Patent ID: 7632888

Claim:
A feedstock concentrate material, comprising: a first phase including fibers having an average length greater than about 5 mm; and a polymeric phase including at least 50 percent by weight of the polymeric components of the polymeric phase of a first polyolefin having a first melt flow rate; and less than 50 percent by weight of the polymeric components of the polymeric phase of a second polyolefin having a second melt flow rate that is higher than the first melt flow rate; wherein the fibers in the first phase include glass fibers, the first polyolefin includes a polypropylene and the second polyolefin includes a polypropylene; wherein the feedstock concentrate material further comprises a polypropylene-based coupling agent, and the feedstock concentrate material is in the form of pellets, rods, or granules; wherein the fibers in the first phase are aligned generally axially with each other; wherein the first polyolefin is a polypropylene having a melt flow rate of less than about 60 g/10 mm, as measured per ISO 1133 at 230° C./2.16 kg, the second polyolefin is a polypropylene having a melt flow rate greater than about 300 g/10 mm, as measured per ISO 1133 at 230° C./2.16 kg, and the first polyolefin is present from about 3 to about 9 parts by weight per 1 part by weight of the second polyolefin.
