Black low density polyethylene jacketing compound for energy and communication cables

LE6025 is a black low density copolymer modified polyethylene compound. It is characterized by excellent stress crack resistance and mechanical properties and low temperature performance in combination with good extrudability.

LE6025 contains 2,5% well dispersed furnace black of nominal particle size less than 25 nanometres in order to ensure excellent weathering resistance.

Applications

Jacket for energy and communication cables
