Contains <1% diblock copolymer. Medium styrene, high modulus copolymer. Outstanding thermal stability. Supplied as a porous pellet, dusted with talc. VECTOR styrenic block copolymers find use under certain regulations as articles or as ingredients in articles intended for food contact or medical applications. Please contact your Dexco Polymers agent for a detailed letter of certification or further information. VECTOR 2518 styrene-butadiene-styrene block copolymer is produced via proprietary sequential anionic polymerization technology from Dexco Polymers LP, a Dow/ExxonMobil Venture. It has excellent thermoplastic elastomer properties and outstanding physical strength. It is designed for use as an impact/toughness modifier in blends with styrenics and in elastomeric compounds. It is also used as an asphalt modifier to lower temperature susceptibility and in roofing compounds. VECTOR® 2518 Linear SBS triblock copolymer. Contains <1% diblock copolymer. Medium styrene, medium modulus. VECTOR 2518 styrenic block copolymer is a linear triblock copolymer with a narrow molecular weight distribution. It has excellent thermoplastic elastomer properties and outstanding physical strength, making it well-suited for use as a binder in elastomer compounds. It is formulated with the antioxidant tris(nonylphenyl) phosphite (TNPP). VECTOR 2518 SBS is offered as a porous pellet supplied from the United States.	载体2518A VECTOR® 2518A苯乙烯-丁二烯-苯乙烯（SBS）嵌段共聚物SBS（1）三嵌段共聚物。含有<1%的二嵌段共聚物。中苯乙烯，高模量共聚物。卓越的热稳定性。以多孔颗粒形式提供，撒上滑石粉。载体苯乙烯嵌段共聚物可根据某些规定用作食品接触或医疗用品中的物品或成分。请联系您的DEXCO聚合物代理商，以获取详细的证书或进一步的信息。VECTOR® 2518A苯乙烯-丁二烯-苯乙烯嵌段共聚物是由道指/埃克森美孚合资企业Dexco Polymers LP通过专有的连续阴离子聚合技术生产的。VECTOR® 2518A不与抗氧化剂TNPP（三（壬基苯基）亚磷酸酯）一起配制。它比矢量8508A SBS具有更好的抗蠕变性能。它具有优异的热塑性弹性体性能和优异的物理强度。它设计用于与苯乙烯混合物和弹性薄膜化合物的冲击/韧性改性剂。Vector 2518A线性SBS三嵌段共聚物。含有<1%的二嵌段共聚物。中等苯乙烯，中等模量。苯乙烯嵌段共聚物是一种分子量分布窄的线性三嵌段共聚物。它具有优异的热塑性弹性体性能和优异的物理强度，比载体8508a SBS更耐蠕变。它非常适合与苯乙烯类化合物和弹性体化合物的混合物中使用。VECTOR® 2518A SBS是由美国提供的多孔颗粒。 VECTOR® 2518A VECTOR 2518A Styrene-Butadiene-Styrene (SBS) Block Copolymer SBS(1) triblock copolymer.
