Abstract: Highly crosslinked polymer particulate and methods of manufacturing highly crosslinked polymer particulate. The highly crosslinked polymer particulate includes a plurality of crosslinked polymer granules. Each crosslinked polymer granule includes a highly crosslinked polymeric material and a property-modifying filler. The highly crosslinked polymeric material includes a plurality of polyethylene polymer chains and a plurality of chemical crosslinks. The the plurality of chemical crosslinks includes chemical crosslinks that covalently bond a given polyethylene polymer chain of the plurality of polyethylene polymer chains to another polyethylene polymer chain of the plurality of polyethylene polymer chains. The property-modifying filler is configured to modify at least one property of the plurality of crosslinked polymer granules. A characteristic dimension of each crosslinked polymer granule of the plurality of crosslinked polymer granules is at least 10 micrometers and at most 5 millimeters.
