XLPE Compound Natural

XLP13 is a silane cross-linkable polyethylene compound designed for low-voltage (≤1 kV) cable insulation.
When processed with its catalyst masterbatch CAT13N, it provides excellent mechanical strength, insulation performance, and long-term durability under standard extrusion and moisture-curing conditions.

XLP13 is a pre-grafted polyethylene compound intended for moisture-cure crosslinking in cable insulation.
When mixed with 5 % of its catalyst masterbatch CAT13N, it forms a high-quality XLPE insulation layer with excellent thermal and electrical properties.
This compound is ideal for low-voltage power and control cables (up to 1 kV) and is compatible with high-speed extrusion lines.
