Application:
EJW70,EJW70C,EJW70A are thermoplastic low-smoke halogen-free flame-retardant insulation compounds, which don’t contain any heavy metal like
Pb, Ba, Cd, Cr, Sn and Sb. The properties can meet RoHS Standard. They have excellent mechanical and flame-retardant properties with temperature
resistant from -40℃to 70℃. They are mainly used for the insulation of communication cables, control cables and power cables.
Processing Indicator
Recommend to use special screw for low-smoke halogen-free compound with L/D=20-25.
