休斯顿2014年4月24日电 /美通社/ -- 全球领先的苯乙烯嵌段共聚物 (SBC) 以及其它工程聚合物的创新者与生产商科腾高性能聚合物公司 (KratonPerformance Polymers, Inc.) (NYSE: KRA) 今天宣布，该公司推出两款全新氢化苯乙烯嵌段共聚物(HSBC)。Kraton™ MD6951 和 Kraton™ MD1648 代表了在极强弹性、超高拉伸强度和突出的低熔粘度方面的独特平衡，这将支持可待探索的一系列全新工艺应用。这两种聚合物均为 HSBC 多功能产品系列 KratonA 和增强型塑料粘合剂(ERS) 聚合物的拓展，并将使创新者能寻求熔喷、注射模塑、旋转模塑、压缩模塑或纺织工艺，同时保持其产品的柔软度、强度和柔韧性。
Kraton™ MD6951
美国科腾推出SEBS ：Kraton™ MD6951 和 Kraton™ MD1648
MD6951 是 Kraton A 产品系列最新的 HSBC，具备市面上前所未有的增强型通流能力。它具有多种潜在用途，包括模塑上面的柔软质感，这可以生产手机保护膜与电工工具把套、保护性薄膜和良好的阻尼材料等产品。MD6951 保持了 Kraton A 产品系列的稳定性和特征，例如柔软性、轻松使用和兼容性。此外，它增强的极性使其能与热塑性聚氨酯、聚苯乙烯和聚氧二甲苯等产品兼容。MD6951 通过美国食品及药物管理局 (FDA) 认证，具备突出的弹性并使日常用品更加耐用、更有弹性和更加舒适，这为产品创新者提升了价值，同时拓展了工艺应用技术。
Kraton™ MD1648
MD1648 是一款 ERS 苯乙烯嵌段共聚物。ERS 聚合物可与聚烯烃兼容，例如聚丙烯和聚乙烯等塑料可用作手术和保护性服装、尿布和工业用纺织品具有弹性的非织物。历来而言，SBC 具有一定的限制，因为高粘度使其不适合良好的纤维加工。然而，由于 MD1648 具备极强弹性和强度，以及突出的低粘度，所以它能用于现有的熔喷加工设备中。这为制造商开发更具弹性、更加柔软的产品打开了一扇大门，还能使纺织工艺更加安静。此外，MD1648 还可用于提升聚丙烯改良型家用产品，汽车零件，胶带、喷胶和气雾剂粘合剂等热熔胶和工业材料。
科腾技术部副总裁Lothar Freund 表示：“这两款技术进步产品对我们客户和聚合物行业未来产生的意义令我们振奋。MD6951 和 MD1648 支持多个不同行业探索全新市场并寻求前所未有的全新工艺应用。我们很高兴缩短了这种差距，从而使全球创新者能开发可以改善日常生活的全新和更好产品。”

Kraton Performance Polymers, Inc.(NYSE:KRA), a leading global innovator and producer of Styrenic Block Copolymers(SBCs) and other engineered polymers, today announced the introduction of twonew hydrogenated styrenic block copolymers (HSBCs). Kraton™ MD6951 and MD1648present a unique balance of high elasticity, extraordinary tensile strength andexceptional lower melt viscosity（高弹性，优异的拉伸性能以及超低的熔体粘度）, which will allow for a host of new process applications to beexplored. Both polymers are an extension of the versatile family of HSBCs -Kraton A and ERS polymers - and will enable innovators to pursue melt blown,injection molding, rotational molding, compression molding, or textileprocesses（以上两款均适用于吹膜，注塑，旋转模塑，压缩成型，以及无纺布生产，同时保持很好的柔韧性，强度，弯曲度）, while maintaining the softness, strength, and pliability of theirproducts.
Kraton™ MD6951
MD6951 is the newestHSBCin the Kraton Afamily (属于kraton A系列产品）, and has an enhanced flowcapability （前所未有的高流动性）neverbefore seen on the market. It has several potential applications, includingsoft touch over molding, which produces such products as cell phone protectorsand power tool grips, protective cling films and sound dampening materials.MD6951 maintains the reliability and hallmarks of the Kraton A family, such assoftness, ease of use and compatibility. Additionally, its increased polaritymakes it compatible with thermoplastic polyurethane, polystyrene, polyphenyleneoxide, among others（同TPU，PS，PPO，相容性很好，岳化的YH-511应该也是一样的目的）.MD6951 isFDA-compliant, possesses exceptional elasticity, and makes everydayproducts more durable, resilient and comfortable - adding value for productinnovators, while expanding process application techniques.
Kraton™ MD1648
MD1648 is an enhanced rubber segment (ERS，增强橡胶段) styrenic block copolymer.ERS polymers are compatible with polyolefins such as polypropylene andpolyethylene - plastics used in such materials as elastic non-wovens forapplications such as surgical and protective apparel, diapers and industrialtextiles（可用作无纺布，手术衣等）.
Historically, SBCs had certain limitationsbecause of high viscosity making them unsuitable for fine fiber processing.However, because MD1648 possesses high elasticity and strength togetherwithexceptionally low viscosity, it can run on existing melt blown processequipment（超高熔指，超低粘度可以 进行吹塑）. This opens the door formanufacturers to create products that are more flexible, softer and can producequieter fabric constructions. In addition, MD1648 may be leveraged to improvepolypropylene modified household goods, automotive parts, hot melt adhesiveslike bonding tapes, spray and aerosol adhesives, and insulating materials.
According toLothar Freund, Vice Presidentof Technology at Kraton, "We are excited about what these two technicaladvances mean for our customers and the future of the polymer industry. MD6951and MD1648 allow many different industries to explore new markets and uncovernew process applications that were never before available. We are proud tobridge this gap that will allow innovators across the globe to produce new andbetter products that will enhance our everyday lives."
