Abstract
Extrusion process is one of the most popular polymer processing method. It allows to produce different types of shapes e.g. pipes, cables, plates, nets, films, coating, bars. This kind of shapes are usually made from typical thermoplastics materials like PVC, HDPF., LDPE, PP, PS, which characterizes solid physical structure. Nowadays, the most popular processing method is modification of plastic material with different types of agents. The modification consists of adding auxiliary agents takes place through the introduction of these materials during plastic processing or directly in its production. These measures include the modifiers primarily to improve physical toughness, thermal formabilitv or ductility. It could be flame retandant agent, flow agent, stabilizing agent, curing agent, filler, release agent, nucleant agent and blowing agent (porophor). The growing interest in porous plastic materials and their means of production led to the formation of a new method of processing, which is the microcellular extrusion process. This extrusion method of thermoplastics in recent years is one of the fastest grow ing methods of polymer processing. The aim is to obtain different microporous shapes and coatings with reduced density, without subsidence on the surface of extrudate and exhibiting minimal shrinkage while maintaining the similar nature of the products of extruded by a conventional method. Continuous development of microcellular extrusion process and the design elements comprising the technological lines creates new opportunities for research. Article presents a study of microcellular extrusion process and its efficiency during modification with blowing agent in the form of microspheres.
