PVC/WOOD FIBER COMPOSITE

摘要

PVC/wood fiber composites are comprised of (1) wood fibers; and (2) a composite comprising PVC, a polyester and a lubricant package comprised of one or more polyol esters, polyols, fatty acid esters of aliphatic or aromatic dicarboxylic acids, fatty acid salts, fatty alcohols, hydrogenated fatty acid glycerides and combinations thereof. The composites are easier to process than conventional composites because they require lower extruder torque that translates into less work and corresponds to lower process temperatures.
