Our independently developed black polyethylene (PE) sheathing material offers outstanding performance, including high mechanical strength, excellent low-temperature properties, superior environmental stress cracking resistance, and remarkable weather resistance and toughness. During production, there is no die lip buildup, and the material exhibits excellent antioxidant properties with a long oxidation induction time (OIT). It also contains low-moisture-absorption carbon black to further enhance its performance. We can now supply black HDPE, black LLDPE, and black MDPE sheathing materials according to different customer requirements.
