<jats:title>Abstract</jats:title><jats:p><jats:bold>Summary:</jats:bold> Silane grafting is one of the most recently used technologies in manufacturing crosslinked products due to its enormous advantages. In highspeed extrusion Polymer Processing Aid materials (PPA) additives are usually a copolymer of vinylidene fluoride and hexafluoropropylene. They are added during extrusion process to improve the process‐ability and to eliminate surface meltfracture that's occurred during processing of various polyolefin's resins.</jats:p><jats:p>In this paper an attempt was made to investigate the application of VTEOS (Vinyltriethoxysilanes) and VTMOS (Vinyl trimethoxysilane) as a replacement of PPA and to determine its improvement in high speed extrusion of Polyethylene cable. It has been found that silane did contribute to eliminate meltfracture and improvement has been made. Nevertheless interaction phenomenon with carbon black and other additives did influencing significantly the performance of the silane and minimized its efficiency. Rheological measurements confirm this behaviour.</jats:p><jats:p>Factors such as chemical reaction, physical adsorption and abrasiveness are involved in many of these situations. The presence of other storage stabilizer in the polyethylene contributes in negative way as well for formulation deficiency. Special attention in selecting the ingredient to minimize adverse effect is also very important in assuring optimum effectiveness.</jats:p>
