ABSTRACT:
A method for producing a molding compound for the manufacture of highly wear resistant parts first mixes high-molecular low-pressure polyethylene particles with particles of a cadmium salt and titanium dioxide. The mixture is rapidly raised in a high speed mixer to a temperature of between 105.degree. C and 108.degree. C at which point glass micro-beads having diameters of the order of 50 micrometers are added. This mixture is then fed into a sintering press in the form of a web of plate thickness wherein it is compressed in stepwise increments to a pressure of 100 kgf/cm.sup.2 and heated to about 180.degree. C. This is followed by a cooling step which depends on the desired crosslinking of the molecular chains.
