LDPE/MDPE/HDPE Jacketing Compound
Product Introduction
OW-EHH is a kind of jacketing compounds with high-density polyethylene as the basic raw material, and mainly used for the jacketing of fiber optical cables and submarine power cables. The highest working temperature is 80℃.
OW-EHM 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 fiber optical cables. The highest working temperature is 70℃.
OW-EHL 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.
