Application:
EHW70, EHW70C, EHW70A are thermoplastic low-smoke halogen-free jacketing compound, 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 jacketing 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.
