Abstract: This disclosure describes processes for producing polymer foams, and compositions of matter relating to these processes. A process includes the steps of dispersing an organic nucleating agent in a dispersing medium to obtain an additive dispersion, contacting the additive dispersion with a mineral nucleating agent to obtain a hybrid nucleating agent containing the organic nucleating agent localized on at least a portion of a surface of the mineral nucleating agent, and contacting the hybrid nucleating agent with a polymer in the presence of a foaming agent to obtain a polymer foam. A foamed polymer of the present disclosure includes a cellular matrix containing a polymer material, and a mineral matrix of particles containing a hybrid nucleating agent dispersed in the cellular matrix, in which the hybrid nucleating agent contains an organic nucleating agent localized on at least a portion of a surface of an inorganic material.

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: 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 recirculating 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.
