Abstract:
A melt blend of HMW HDPE having a density in the range of about 0.945 to about 0.955 grams per cubic centimeter and MI values of about 0.01 to about 0.1 grams per 10 minutes and FRR of about 120 to about 280 selected from me group of virgin pellets, recycled, reprocessed, off specification, and wide specification grades of HDPE, and one or more than one of 1) a low molecular weight (LMW) HDPE homopolymer and 2) a LMW HDPE copolymer selected from the group of virgin pellets, recycled, reprocessed, off specification, and wide specification grades of HDPE, in a ratio in which the logarithm of the melt index (MI) of the blend equals the sum of 1) the products of each weight fraction of the HMW HDPE, the LMW HOPE homopolymer arid the LMW HDPE copolymer in the blend and 2) the logarithm of the MI of the respective HMW HDPE, LMW HDPE homopolymer and the LMW HDPE copolymer in the blend.
