| The process of cellular extrusion of thermoplastic materials is aimed at obtaining cellular shapes and coats with reduced density, presenting no hollows on the surface of extruder product and displaying minimal contraction under concurrent maintenance of properties similar to properties of products extruded by means of convertional method. The aim of the paper was to discover the influence of modifying HDPE with selected agents that is a blowing agent, in the course of the extrusion process, inclusive of determination how the modification affects selected physical properties and properties of the surface of HDOE extrusion product. Endothermic chemical blowing agents in the amount of 0.6% by mass were used in the research. The article present selected results of examination of changing the rotational speed of the extruder, melt flow rate (MFR) and microscopic structure. |
