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
light expand dispersion PC plastics is in PC raw materials in add light expand agent, in this light expand agent lower, this type of plastics material products 就会呈现出 semi expand dispersion, according to light expand dispersion agent add amount different, additives pellets degree large small, and its distribution improves material use quality.
according to PC plastics use need different, this light expand dispersion agent add amount tool has very large 差异. light expand dispersion PC plastics light expand dispersion agent add amount, 就会直接 effect/influence to optical property can. according to light dispersion need different, expand dispersion material separation is full light light transmittance /雾 degree / dispersion degree, how to need to dispersion light material high light transmittance, this 无疑就 is very that issues.
this light expand dispersion PC plastics light rear, light toward 四周照射, rear 面照射 light 就会反射 to front 面, front light ultra- 临界角就会出现反射 phenomenon. different PC material 反射远离 is different, according to large 家实际 need different, need combined combined 适 材 material selection. PC expand dispersion material has good light expand dispersion 效果, relatively high material light transmittance, and to large use can force property can and other, is large 家关注 issues.
is meet/satisfy will improves PC材 material need, has light expand dispersion PC plastics 厂家就会进行专业 development, PC expand dispersion material delamination research is non important. PC材 material in 进行不断科技探索 meanwhile, also can and production technology.
light expand dispersion PC plastics dispersion pellets property can, and PC材 material polymerization process and other, can effect/influence light dispersion 射 效果, this is PC plastics will development trend.
[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

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
