Application:
EHW90GD is high flame-retardant low-smoke halogen-free jacketing compound, which doesn’t contain any heavy metal as Pb, Ba, Cd, Cr,
Sn and Sb. Its properties can meet RoHS Standard. The Product has excellent physical and mechanical properties, especially good high
flame-retardant performance with temperature rating from -40℃to 90℃. It is mainly used for the jacketing of communication cables, control
cables and power cables, which can pass VW-1 flame-retardant level.
Processing Indicator
Recommend to use special screw for low-smoke halogen-free compound with L/D=20-25.
