SBS mutatio BSPLT utitur basi bitumen sicut rudis materia, adiungit quaedam ratio SBS Modifier, et utitur tonderet, concursum et alii modi ad aequaliter dispersi in bitumine. Simul proportio proportio stabilitorque additur formare SBs mixtio. Material, usura bonum physica proprietatibus SBS ad mutare bituminis.
Usus modifiers ad mutari bitumen habet diu historia internationally. In medium-19th century, in Vulcanization modum erat usus ad redigendum penetrationem bitumen et crescere mollitie punctum. In progressionem mutatio in praeteritum L annis est roughly abiit per quattuor gradus.

(I) 1950-1960, directe misce purgamentum pulveris vel lateex in bituminis, miscere aequaliter et usu;
(II) ex MCMLX ad MCMLXX, styerene-butadiene syntheticum Flexilis erat mixta et usus est in-site in forma LATEX in proportione;
(III) ex MCMLXXI ad MCMLXXXVIII, praeter continua applicationem de Saccharum Flexilis, thermoplastic resins sunt late usus;
(IV) Cum MCMLXXXVIII, SBs paulatim facti sunt ducit immutabile materia.
A brevis historia de progressionem SBS mutatio Modified:
★ mundi industriae productio SBS products coepit in 1960s.
★ In MCMLXIII, in American PETROLEUM Company solebat in modum ad producendum linearibus SBS copolymer ad primum tempus, cum commercia nomen solprene.
★ MCMLXV in American testa turba usus negative Ion polymerization technology et tres-gradus sequentem pascere modum ut develop a similis uber et consequi industriae productio, cum commercia nomen Kraton D.
★ In MCMLXVII, in Batavica Company Philips Developed a stella (vel radiale) SBS uber.
★ In MCMLXXIII, Philips ad launched stella SBS uber.
★ MCMLXXX, Firestone Company launched an SBS uber nominatur Streon. Quod productum est styerene binding contentus erat XLIII%. Quod productum habebat alta liquescit index et maxime propter plastic modificatio et calidum adorat adhaesives. Deinde, Japan scriptor Asahi Kasei Company, Italy Anic Company, Belgium Petrochim Company, etc. Etiam successive developed SBs products.
★ Post intrantes 1990s, cum continua expansion SBS applicationem agros, mundi SBS productio habet developed cursim.
★Since 1990, when the synthetic rubber plant of Baling Petrochemical Company in Yueyang, Hunan Province built the country's first SBS production device with an annual output of 10,000 tons using the technology of Beijing Yanshan Petrochemical Company Research Institute, China's SBS production capacity has grown steadily.
