  • Patent number: 8980144
    Abstract: The invention relates to a method for producing a biaxially oriented polypropylene film including at least one layer, which is constructed from propylene polymer B and a propylene polymer that has been recycled once. The method includes heat and melting propylene polymer B in a first extruder and heating a melting a propylene polymer A without a fraction of recycled material in a second extruder. The molten mass of the propylene polymer A is fed to two sides of the propylene polymer molten mass of B such that the propylene polymer A forms border regions of the film during the production process. The two border regions are then cut off after longitudinal and traverse stretching of the film, and melted and mixed together with the propylene polymer B and extruded to form a precursor film in the first extruder. The biaxially oriented polypropylene film comprising a propylene polymer that has been recycled only once is useful for producing capacitors.

  • Publication number: 20130216753
    Abstract: Polyester compositions described herein have properties which are particularly suitable for extrusion blow molding (EBM). These properties relate primarily to the rate of crystallization and melt strength or melt viscosity. Articles prepared from the polyester compositions exhibit good clarity, aesthetics, and other physical properties. The polyester compositions also exhibit broad molecular weight distribution (MWD), resulting in improved processability and melt strength. The crystallization rate allows for good drying characteristics while also enabling the use of regrind. In addition, the compositions exhibit improved recyclability, such as in existing PET recycling streams. In one aspect, articles are prepared in an extrusion blow molding method by combining a dry first polyester copolymer component, a dry second polyester component, and a chain extender to form a feed material suitable for extrusion blow molding.

  • Publication number: 20110198768
    Abstract: A method for the manufacture of container preforms in which recycled plastic material is subjected to at least one heat treatment in a recycling machine before it is transferred to a preform machine, where at least a major portion of heat introduced into the plastic material during its heat treatment and storage is transferred from the recycling machine with the plastic material into the preform machine. In a plant embodied for carrying out the method, the recycling machine is coupled with the preform machine either directly or via at least one intermediate storage such that at least a major portion of heat introduced in the recycling machine during a heat treatment of the plastic material can be transferred with the plastic material into the preform machine.

  • Patent number: 7959836
    Abstract: Disclosed is a process for the preparation of shaped articles such as, for example, sheeting, films, tubes, bottles, preforms and profiles, having high transparency and low haze, and comprising immiscible blends of at least one polyester comprising 2,2,4,4-tetramethyl-1,3-cyclobutanediol, and a copolyamide or a transamidized, homogeneous blend of a least two polyamides. The components of the immiscible blend have refractive indices which differ by about 0.006 to about ?0.0006. The small difference in the refractive indices enable the incorporation of regrind into the polymer composition to produce transparent shaped articles. These articles may have one or more layers and can exhibit improved excellent barrier properties and good melt processability while retaining excellent mechanical properties. Metal catalysts can be incorporated into the compositions to produce shaped articles having oxygen-scavenging properties.

  • Publication number: 20110121475
    Abstract: An apparatus and method for manufacturing a down hole tool that reduces manufacturing costs and enhances the tool's performance. A belted mold assembly includes a casting assembly, a belt assembly, and a mid-belt. The belted mold assembly is used to fabricate a casting that allows for a larger diameter blank to be used which displaces the more expensive casting material and for using a smaller outer diameter thin-walled mold. The casting assembly is disposed within the belt assembly and the mid-belt is loaded in the volume created between the casting assembly's outer surface and the belt assembly's inner surface. The mid-belt provides a bracing for the casting assembly during the casting process. Optionally, a cap can be disposed on top of the blank for preventing metallurgical bonds from forming between the binder material and the upper portion of the blank. This allows for the excess binder material to remain high in purity so that it can be reprocessed.
