   ABS is plastics material 里 万 can 王之一, it therefore by use, is is it hard, also can by formed 五颜六 color has gloss. 今天, 我们就 good good understanding ABS.

     in 文名: ABS plastics

    英文名称: AcrylonitrileButadieneStyrene

    专业名称: acrylonitrile-butadiene-styrene (ABS) copolymer

    ABS 自述:

    “我” in chemical formed upper acrylonitrile A, butadiene B and styrene S三 types mono copolymer formed polymer, 简称ABS. types mono tool has different features, from upper 看, ABS is non crystallization property material. this 就决定 “我” tool has low temperature resistance property, impact resistant property, appearance features, low creep property, excellent dimensional stability and easy processing property and other multiple features. surface hardness high, chemical resistance good, meanwhile through upper types separation ratio/proportion, can 改变“我” various property can, 故“我” as is engineering plastics tool has applications. combined formed ABS has in impact type, high impact type, ultra-high impact type and heat resistant type type.

    随 三 types formed separation ratio/proportion adjustment, resin physical properties has 一定 变化: 1,3- butadiene is can is “我” provide low temperature property and impact resistant property, is more butadiene reduce resin hardness, gloss and flow property; acrylonitrile is “我” provide hardness, heat resistant property, resistant acid alkali salt and other chemical property 质; styrene can is “我” provide hardness, processing flow property and product surface light degree.

    ABS basic property 质

    ABS raw materials is shallow ** or white material, has tough property, density is 1.04~1.06g/cm3. it resistant acid, alkali, salt can force comparison strong/high, can in 一定程 degree upper resistant has machine solvent agent solvent understanding.

    ABS resin can in -25℃~60℃ ring lower performance positive 常, but also has very good molding property, processing product surface light 洁, easy color and electroplating. therefore it can by used for home appliances outer housing/shell, toys and other day commonly used product. Common high 积木就 is ABS products.

    ABS resin can and multiple resin mixed formed blending material, 如PC/ABS, ABS/PVC, PA/ABS, PBT/ABS and other, generate new property can and new application areas, 如: will ABS resin and PMMA mixed combined, can manufacturing transparent ABS resin.

    ABS property can

    01, generally property can

    ABS appearance is transparent 呈象牙 color material, 无毒, 无味, water absorption low its products can formed various color, tool has 90% high gloss degree. ABS versus for density is 1.05, ABS同 its it material combined property good, easy surface printing, coating and plating 处理. ABS oxygen index (LOI) is 18.2, easy polymer, 火焰呈黄 color, has 黑烟, 烧焦但不滴落, 并发出特殊 肉桂味.

    ABS is types comprehensive property can separation good resin, in comparison wide temperature degree scope/range inner tool has relatively high impact strong/high degree and surface hardness, heat deflection temperature (HDT) ratio PA, PVC high, dimensional stability good, shrinkage rate in 0.4%～0.8% scope/range inner, glass fiber reinforced rear can decrease/reduce to 0.2%～0.4%, but also less 出现塑 rear shrinkage. its surface force is 34—38mN/cm.

    ABS melt flow property ratio PVC and PC good, ratio PE, PA and PS差, and POM and HIPS similar. ABS flow features non 牛顿流体, its melt viscosity and processing temperature degree and speed rate has 关系, for speed rate more is 敏感.

    02, force property can

ABS has excellent force property can, its impact strong/high degree good, can in low temperature degree lower use. make ABS products by bad, can is tensile bad 而不会 is impact bad. ABS wear resistance can excellent 良, dimensional stability good, also tool has oil resistant property, can used for in and other and speed lower bearings. ABS creep property ratio PSF and PC large, ratio PA and POM small. ABS flexural strength and pressure shrink strong/high degree plastics in relatively 差. ABS force property can temperature degree effect/influence relatively large.

    03, hot property can

    ABS belongs to 无定形 polymer, obvious melting point; melt viscosity relatively high, flow property 差, weather resistance relatively 差, outer can make color; heat deflection temperature (HDT) is 70—107℃(85 left right), products 经退火处理 rear also can improve/increase 10℃ left right. for temperature degree, speed rate comparison 敏感;ABS in -40℃时 still can performance 出一定 tough property, can in -40℃ to 85℃ temperature degree scope/range inner long use. hot separation understanding temperature degree 270 above.

    04, electrical property can

    ABS electrical insulation property relatively good, and 几乎不受 temperature degree, wet degree and frequency rate effect/influence, can in large more ring lower use.

    05, ring property can

    ABS不受 water, machine salt, alkali alcohol type and type solvent agent and multiple acid effect/influence, can solvent ketone type, aldehyde type and chlorine 代烃, 受冰乙 acid, material and other 侵蚀会 generate force cracking. ABS weather resistance 差, in outer function lower easy generate degradation, 置于户 outer semi year rear, impact strong/high degree decline semi.

    ABS application

ABS拥 has comprehensive property can (impact resistant property, high rigidity, oil resistant property, low temperature resistance property, chemical resistant property and electrical properties and processing easy property, price low property), is this world can or 缺 组 separation, therefore in electronics electrical appliances, device table/sheet, automotive, construction industrial and other field/area 无 不 in.
