High density Polyethylene QHJ02 for cable sheath
With the rapid development of the communication industry, the market demand for communication cables and optical fibers is about to increase, and the corresponding demand for raw materials is also getting higher and higher. Qilu Petrochemical high density polyethylene (HDPE) QHJ02 is specially designed for communication and fiber optic cable.
HDPE wire & cable grade has excellent mechanical and abrasion resistance properties. It has a strong ability to environment stress crack resistance and thermal stress crack resistance. It also has excellent insulating properties and processability, it is especially suitable for making high-frequency carrier cables, which can effectively avoid crosstalk interference and loss
Application
HDPE wire & cable grade is mainly used for producing communication cable jacket through fast-extrusion methods
