休斯頓2014年4月24日電 /美通社/ -- 全球領先的苯乙烯嵌段共聚物 (SBC) 以及其它工程聚合物的創新者與生產商科騰高性能聚合物公司 (KratonPerformance Polymers, Inc.) (NYSE: KRA) 今天宣布，該公司推出兩款全新氫化苯乙烯嵌段共聚物(HSBC)。Kraton? MD6951 和 Kraton? MD1648 代表了在極強彈性、超高拉伸強度和突出的低熔粘度方面的獨特平衡，這將支持可待探索的一系列全新工藝應用。這兩種聚合物均為 HSBC 多功能產品系列 KratonA 和增強型塑料粘合劑(ERS) 聚合物的拓展，并將使創新者能尋求熔噴、注射模塑、旋轉模塑、壓縮模塑或紡織工藝，同時保持其產品的柔軟度、強度和柔韌性。

MD6951 是 Kraton A 產品系列最新的 HSBC，具備市面上前所未有的增強型通流能力。它具有多種潛在用途，包括模塑上面的柔軟質感，這可以生產手機保護膜與電工工具把套、保護性薄膜和良好的阻尼材料等產品。MD6951 保持了 Kraton A 產品系列的穩定性和特征，例如柔軟性、輕松使用和兼容性。此外，它增強的極性使其能與熱塑性聚氨酯、聚苯乙烯和聚氧二甲苯等產品兼容。MD6951 通過美國食品及藥物管理局 (FDA) 認證，具備突出的彈性并使日常用品更加耐用、更有彈性和更加舒適，這為產品創新者提升了價值，同時拓展了工藝應用技術。

MD1648 是一款 ERS 苯乙烯嵌段共聚物。ERS 聚合物可與聚烯烴兼容，例如聚丙烯和聚乙烯等塑料可用作手術和保護性服裝、尿布和工業用紡織品具有彈性的非織物。歷來而言，SBC 具有一定的限制，因為高粘度使其不適合良好的纖維加工。然而，由于 MD1648 具備極強彈性和強度，以及突出的低粘度，所以它能用于現有的熔噴加工設備中。這為制造商開發更具彈性、更加柔軟的產品打開了一扇大門，還能使紡織工藝更加安靜。此外，MD1648 還可用于提升聚丙烯改良型家用產品，汽車零件，膠帶、噴膠和氣霧劑粘合劑等熱熔膠和工業材料。

科騰技術部副總裁Lothar Freund 表示：“這兩款技術進步產品對我們客戶和聚合物行業未來產生的意義令我們振奮。MD6951 和 MD1648 支持多個不同行業探索全新市場并尋求前所未有的全新工藝應用。我們很高興縮短了這種差距，從而使全球創新者能開發可以改善日常生活的全新和更好產品。”

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（高彈性，優異的拉伸性能以及超低的熔體粘度）, 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（以上兩款均適用于吹膜，注塑，旋轉模塑，壓縮成型，以及無紡布生產，同時保持很好的柔韌性，強度，彎曲度）, while maintaining the softness, strength, and pliability of theirproducts.

Kraton? MD6951

MD6951 is the newestHSBCin the Kraton Afamily (屬于kraton A系列產品）, and has an enhanced flowcapability （前所未有的高流動性）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應該也是一樣的目的）.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，增強橡膠段) 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（可用作無紡布，手術衣等）.

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 進行吹塑）. 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."
