Abstract:
1. A method of forming an anchorable mine roof support for anchoring in a borehole with resin or grout, comprising: placing an elongate metal member in a mold, the member having a first temperature at an outer surface thereof; injecting polymer into the mold, an inner surface of the mold having a second temperature different from the first temperature; forming a first semi-crystalline layer of the polymer proximate the outer surface of the member; forming a first substantially amorphous layer of the polymer proximate the inner surface of the mold; wherein the polymer forms a coating comprising post-consumer recycled thermoplastic disposed on the member, the post-consumer recycled thermoplastic having a portion with a thickness of at least about 1 mm; and wherein the coating forms a textured surface on the member.
