Abstract
The present invention is directed to a method of producing a cable protecting material. The method can include mixing and kneading an olefin-type polymer and suitable additives to prepare an olefin-type polymer composition, transforming the composition into pellets, and extruding the pellets at a temperature of from about 190° C. to about 250° C. The cable protecting material has a smoothly flowing skin and a well balanced material distribution. The cable protecting material also has good wear resistance.
