Abstract:
1. A method of manufacturing an object, the method comprising the steps of: providing a mixture of approximately 50% to 80% by weight crumb rubber which is between 10 mesh and less than 20 mesh crumb rubber and 18% to 40% by weight polyolefin having a melting index ranging between approximately 5 g/10 minutes and approximately 50 g/10 minutes; feeding the mixture of crumb rubber and granular polyolefin into a barrel and screw; heating the mixture of crumb rubber and granular polyolefin in the barrel to a temperature between 150° C. and 220° C. to produce a heated mixture of crumb rubber and melted polyolefin; conveying the heated mixture of crumb rubber and melted polyolefin along the barrel towards a nozzle; and injecting the heated mixture of crumb rubber and melted polyolefin through the nozzle into a mold so that melted polyolefin solidifies and forms a matrix about the crumb rubber.
