    Abstract: A composition for fused filament fabrication may include polylactic acid resin and talc. The composition may range from 50% by weight to 99% by weight polylactic acid resin, and from 7% by weight to 40% by weight talc. The composition may be configured as filaments or pellets adapted to be used in a fused filament fabrication process. A method for generating a resin-based structure may include providing a resin source that may include polylactic acid resin and talc. The resin source may include from 50% by weight to 99% by weight polylactic acid resin, and from 7% by weight to 40% by weight talc. The method may also include heating the resin source to a temperature greater than the melting temperature for semi-crystalline resins or significantly greater than glass transition temperature for amorphous resins, and depositing the heated resin source in a layered manner to form the resin-based structure.

    Abstract: A composition may include a first talc having a morphology index less than or equal to about 0.6 and a second talc having a morphology index greater than or equal to about 0.6. The first talc and the second talc may form a talc composition, and the talc composition may have a content ratio of the first talc to the second talc ranging from about 30:70 by weight to about 80:20 by weight. A polymer composition may include a polymer matrix and a filler composition. The filler composition may include a first talc having a morphology index less than or equal to about 0.8 and a second talc having a morphology index greater than or equal to about 0.8, The filler composition may have a content ratio of the first talc to the second talc ranging from about 30:70 by weight to about 80:20 by weight. The first talc may be a microcrystalline talc. The second talc may be a macrocrystalline talc.

    Abstract: The present invention relates to a process for controlling deposits in a paper making process, more particularly to a process comprising the use of talc for controlling deposits in a paper making process with talc. One aspect of the invention is contacting talc with a white water stream at one or more locations within the paper making process after separating pulp from a pulp-containing stream and before introducing the re-circulating the white water stream to one or more of a pulper, a thick-stock, a thin-stock, a dilution process, a shower, a storage vessel, a blending process, and a digestor.
