Application:
EHH is a kind of jacketing compounds with high-density polyethylene as the basic raw material, and mainly used for the jacketing of fibre
optical
cables and submarine power cables. The highest working temperature is 80℃.
EHM70 is a kind of jacketing compounds with medium-density polyethylene as the basic raw material, and mainly used for the jacketing
of communication cables, control cables, signal cables and fibre optical cables. The highest working temperature is 70℃.
EHL70 is a kind of jacketing compounds with low-density polyethylene as the basic raw material, and mainly used for the jacketing of
communication cables which is environmental stress cracking resistant, control cables, signal cables and power cables. The highest
working temperature is 70℃.
Processing Indicator
Recommend to process with the PE extruder with L/D is more than 25.
