This paper introduced the properties of linear low density polyethylene (LLDPE) TJDL-9270 in the application as cable base resin and its development process. Based on the requirements of processability and mechanical properties for cable application, the target properties of the resin, technical route and reaction conditions were determined. The difficulties in production of F catalyst were analyzed; the key control factors in the product transition procedure were presented. The LLDPE resin so prepared features of wide relative molecular mass distribution, easy processability, stable quality, high surface gloss and outstanding mechanical properties and resistance to environmental stress cracking, completely satisfying the requirements for manufacturing cable in the mode of high speed extrusion.
