    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.

    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 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 0.6. 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: A deaerated talc may include micronized, talc powder having a Hegman rating of 4.0 or greater. A deaerated talc may include micronized talc powder having enough cohesive strength for form agglomerations measuring 100 millimeters or less, 75 millimeters or less, or 50 millimeters or less. A deaerated talc product may include a micronized talc powder, and a bag containing the deaerated talc. The micronized talc powder may be deaerated via application of force to the micronized talc powder in at least two directions, including a first direction substantially parallel to the longitudinal direction of the bag and a second direction.
