Polymer micronization through extrusion with supercritical fluids

总体目标是尝试开发一种挤出工艺，用于从饱和超临界二氧化碳的聚合物熔体中生产非常细的纤维和粉末。Ingenia Polymers提供尺寸减小服务，作为其初级生产部门的一部分。作为热塑性研磨领域的领导者，Ingenia可以生产客户在旋转成型、粉末涂层、复合和分散等应用领域所需的全系列粉末。粒度分布和形态的精确控制使用专有技术和专有知识，以优化产品性能。该项目将使Ingenia Polymers能够继续探索超临界二氧化碳在挤出/复合操作中的创新应用，目的是为各种分层汽车供应商开发一种低能耗工艺，用于生产微细聚合物化合物和粉末。这些微粉可以转化为各种工程汽车塑料部件。另一个汽车应用是在“泥”成型领域，这是一个非常类似于旋转成型的过程，需要粉末聚合物。这项正在开发的技术将允许使用比目前可能的更多种类的聚合物材料。此外，利用该技术生产的纤维材料由于其过滤和吸收性能，可以在汽车领域找到应用。

It is the overall objective to attempt to develop an extrusion process for the production of very fine fibers and powders from polymer melts saturated with supercritical carbon dioxide. Ingenia Polymers provides size reduction services as part of their Primary Producer Division. As leaders in thermoplastic grinding, Ingenia can produce a full range of powders demanded by the customers' applications in roto-molding, powder coating, compounding and dispersions. Particle size distribution and morphology are precisely controlled using proprietary technology and know-how to optimize product performance. This project will enable Ingenia Polymers to continue to explore the innovative use of supercritical carbon dioxide in extrusion/compounding operations for the purpose of developing a low energy process for the production of micronized polymeric compounds and powders for various tiered automotive suppliers. These micronized powders can be converted to a variety of engineered automotive plastics components. Another automotive application is in the area of "slush" molding which is a process very similar to rotational molding which requires powdered polymers. The technology being developed will allow for the use of a wider variety of polymeric materials than what is currently possible. Also, fibrous material produced with this technology can find applications in the automotive area due to their filtering and absorbing properties.
