In the study, an investigation was made into the hydrolytic degradation behavior of the
microporous polylactide (PLA) in the initial stage in three biological buffer solutions with …

Foam extrusion of polypropylene with a foaming agent, Expancel 950 MB 80 and 950 MB
120, was performed. The process was performed using a co-rotating twin screw extruder …

This paper presents a study of PVC-ceramic composites obtained by twin-screw extrusion.
Properties such as colour, wettability, tensile strength, elongation at break and impact tensile …

The article presents research of modification of PLA with four types of blowing agents with a
different decomposition characteristic. Modifications were made in both cellular extrusion …

Depending on the type and application, the coatings of power, electric, telecommunication
cables as well as other types of conduits are made of various kinds of polymer plastics …

The influence of the feed opening axis width and position in relation to the plasticizing
system axis on the effectiveness of the extrusion process of poly (vinyl) chloride has been …

The production of cellular coatings made of polymeric materials by the extrusion process
differs from solid coating extrusion in that the polymer produced by the process based on the …

We study some strength characteristics and the structure of porous polypropylene extrudates
obtained by the twin-screw extrusion. We use a ZSK-18 MEGAlab laboratory twin-screw …

The goal is to understand the influence of minerals fillers on the course and performance of
process of injection molding polypropylene compounds as well as on the mechanical …
