| Eastman很高兴宣布推出Drystar*共聚酯。该新产品线是为满足变换器对共聚酯干燥要求寻求增值解决方案的需要而设计的。伊士曼？S共聚酯因其优异的美学、冲击强度和耐化学性等性能平衡而受到高度重视。当树脂按照推荐的干燥条件和设备适当脱水时，这些性能可以得到最佳的实现。认识到这一价值，Eastman构想了Drystar共聚酯，允许转换器有限地访问干燥剂烘干机，以实现这些优化。此外，一些带有干燥剂烘干机的转换器可能仍然发现Drystar共聚酯的价值增加，通过在注塑、型材挤压或挤出吹塑共聚酯之前去除干燥过程，从而获得生产灵活性和成本节约。最初的发布包括四个等级的Drystar共聚酯的商业化，Eastman正在进行计划，以在未来扩展这一战略产品线。*Drystar仅在亚太地区提供。 Eastman is pleased to announce the launch of DRYSTAR* copolyesters. This new product-line is designed to meet the needs of converters seeking value-added solutions to their drying requirements of copolyesters. Eastman?s copolyesters are highly valued for their excellent balance of properties such as superior aesthetics, impact strength, and chemical resistance. These properties can be optimally realized when the resins are properly dehydrated in accordance to recommended drying conditions and equipment. Recognizing this value, Eastman conceived Drystar™ copolyesters to allow converters with limited access to desiccant dryers to achieve these optimizations. In addition, some converters with desiccant dryers may still find Drystar™ copolyesters value-adding to attain production flexibility and cost saving by removing the drying process prior to injection molding, profile extruding, or extrusion blow molding copolyesters. The initial launch comprises of the commercialization of four grades of Drystar™ copolyesters and Eastman has on-going program to extend this strategic product-line in the future. *DRYSTAR is only available in the Asia Pacific Region. |
