flame retardant PC principle and catalytic system
flame retardant PC principle and catalytic system
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
PC is types mechanical properties especially good plastics products, tool has heat resistant, resistant 寒, flame retardant and other multiple excellent material features. is PC resistant outer can force very 差. 随 社会 不断 development 进步, market demand improve/increase, for PC requirements 也越 越 high, therefore R&D especially type type PC, ratio flame retardant PC也就 formed 当务之急.
from principle upper 说, flame retardant PC main/primary principle is for PC进行 catalytic, make its in 燃烧 时候 can formed carbon, 以此 达 to flame retardant 效果. flame retardant PC remove tool has good material features outer, also has many excellent chemical features, ratio it oil resistant property and resistant acid property very good, is for strong/high alkali property resistant force generally.
generally 说, flame retardant PC more used for various electronics product and product outer housing/shell, table/sheet 盘, table/sheet sheet/plate and other and other field/area. currently, flame retardant PC tool has multiple system can to flame retardant 效果, is its in has types is 效果, this types use very less agent amount can to very good flame retardant 效果, in many field/area has application. in this heavy to large introduction lower its in catalytic flame retardant system:
catalytic flame retardant system is 一 化 combined material, this combined material in conditions lower can through water formed strong/high acid, this combined material can make PC and other high polymer formed carbon, from to flame retardant 目. 当然, this category of combined material for/regarding type polymer flame retardant 效果并不理想. is, false through catalytic agent catalytic function polyolefin can oxidation hydrogen separation 子 话, that can formed water and carbon, this can large degree improve/increase material flame retardant 效果.
[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
