ʻO SBS (styrene-butadiene-styrene) Poly (styrene-butadiene-styrene) a i ʻole SBS, he lāʻau paʻa i hoʻohana ʻia no ka hoʻololi ʻana i ka asphalt, no ka hana ʻana i nā kapu kāmaʻa, nā hehi huila, a me nā wahi ʻē aʻe i mea nui ka paʻa.He ʻano copolymer i kapa ʻia he block copolymer.He ʻekolu ʻāpana kona kaulahao iwi kuamoʻo.ʻO ka mua he kaulahao lōʻihi o ka polystyrene, ʻo ka waena he kaulahao lōʻihi o polybutadiene, a ʻo ka ʻāpana hope kekahi ʻāpana lōʻihi o ka polystyrene.ʻO ka Polystyrene he mea paʻakikī paʻakikī, a hāʻawi kēia iā SBS i kona lōʻihi.ʻO ka polybutadiene ka lāʻau lapaʻau, a hāʻawi kēia iā SBS i kāna mau waiwai e like me ka lāʻau.Eia kekahi, pili pū nā kaulahao polystyrene.Ke hui kekahi pūʻulu styrene o hoʻokahi mole SBS i hoʻokahi puʻupuʻu, a hui pū kekahi kaulahao polystyrene o ka mole SBS hoʻokahi i kekahi puʻupuʻu, ua nakinaki ʻia nā ʻāpana ʻokoʻa me nā kaulahao polybutadiene rubbery.Hāʻawi kēia i ka mea i hiki ke mālama i kona ʻano ma hope o ke kikoo ʻana
