resistant 刮花PC plastics tool has what use features 呢?
resistant 刮花PC plastics tool has what use features 呢?
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
in understanding resistant 刮花PC plastics features front, large need understanding what is PC plastics. upper, this type of PC plastics is polycarbonate (PC), material separation in has polymer/macromolecule polymer, according to large need different, this type of PC plastics is tool has different classification.
this type of PC材 material use features how to 嫩? resistant 刮花PC plastics strong/high degree is very high, plastics tool has very strong/high impact resistant can force, in ensure PC材 material strong/high degree meanwhile, is 兼顾 一定 tough property. and market upper its it PC材 material versus ratio, this type of material use features is separation 专业, PC plastics for/regarding temperature degree and gas conditions use can force is very strong/high.
resistant 刮花PC plastics transparent degree is very high, according to large use need different, can versus 应 材 material color 处理, this in meet/satisfy large use need meanwhile, PC plastics use features 也不会发生任何 改变. is tool has material PC plastics use need 朋友, large need according to 自己 实际 need selection.
versus very more 朋友都担心PC plastics hot cold shrink 效应, upper, use 者根本没 has necessary this, this type of PC plastics use stability property is very good, resistant 刮花PC plastics generally lower, 不会出现任何 dimensions upper 变化. and market upper that poor material versus ratio. this type of PC材 material is has property, is in environmental protection plastics material, made as production process in, is is requirements production.
知道 resistant 刮花PC plastics 吗? this type of material use features is very high, this good use features, plastics is to very more use can.
[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
