Application:
ZSEJ90-2-N,ZSEJ90-2-M4 are two-step silane cross-linkable PE insulation compounds for low-voltage cables. They are mainly used for the
insulation of low-voltage cables and control cables with working voltage for 3KV and below. The highest working temperature is 90℃.
ZSEJ90-2-N is suitble for squeeze tube mold production process.
ZSEJ90-2-M4 is suitble for extrusion dies mold production process.
Above two models have the same physical and electrical properties, except different production molds.
Processing Indicator
Recommend to process with the PE extruder.
