ASA/PC structure and features

ASA/PC is polycarbonate (PC) PC and acrylic ester - styrene -丙腈 terpolymer ASA alloy , is types new type polymer alloy , 系由西德BASF company manufacturing , its property similar 于ABS. 但ASA UV resistant and resistant property good , meanwhile tool has good gloss, tough property and rigid property , resistant hot, anti-static and chemical resistance can very excellent. ASA in has C=C di 键, tool has relatively high 玻璃化转变 temperature degree , 但 low temperature impact resistant property and ABS low negative conditions lower , add 入PC rear alloy high temperature deformation property non small , for resistant impact strong/high degree improvement non large .

ASA/PC property can

ASA/PC is for ABS weather resistance disadvantages development engineering plastics. it comprehensive acrylic ester has resistant impact property, weather resistance, machine material property, acrylic chemical resistant product has property, high hardness, styrene excellent and processing property is is 一体, mechanical properties good, weather resistance excellent, especially is in suitable for in coating in outer use. widely used in automotive electronics machine electrical day use product outer decoration field/area. ASA/PC alloy bending comparison strong/high degree, flexural modulus, tensile strength and PC versus 当, thin impact strong/high degree high 于ASA, and PC versus 当. in thick products force cracking, low temperature impact, 缺口敏感 property excellent 于PC, in impact resistant strong/high degree 方面显示出良 good 协同效应, especially combined made as structure products.

ASA/PC processing molding

ASA/PC in molding processing product 时, effect/influence quality lower method make hot amount accelerated through plastics, can methods achieve short cooling time ensure cooling system can will hot amount 以 需 speed degree from mold belt/tape 走; can 行, that cooling system 本身就变 formed hot amount bottle 颈, cycle very long. if short cooling time, that 么模塑 parts thin, cooling system efficiency need high. can achieve short cooling time causes is is parts complex, very difficult cooling 通道; its it causes can can is and design cooling system versus 匹配, or in cooling 通道集结 腐蚀 material and water 垢. is anti 止扭曲 deformation, parts must cooling 并变 足够坚 hard rear can from mold in 脱出. 当顶杆不 again property deformation or can 接受应 force 时, to time requirements. in demolding process in 发生 任何应 force or deformation will 取决于部 parts 几何形状, ejection methods, shrinkage rate and parts and mold between abrasion scratch.  ASA/PC processing 时必需 for material system （ gate / runner ） 凝 solid time and demolding time balanced. if material system solid fast, that 么就没 has holding pressure, this 会导致部 parts quality 欠佳. versus for 而言, if in parts demolding front, material system solid need very long time, that 么就造 formed production time upper 浪费. therefore, material system dimensions and parts cooling time versus 匹配. is runner dimensions and thick ratio rate, use this ratio rate same cooling time, cooling time 方程做 formed and other 式.

ASA/PC application

ASA/PC tool has excellent resistant 寒, high heat resistant property. ASA/PC weather resistance good , recommendation used for automotive upper external application , 如 automotive rear 视镜, dispersion hot device 格栅, 尾部档 sheet/plate, lamp covers and other day and 雨淋, strong/high and other poor conditions lower external parts; ASA/PC also used for 摩托车面 sheet/plate, automotive, small type housing/shell, sheet/plate, 园艺灌溉 equipment, 草坪切割 machine outer housing/shell, resistant use equipment outer housing/shell, 如: machine, electrical machine, equipment, 卫星天线 and other full housing/shell and other and other. industrial production in ASA/PC广泛 used for manufacturing bearings, gears, 凸轮, gears, various 滚子, slip 轮, 泵叶轮, 风扇叶 sheet/slice, 蜗轮, device, 螺钉, 螺母, sheet/slice, high pressure 密封圈, oil resistant 密封垫 sheet/slice, oil resistant container, outer housing/shell, soft tube/pipe, cable jacket, machine slip sleeve/set, 牛头刨床 slip block electrical magnetic separation base/seat, cold equipment, 衬垫, bearings maintain 架, automotive and machine upper various tube/pipe, active 塞, 绳索, 传动皮 belt/tape, textile machine industrial equipment material, and day use product and packaging film and other. ASA/PC in automotive field/area large is manufacturing table/sheet 盘, its manufacturing sheet/plate, 轮罩, machine, 尾部排 gas 格栅, battery and other. in electronics electrical field/area used for manufacturing office equipment, 笔记本 electrical 脑, printing machine and true machine outer housing/shell, electrical machine housing/shell, machine housing/shell, CD-ROM驱动盘, connectors, 通讯工 tool and other.
