COMMODITY	產品項目COMMODITY
SBS (Styrene Butadiene Styrene block polymer)	SBS 苯乙烯-丁二烯-苯乙烯嵌段共聚物

GRADE	規格
Injection (injection) grade, foaming grade, adhesive grade, extrusion grade.Relative molecular mass The linear SBS has an average molecular weight of 80,000 to 120,000, and the star SBS has an average molecular weight of 140,000 to 300,000.	注塑(射出)級，發泡級，粘劑級，押出級，相對分子質量線型SBS平均相對分子質量8萬～12萬，星型SBS平均相對分子質量14萬～30萬

APPLICATION/ CHARACTERISTIC	用途/特性
Relative density: 0.92～0.95 Function: It has excellent tensile strength, elasticity and electrical properties, small elastic deformation, good flexion and resilience, and large surface friction. Oxygen-resistant, oxygen-resistant, similar to horizontal and styrene butadiene rubber chains. Breathability. Because the main bond makes SBS resistant to aging, under the oxidizing condition of outdoor air, the other kind will crosslink, which will increase the hardness and viscosity. Rubber Products: The molding method is mainly used in the shoe (sole) industry, and the extrusion method is mainly used in hoses and tapes. Resin modification: Blending a small amount of SBS with polypropylene (PP), polyethylene (PE), and polystyrene (PS) can significantly improve the low-temperature performance and impact strength of the product. Adhesive: As an adhesive, SBS has the characteristics of high solid content, fast drying, and low temperature resistance. Asphalt modifier: As a modifier of construction asphalt and road asphalt, SBS can significantly improve the weather resistance and load resistance of asphalt. SBS can also be used for toys, furniture and sports equipment; as floor materials, car seat cushion materials, and sound insulation materials, and wire and cable sheaths.	相對密度：0.92～0.95 性能：具有優良的拉伸強度、彈性和電性能，永久變形小，屈撓和回彈性好，表面摩擦大。耐臭氧、氧，紫外線照射性能與丁苯橡膠類似。透氣性優異。由於主鏈含有的雙鍵使SBS耐老化較差，在高溫空氣的氧化條件下，丁二烯嵌段會發生交聯，從而使硬度和黏度增加。橡膠製品-模壓方式主要用於製鞋（鞋底）工業, 押出方式主要用於膠管和膠帶。樹脂改性-少量SBS分別與聚丙烯（PP）、聚乙烯（PE）、聚苯乙烯（PS）共混可明顯改善製品的低溫性能和衝擊強度劑。粘合劑-SBS作為粘合劑具有高固體物質含量、快乾、耐低溫的特點。瀝青改性劑-SBS作為建築瀝青和道路瀝青的改性劑可明顯改進瀝青的耐候性和耐負載性能。 BS還可用作玩具、家具和運動設備的主要原料；用作地板材料、汽車座墊材料、地毯底層和隔音材料以及電線和電纜外皮。
