Abstract

Bu bulus, bir polietilen bir bilesim tabakasi içeren bir kablo hakkinda olup burada polietilen bilesim sunlari içerir: (A) toplam bilesimin agirligi üzerinden %5 ila %95 en azindan bir ilk polimer olup bu polimer asagidakilere sahip bir etilen /alfa-olefin interpolimerdir: (i) 0.865g/cm3 ila 0.95 g/cm3 yogunluk, (ii) 3.5' ten az, özellikle 1.8 ila 2.8 arasinda bir moleküler agirlik dagilimi (Mw/Mn), (iii) 0.001 g/10 dak. ila 10 g/10 dak. Arasinda bir erime indeksi (I2), (iv) %50' den daha fazla bir CDBI; ve (B) toplam bilesimin agirligi üzerinden %5 ila %95 en azindan bir ikinci polimer olup bu polimer heterojen bir sekilde dallanmis bir etilen polimer ya da 0.9 g/cm3 ila 0.965 g/cm3 arasinda bir yogunluga sahip bir homojen etilen homopolimerdir. Bu bulustaki kablo, düsük yogunluklu polietilen (LPDE), lineer düsük yogunluk polietilen (LLDPE) ve polivinilklorit (PVC) gibi polimerleri kullanan konvansiyonal kabloya göre çok iyi mekanik özelliklere ve islenebilirlige sahiptir.The present invention is about a cable comprising a polyethylene composite sheet, where the polyethylene composite offers: (A) 5 to 95% over the total composition weight of at least one polymer, which is an ethylene / alpha-olefin interpolymer having: ( i) 0.865g / cm3 to 0.95 g / cm3 density, (ii) a molecular weight distribution (Mw / Mn) of less than 3.5, especially 1.8 to 2.8, (iii) 0.001 g / 10 min. to 10 g / 10 min. A melt index (I2), (iv) of more than 50% of a CDBI; and (B) at least 5% to 95% of the total composition over a weight of at least a second polymer, which is a heterogeneously branched ethylene polymer or a homogeneous ethylene homopolymer having a density between 0.9 g / cm3 and 0.965 g / cm3. The cable in this invention has very good mechanical properties and processability compared to conventional cable using polymers such as low density polyethylene (LPDE), linear low density polyethylene (LLDPE) and polyvinylchloride (PVC).
