Polymer micronization through extrusion with supercritical fluids

总的目标是试图开发一种从饱和超临界二氧化碳的聚合物熔体中生产超细纤维和粉末的挤出工艺。雌驼龙聚合物作为其主要生产商部门的一部分，提供尺寸缩小服务。作为热塑性塑料研磨领域的领导者，雌驼龙可以生产出满足客户在旋转成型、粉末涂料、混合和分散等应用中所需的全系列粉末。使用专利技术和专有技术精确控制颗粒大小分布和形态，以优化产品性能。该项目将使雌驼龙能够继续探索超临界二氧化碳在挤出/复合操作中的创新使用，目的是为不同的汽车供应商开发一种生产微粉化聚合物化合物和粉末的低能耗工艺。这些微粉化的粉末可以转化为各种工程汽车塑料部件。另一个汽车应用领域是“雪泥”成型领域，这是一种非常类似于旋转成型的过程，需要粉末聚合物。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.
