Semi-conductive compounds

Semi-conductive layers, internal, external are designed to protect XLPE, EPR insulation layer.

They are blends of Lotryl BA resins and carbon black (up to 40%).


To avoid premature cable failure due to insulation breakdown, Lotryl® semi-conductive layers ensure:

  • Good thermal stability for extrusion and curing steps
  • Good adhesion to the conductor and insulation layer
  • Smooth and homogenous carbon black dispersion
  • Easy processing during compounding and extrusion steps
  • Excellent peroxide cross-linking reactivity

High fluidity Lotryl 35BA320 allows compound viscosity adjustment.


Recommended Lotryl® grades:  
17BA04 35BA320
