Description and Application 產品描述和用途
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.
