<p>Melt blended HDPE compositions and blending methods applicable to the fabrication of HDPE products, such as single and dual wall corrugated HDPE pipe, fabricated and molded fittings and accessories, and other HDPE products are described. The compositions provide enhanced physical and processing properties and environmental stress crack resistance characteristics. The methods are useful with virgin or recycled homopolymer and/or copolymer HDPE resin components. The methods allow the selection and determination of relative weight fractions of HDPE blending components that provide specific physical properties and processing characteristics associated with density and melt index and specific values of environmental stress crack resistance associated with molecular parameters.</p> |
