SBS (styrene-butadiene-styrene) Poly (styrene-butadiene-styrene) kana SBS, irabha yakaoma inoshandiswa kushandura asphalt, kugadzira sosi dzeshangu, kutsika matayi, nedzimwe nzvimbo uko kusimba kwakakosha.Imhando yecopolymer inonzi block copolymer.Cheni yemusana wayo inoumbwa nezvikamu zvitatu.Yokutanga iketani refu ye polystyrene, yepakati iketani refu ye polybutadiene, uye chikamu chekupedzisira chimwe chikamu chakareba chepolystyrene.Polystyrene ipurasitiki yakaoma yakaoma, uye izvi zvinopa SBS kusimba kwayo.Polybutadiene irabha, uye izvi zvinopa SBS yayo-yakafanana nerubha.Mukuwedzera, maketani epolystyrene anowanzobatana.Kana rimwe boka re styrene reimwe SBS morekuru richibatanidza imwe clump, uye imwe polystyrene cheni yeimwe chete SBS molecule ijoinha imwe clump, masumbu akasiyana anosungwa pamwe chete nerubbery polybutadiene cheni.Izvi zvinopa zvinhu kuti zvikwanise kuchengetedza chimiro chayo mushure mekutambanudza
