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.
