Product Description
LE7704 is a thermoplastic black polyethylene compound, specially designed for semiconductive screen applications.

LE7704 is intended for semiconductive applications in medium voltage cables.

LE7704 meets the applicable requirements as below when processed using sound extrusion practice and testing procedure:
  • IEC 60502
  • ISO 1872-E/BA, KHXY, 23-G200, C40

LE7704 is a ready-to-use black compound. The good distribution of carbon black and additives in LE7704 would result in a chemically clean and smooth semiconductive screen.
