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 reinforced resin composition may include a polycarbonate, a functionalizing agent, and an inorganic filler that has been functionalized with the functionalizing agent, the functionalized inorganic filler being present in an amount ranging from 1 to 25 percent by weight of the resin composition. The reinforced resin may exhibit a melt flow index of 25 or less, when measured at a load of 1.2 kg, after allowing the resin to remain at a temperature of 300° C. for 10 minutes. A method of reducing thermal degradation of a reinforced polycarbonate material may include introducing into said polycarbonate material at least one inorganic filler functionalized with a functionalizing agent, such that the reinforced resin exhibits a melt flow index of 25 or less, when measured at a load of 1.2 kg, after allowing the resin to remain at a temperature of 300° C. for 10 minutes.

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.
