Application:
SEJ90-2-KK(N) is two-step silane cross-linkable polyethylene insulation compound for low-voltage cables. It is mainly used for the insulation of
low-voltage overhead cables through squeeze tube mold production process. Cables working voltage is 3KV and below, the highest working
temperature is 90℃. The color of this product is black if there are no speical explanations.
Processing Indicator
Recommend to process with the PE extruder.
