        1.ABS property can:

        ABS is acrylonitrile, butadiene and styrene types chemical mono combined formed. (每 types mono tool has different features: acrylonitrile has high strength, heat stabilized property and chemical stability property; butadiene tool has tough property, impact resistant features; styrene tool has easy processing, high light degree and high strength.

        三 types mono polymerization generate tool has versus terpolymer, is styrene - acrylonitrile versus, is poly butadiene dispersion versus.) from upper 看, ABS is non crystallization property material, tool has relatively high machine strong/high degree and good “坚, tough, 钢” comprehensive property can. it is type polymer, ABS is types general purpose type engineering plastics, its product types more 样, applications 广泛, 也称“ general purpose plastics ”, (MBS称 is transparent ABS), ABS easy wet, specific gravity is 1.05g/cm3(ratio water heavy), shrinkage rate low (0.60%), dimensions stability, easy molding processing.

        ABS features main/primary 取决于三 types mono ratio rate and versus in separation structure. this can in product design upper tool has very large active property, and generate market upper types different quality ABS材 material. this different quality material provide different features, from in and other to high and other impact resistant property, from low to high light degree and high temperature features and other. ABS材 material tool has ultra- strong/high easy processing property, appearance features, low creep property and excellent dimensional stability and very high impact resistant strong/high degree.

        ABS is shallow color or 珠状不 transparent resin, 无毒, 无味, water absorption low, tool has good comprehensive material mechanical properties, excellent electrical property can, wear resistance, dimensional stability, chemical resistance and surface gloss and other, easy processing molding. disadvantages is weather resistance, heat resistant property 差, easy 燃.

        2.ABS process features

        2.1ABS wet property and wet property relatively large, in molding processing front must 进行充 separation drying and preheating (is 80~90C lower most less drying 2 small 时), will water separation content control in 0.03% below/following.

        2.2ABS resin melt viscosity for temperature degree property relatively low (and its it type resin different). ABS injection temperature degree although ratio PS稍 high, can 像PS that has wide rise temperature scope/range, can use rise temperature method remove low its viscosity, can use increase screw speed or injection pressure method improve/increase its flow property. generally processing temperature degree in 190-235℃ is 宜.

        2.3ABS melt viscosity in and other, ratio PS, HIPS, AS均 relatively high, using/adopting relatively high injection pressure (500~1000bar)啤货.

        2.4ABS material using/adopting in high speed degree and other injection speed degree 啤货效果 relatively good. (remove non complex, thin made parts use relatively high injection speed degree), product water easy generate gas marks.

        2.5ABS molding temperature degree relatively high, its mold temperature generally adjustment in 25-70℃. production relatively large product 时, 定模(front 模) temperature degree generally ratio 动模(rear 模)略 high 5℃ left right is 宜. (mold temperature degree will effect/influence parts light degree, temperature degree relatively low 则导致 light degree relatively low)

        2.6ABS不宜 in high temperature inner time long (应 small 于30 separation 钟), easy separation understanding 发黄.

        3. typical applications scope/range:

         automotive (仪 table/sheet sheet/plate, tool 舱门, cover/cap, light box/case and other), electrical 冰箱, large strong/high degree tool (头发烘 dry machine, device, food processing machine, machine and other), electrical machine housing/shell 体, machine 键盘, use 车辆如 high 尔夫球手推车以 and gas 式雪撬车 and other.
