A composition and a method for preparing a polymer composite article. The composition comprises (A) a filler in an amount of from 10 to 90 wt. The composition also comprises (B) a polymer in an amount of from 10 to 90 wt %, wherein the (B) polymer is selected from polyolefins, polyamides, polyesters, or combinations thereof. Further, the composition comprises (C) an organopolysiloxane in an amount of from greater than 0 to 10 wt. %; the (C) organopolysiloxane having at least one silicon-bonded hydroxyl group and a viscosity of from 1,000 to 60,000 mPa·s at 25° C. The ranges for components (A)-(C) are based on the total weight of components (A), (B) and (C) in the composition.
