Polymer micronization through extrusion with supercritical fluids

总体目标是尝试开发一种用于从用超临界二氧化碳饱和的聚合物熔体生产非常细的纤维和粉末的挤出方法。Ingenia Polymers作为其初级生产部门的一部分提供尺寸缩小服务。作为热塑性塑料研磨领域的领导者，Ingenia可以生产客户在滚塑、粉末涂料、复合和分散等应用中所需的全系列粉末。使用专有技术和专有技术精确控制粒度分布和形态，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/复合操作中的创新用途，以开发一种低能耗工艺，为各种分层汽车供应商生产微粉化聚合物和粉末。这些微粉化粉末可以转化为各种工程汽车塑料部件。另一种汽车应用是在“搪塑”成型领域，这是一种非常类似于旋转成型的工艺，需要粉末状聚合物。正在开发的技术将允许使用比目前可能的更广泛的聚合物材料。此外，利用该技术生产的纤维材料由于其过滤和吸收特性而可以在汽车领域中找到应用。

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.
