Application:
EHW90GS is low-smoke halogen-free flame-retardant jacketing compound which has high speed extruding performance. It doesn’t contain any
heavy metals like Pb, Ba, Cd, Sn and Sb. All its properties can meet RoHS Standard. It has excellent physical and mechanical properties, especially
good extruding characteristic. This product can be used with temperature resistant from -40 ℃to 90 ℃. It is mainly used for the jacketing of net-cables,
fibre-optical cables and other small-square meter cables, which have high speed extruding requirements. Also it can be used for the jacketing of
ordinary 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.
