The reinforcing filler is constituted by crushes, powder or fibers of a cross-linked thermoplastic, in particular a radiation-crosslinked thermoplastic. The crushed, powdered, or fiber crosslinked polyethylene may be crushed, powdered or crosslinked polyethylene fibers, especially radiation crosslinked HDPE, or crosslinked polyamide, also crosslinked primarily by radiation. The particle size of the crushed or powdered crosslinked thermoplastic is preferably in the range of 0.2 to 5 mm. The crushed or powdered crosslinked thermoplastic may also preferably be a debris or powder of a crosslinked thermoplastic. The polymer composition comprises a polymer matrix based on at least one polymer component and at least 70% by weight of at least one reinforcing filler according to the invention. |
