Abstract
Certain embodiments of the present technology provide a cable comprising a conductor and a cable layer. The cable layer comprises a polypropylene material. The cable layer and/or the polypropylene material comprise a crystalline fraction crystallizing in the temperature range of 200 to 105° C. determined by stepwise isothermal segregation technique. The crystalline fraction comprises a part, wherein, during subsequent melting at a melting rate of 10° C./min, the part melts at or below 130° C. and the part represents at least 20 percent by weight of the crystalline fraction. In certain embodiments, the part melts at or below the temperature T=Tm−3° C., wherein Tm is the melting temperature of the cable layer and/or the polypropylene material, and the part represents at least 45 percent by weight of the crystalline fraction. Certain embodiments provide methods and processes for manufacturing the cable described above and herein.
