XLP12BC is a pre-grafted polyethylene compound designed for moisture-cure crosslinking in cable insulation applications.
It is processed with its corresponding catalyst masterbatch CAT12N (5%) in standard extrusion lines.
The compound contains 2.5% carbon black for UV stability and weathering resistance, making it ideal for Aerial Bundled Cable (ABC) insulation.

Key Features & Advantages
Excellent weather and UV resistance (2.5% carbon black content)
Superior tensile strength and elongation
Reliable crosslinking through moisture exposure
Consistent extrusion performance and smooth surface finish
Complies with NF C 33-209, BS 7870-5, and IEC 60502-1

Processing Guidelines
Mix XLP12BC with CAT12N (95:5 ratio) at room temperature before extrusion.
Extrusion temperatures: 140–190°C (zone dependent).
Do not preheat or store premix for long durations.
Crosslinking by immersion in 90°C water (2–6 hrs) or steam (6–15 hrs).
