Application:
EHLZ is a kind of flame-retardant jacketing compounds with linear low density polyethylene resin as the basic raw materials. It is mainly used
as the jacketings of communication cables and control cables which have environmental-cracking resistant and flame-retardant requirements.
The highest working temperature is 70℃.
Processing Indicator
Recommend to use single-screw extruders with L/D= 20-25.
