Our cable grade talc powder is a specially surface-modified inorganic filler designed for wire and cable insulation and sheath materials. With high purity, low moisture content, fine and uniform particle size, it features excellent insulation performance, heat resistance and chemical stability. After professional activation treatment, the talc powder shows superior compatibility and dispersion with PE, EVA, PVC, LSZH and rubber cable materials.
It effectively improves the tensile strength, rigidity, dimensional stability and aging resistance of cable compounds, while reducing material shrinkage and production cost. Meanwhile, it helps enhance flame retardant synergy and processing fluidity during extrusion. This talc powder is widely applicable for low-smoke zero-halogen cables, PVC insulated wires, rubber sheathed cables and other wiring products, ideal for customers requiring stable cable mechanical and electrical performance.
