Abstract:
1. A plastic or polymer composite article formed from an immiscible polymer blend comprising 60% or greater of a high density polyethylene (HDPE) matrix phase and 40% or less of a polycarbonate (PC) phase, wherein: said PC phase of said immiscible polymer blend consists essentially of fiber-shaped domains having a length-wise dimension aligned essentially parallel in said HDPE matrix phase; said HDPE has a melt flow at 190° C./2.16 Kg of less than 1 g/10 min, and said PC has a melt flow of an injection molding grade PC, the ratio of HDPE to PC provides a blend having a modulus greater than the additive contribution of each polymer to overall stiffness and the amount of HDPE and the amount of PC when added together equal 100%.
