Application:
SEJ90-2-N,SEJ90-2-M are two-step silan cross-linkable 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℃.
SEJ90-2-N is suitble for squeeze tube mold production process.
SEJ90-2-M is suitble for extrusion diess 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.
