Ke kahe kiʻekiʻe ABS-GF, FR kiʻekiʻe wela pale no ka OA noi

ʻO ABS kahi terpolymer i hana ʻia e ka polymerizing styrene a me ka acrylonitrile i mua o ka polybutadiene. Hiki ke ʻokoʻa nā ʻāpana mai 15% a 35% acrylonitrile, 5% a 30% butadiene a me 40% a 60% styrene. ʻO ka hopena, he kaulahao lōʻihi o ka polybutadiene crises-crossed me nā kaulahao pōkole o ka poly(styrene-co-acrylonitrile). ʻO nā pūʻulu nitrile mai nā kaulahao pili, he polar, huki kekahi i kekahi a hoʻopaʻa pū i nā kaulahao, e ʻoi aku ka ikaika o ABS ma mua o ka polystyrene maʻemaʻe. Hāʻawi pū ka acrylonitrile i ke kūpaʻa kemika, ka pale ʻana i ka luhi, ka paʻakikī, a me ka rigidity, ʻoiai e hoʻonui ana i ka wela deflection wela. Hāʻawi ka styrene i ka plastic i kahi ʻālohilohi, impervious ʻili, a me ka paʻakikī, rigidity, a me ka maʻalahi o ka hana ʻana. ʻO ka polybutadiene, kahi mea rubbery, hāʻawi i ka paʻakikī a me ka ductility i nā haʻahaʻa haʻahaʻa, ma ke kumu kūʻai o ka pale wela a me ka rigidity. No ka hapa nui o nā noi, hiki ke hoʻohana ʻia ka ABS ma waena o -20 a me 80 °C (−4 a me 176 °F), no ka mea, ʻokoʻa kona ʻano mechanical me ka mahana. Hoʻokumu ʻia nā waiwai e ka paʻakikī paʻakikī, kahi e māhele ʻia ai nā ʻāpana maikaʻi o ka elastomer a puni ka matrix paʻa.
