property, therefore for/regarding this 方面 说, is has very good performance, it in production material improve/increase meanwhile, 自己就会达 to cost improve/increase.
if use in Germany Bayer PC 时候, 就会发现, it in price upper has improve/increase, is is in production 时候, has 自己一定 product improve/increase, 当然因 is in use 时候, has very good environmental protection property performance, therefore although it price high, for/regarding 人体造 formed 自己 伤害, therefore let use 户喜欢, remove in production material upper has improve/increase outer, in production process upper is has improve/increase.
[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
