Shanghai Daoqin Plastics Co., Ltd.

 PC polycarbonate (PC) plastics is 几乎无 color 玻璃态 无定形 polymer, has very good optical property. PC polymer/macromolecule amount resin has very high tough property, 悬臂梁 notched impact strength is 600~900J/m, filling grade heat deflection temperature (HDT) large is 130℃, glass fiber reinforcement rear can make this value increase ℃. PC flexural modulus can 达2400MPa above, resin can processing made formed large rigid property products. low 于100℃时, in negative lower creep rate very low. PC hydrolysis resistant property 差, can used for heavy 复经受 high pressure products. PC材 material tool has flame retardant property, wear resistant. resistant oxidation property. polycarbonate (PC) color transparent, heat resistant, impact resistant, flame retardant BI grade, in use temperature degree inner has good mechanical properties. property can polymethyl methacrylate (PMMA) versus ratio, polycarbonate (PC) resistant impact property can good, rate high, processing properties good, need additives tool has UL 94V-0 grade flame retardant property can. is polymethyl methacrylate (PMMA) versus for polycarbonate (PC) price relatively low, can through polymerization methods production large type device parts.
    
    1, main/primary property can
    
    a, mechanical properties: strong/high degree high, fatigue resistance, dimensions stability, creep small (high temperature conditions lower less has 变化);
    
    b, heat resistant aging property: reinforcement rear UL temperature degree 指数达120~140℃(户 outer long aging property very good);
    
    c, resistant solvent agent property: force cracking;
    
    d, for water stability property: water easy separation understanding (high temperature, high wet ring lower use 需谨慎);
    
    e, electrical properties:
    
    (1), insulation property can: excellent 良(潮 wet, high temperature can maintain electrical property can stability, is manufacturing electronics, electrical parts 理想材 material);
    
    (2), electrical 系数: 3.0-3.2;
    
    (3), resistant electrical property: 120s
    
    f, molding processing property: equipment injection molding or 挤塑. due to crystallization speed degree fast, flow property good, mold temperature degree ratio other engineering plastics requirements low. in processing thin made parts 时, 仅需几秒钟, for large parts need 40-60s即 can.
    
    2, polycarbonate (PC) application
    
    PC polycarbonate (PC) application development is toward high composite/compounding, high function, specialized 化, series direction development, already launch light 盘, automotive, office equipment, 箱体, packaging, 医药, lighting, film and other multiple product specialized product grade grade.
    
    optical lighting: used for manufacturing large type lamp covers, anti 护玻璃, optical device left right 目镜筒 and other, also can used for machine upper transparent material.
    
    electronics electrical appliances: polycarbonate (PC) is excellent E(120℃) grade insulation material, used for manufacturing insulation parts, frame 架, tube/pipe base/seat, insulation sleeve/set tube/pipe, electrical machine housing/shell and parts, battery housing/shell and other. can used for made as dimensions degree very high parts, light 盘, electrical 话, electronics machine, frequency machine, electrical 话交换 device, 信号继 electrical appliances and other device 材. polycarbonate (PC) film also by used as electrical container, insulation 皮包, belt/tape, color color magnetic belt/tape and other.
    
    machine equipment: used for manufacturing various gears, strip/profile, 蜗轮, 蜗杆, bearings, 凸轮, 螺栓, 杠杆, 曲轴, 棘轮, can as machine equipment housing/shell 体, cover/cap and frame and other parts.
    
    medical device 材: can as medical applications 杯, 筒, bottle and device 械, product container and device 械, also can used as 人工肾, 人工肺 and other 人工脏 device.
    
    its it 方面: construction upper used as in di sheet/plate, 暖房玻璃 and other; in textile industry used as textile tube/pipe, textile machine and other; day use as bottle, tool, toys, type, LED灯 outer housing/shell and machine outer housing/shell and other.
