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: 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.
