Abstract: The present invention relates to non-oriented and oriented polyvinyl chloride pipe comprising: a) polyvinyl chloride; b) from 2 to 5 parts by weight of polymeric processing aid per 100 parts by weight of the polyvinyl chloride; and c) from 1.6 to 2.0 parts by weight percent of a paraffin wax per 100 parts by weight of the polyvinyl chloride. The polyvinyl chloride pipe of the present invention comprises a concentration of paraffin wax lubricant (>1.5 parts per 100 parts polyvinyl chloride) heretofore unrecognized in the art, without the loss of key physical properties.

Abstract: 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 comprises a polyvinyl. 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.
