Beschreibung
Zusammenfassung:	A composition including 6 to 50 weight percent wood pulp fiber and 45 to 93.45 weight percent thermoplastic polymer. In some embodiments, the average dispersion of the wood pulp fibers within the thermoplastic polymer is equal to or greater than 90% as determined by the Dispersion Test. In some embodiments, the dilution level for detection in a bang at 40° C. is equal to or less than 450 as determined by ASTM E679. In some embodiments, the composition further includes 0.5 to 5 weight percent of an additive, such as a compatibilizer, a coupling agent, an anti-oxidant, and/or a lubricant. In some embodiments, the wood pulp fiber is bleached chemical wood pulp fiber.
