about/regarding PC/ABS配 ratio, 我们耳熟 can ratio/proportion is 70/30. that is what is this ratio/proportion 呢? it in what lower is most excellent selection 吗?

will ABS38(Rubber=38%) and combined 适SAN blending make content is 16% again and PC3.2（Mw=3.2w）以不 year-on-year blending made alloy, its impact property can lower 图.

can to, PC content improves, PC/ABS 1/8”缺口 impact is increase large, 而1/4”缺口 impact 则呈现先 increase large rear decrease small trend, in PC/ABS is 70/30时呈现 most large value, is 说此时PC/ABS for thick degree property most low. PC content for PC/ABS脆 tough temperature degree effect/influence also is what 样 呢?

upper table/sheet 明, PC/ABS 3.18mm样 strip/profile tough temperature degree basic 随PC content increase large reduce, 而6.35mm样 strip/profile 则呈现先 reduce rear rise high, in PC/ABS is 50/50时呈现 most low value. can 见, for has low temperature tough property requirements PC/ABS 说, 70/30未必 is most selection, but also thick degree meanwhile, its PC content direction different.

can 见, PC in 引入ABS rear, its 3.18mm normal temperature IZOD impact decline, tough temperature degree improves; 但6.35mm IZOD impact strong/high degree improves, tough temperature degree decline. therefore, commonly used ratio 70/30 can is is comprehensive thick degree, temperature degree and other factors for impact property can effect/influence selection.

也 has research is, 当PC/ABS配 ratio is 80/20 时, impact strong/high degree most large value, 当PC/ABS配 ratio is 70/30时, tensile strength 出现极 large value; 当ABS content is 50%时, PC/ABS flow property most good. will market upper commonly used PC1100 and ABS8391复配 rear 发现, basic combined 此规律, lower 图 示.

PC content for PC1100/ABS8391 different thick degree strip/profile notched impact strength effect/influence

therefore, PC/ABS blending material impact strong/high degree performance is and strip/profile thick degree, testing temperature degree and other related, its trend 未必一致, for/regarding different PC and ABS, its most ratio can can has different. from research and experience 看, generally most value in PC content is 60%-80% between. （ above separation data 源于D.R.Paul 论文）
