        一, ASA and ABS材 material structure

        1)ASA(acrylonitrile-styrene-acrylate terpolymer) engineering plastics is acrylic ester type 橡胶体 and acrylonitrile, styrene grafting copolymer.

        2)ABS plastics, is acrylonitrile A, butadiene B and styrene S copolymer polymer/macromolecule material,

        二, ABS and ASA comparison

        1.ABS advantages and disadvantages

         advantages:

        ABS has excellent comprehensive property can, good impact strong/high degree, has relatively good low temperature property can, in low temperature lower strong/high degree decline more.

         wear resistance: ABS wear resistance can very good, can lubricated material, is due to good dimensional stability, can as in and other negative bearings.

         resistant creep property: product types different 而异, ultra-high 冲ABS products can 承受7Mpa negative dimensions 不变化.

         disadvantages:

         heat deflection temperature (HDT) relatively low, heat resistant grade ABS can 达115℃, temperature degree -7 ℃.

         can 燃, generally grade ABS grade is HB;但经 modified to flame retardant.

         weather resistance relatively 差, through modified or more 换组份 in butadiene can improvement.

        2.ASA property can advantages

        ASA resin is acrylic ester type 橡胶体 and acrylonitrile, styrene grafting copolymer, and ABS versus ratio, due to 引入不含 di acrylic ester 橡胶取代 butadiene 橡胶, weather resistance has essence 改变, ratio ABS high 出10倍 left right;而 other force property can, processing properties, electrical insulation property, chemical resistant property and ABS versus 似.

         use ASA resin processing products, use coating 装, electroplating and other surface anti 护, can in outer use, in day light lower 暴晒9~15 month, impact strong/high degree and elongation 几乎没 has decline, color 也几乎没 has 变化.

        三, ABS and ASA classification and application scope

        (一)ABS classification and application

        ABS excellent comprehensive property can application 广泛, generally grade ABS disadvantages made in industry application; is development very more modified 特殊ABS:

        按 applications can 特殊ABS main/primary separation is flame retardant ABS, transparent ABS, heat resistant ABS and impact resistant ABS.

        1. transparent ABS

         is types and MMA grafting modified ABS, tool has good comprehensive property can, can widely used in electronics, electrical appliances parts, transparent degree 接近亚克 force (PMMA) and polycarbonate (PC) (PC), 且悬臂梁 impact strong/high degree and impact strong/high degree and general purpose ABS versus 似, low impact lower easy cracking.

         main applications product:

        键盘按键, electrical 脑箱体, printing machine cover/cap, 鼠标, printing machine or true machine 纸张支架, 噪声挡 sheet/plate, cationic 蓬, product bottle, 人造指甲.

        2. flame retardant ABS

         is types flame retardant modified 特殊ABS, tool has excellent flame retardant property can, can 广泛 应 used for electrical appliances product outer housing/shell.

         main applications product:

         dry device outer housing/shell, electrical appliances, light printing machine outer housing/shell, electrical 视接收 machine, machine, ATM自动提款 machine, magnetic 卡刷卡 machine, PDP electrical front sheet/plate.

        3. heat resistant ABS

         is types heat resistant agent modified 特殊ABS, tool has excellent resistant thermal properties, in automotive parts, home appliances parts and other industry has application.

         below/following is heat resistant ABS in automotive and use electrical appliances application product:

         electrical 风扇, machine, dry machine, machine, printing machine, 音响, electrical appliances, 导航仪, machine, 手柄, remove machine, electrical table/sheet 箱, water 壶, machine, for machine, device.

        (二)ASA classification and application

        按 applications can ASA main/primary separation is injection molding grade 别, extrusion grade and heat resistant grade 别.

        ASA and ABS structure features separation versus 似, in structure upper ABS butadiene separation by acrylic substitute/replace, is ASA.

        ASA不含 has di 键, therefore can in long 期苛刻 户 outer conditions lower maintain color and property can stability property. in addition versus ratio polypropylene (PP) type polymer more excellent resistant scratch property.

        1. ASA因 its excellent force property can, good color property, excellent weather resistance, good processing property and ratio PVC more good resistant heat stabilized property, make ASA广泛 应 used for extrusion type industry.

        2. ASA also can used for automotive industry, manufacturing rear outer housing/shell, 通风格栅 and other automotive parts, in 现代, general purpose, and other automotive enterprise, already has more formed 功案例. main applications product: rear outer housing/shell and 支架, 通风隔栅, dispersion hot device 格栅.

        四, summary

         due to ASA resin structure and formed, ASA ratio ABS tool has more good impact resistant property, weather resistance and high temperature resistance property, in construction and bathroom fixtures, automotive and 摩托车, electronics electrical engineering, outer equipment and device and other field/area tool has application. utilizing 安庆石化 styrene, acrylonitrile research and development ASA resin, tool has more vast development outlook/prospects.
