Patent ID: 7683014

Claim:
A process for producing a lubricating stick, said process comprising the steps of: blending together a first formula comprising at least one first polymeric carrier selected from the group consisting of: a linear low-density polyethylene, low-density polyethylene, low density polyethylene, a polyolefin, and a synthetic wax and at least one lubricant powder; extruding said first formula into a plurality of first formula pellet-sized shapes; blending together a second formula comprising at least one second polymeric carrier selected from the group consisting of: a linear high-density polyethylene, high density-polyethylene, high-density polypropylene and a high-density methylpentene, and at least one lubricant powder; extruding said second formula into a plurality of second formula pellet-sized shapes; shaping said first formula pellet-sized shapes into a first formula portion; shaping said second formula pellet-sized shapes into a second formula portion; and joining said first and second formula portions together to form a lubricant stick having a first end portion consisting of said first formula and a second end portion consisting of said second formula.
