ABSTRACT:
A porous flexible hose primarily of crumbed rubber and synthetic rubber reclaimed from rubber tires, ground to a relatively small granular size, with metal removed; such as, for example, would pass through a 30-mesh screen, process-mixed through an extruder, with a much smaller binder mix of primarily polyethylene, in the order of 25% by weight, and with approximately 0.5% of the mixture added sulphur and 0.5% oil that can be random mixed grades of automobile engine oil. The resulting product is useful as a soil watering soaker hose that has a high degree of flexibility along its length. It is a water leaking soaker hose formed in the process through the extruder with limited foaming from steam originating from absorbed moisture in the crumbed, reclaimed rubber tire material, and from residual gases venting from the material mix, with product mix heating in the extruder, forming some open cell fluid flow paths. The foaming with steam and gases from the mix also form labyrinth passageways between the rubber tire granules and the polyethylene binder mix, and also through the binder mix that is non-compatible with the rubber granules but that forms a physical interconnective structural material binder therefor.
