ABSTRACT:
An improved polyethylene fabric comprises polyethylene fabric or yarn that is manufactured by mixing HDPE (typically in pellet form) with pellets of cyclic-olefin polymers (COCs) in a ratio of up to 40% by weight of the layer. This mixture is then extruded in ways known to those skilled in the art. The resulting HDPE has superior stress and strain characteristics over a wider range of pressures and temperatures than conventional HDPE. The improved polyethylene fabric of the present invention is useful in applications where structural integrity is required and where pressure and temperature are a factor. For example, improved HDPE scrims of the present invention can be used as the reinforcing structure for irrigation hose or building fabric.
