high temperature resistance PC plastics property can stability property to how 样?
high temperature resistance PC plastics property can stability property to how 样?
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
high temperature resistance PC plastics technology improve/increase, high property can high quality product 不断问世. this product suitable scope/range relatively 广, ratio automotive industrial 就离不开, but also market demand amount increase large, product has more more applications, let large 消费者们 can use excellent price to 保质保 amount product.
is what very more industry production process 都离不开 high temperature resistance PC plastics 呢? is this product advantages very more, advantages is high temperature resistance impact resistant can force ultra- strong/high. ratio in production device table/sheet and other parts 时, need use to high temperature resistance product, high temperature resistance PC plastics is selection. 第二, high temperature resistance PC plastics product absorption rate very low, to 工人们 increase processing as difficult degree. 不, in use high temperature resistance PC plastics process in, need drying material 处理, can large large improves product quality.
第三, high temperature resistance PC plastics wear resistant degree non high, and product versus comparison, high temperature resistance PC plastics can in production process in high wear resistant degree, 不会因 is certain as process product thick degree to effect/influence, from effect/influence overall quality. is this product easy 发生熔 melt cracking, this need as in as process in, control high temperature resistance PC plastics molding conditions, 每一批塑 parts need cooling 处理, need is 处理不当导致塑 parts quality issues.
如今 high temperature resistance PC plastics use scope/range 越 越广, very more industry for high temperature resistance PC plastics has demand. is meet/satisfy market a large amount of demand, very more production 厂家不断 improves technology, improvement product quality, 专业不会令消费者吃亏 upper 当.
[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
