Abstract

The aim of the study was to determine the effect of the amount of nitrogen dosed in supercritical state to polymer melt on structure and physical properties of large-scale molded pieces from polyamide PA 6 GF30, obtained in the process of microcellular injection molding with gas dosage using MuCell® method. Apart from the reduction of the density at a level of about 15 % for samples with the highest nitrogen content, the increase of the impact resistance of samples PA 6 GF30 was observed. The other investigated mechanical properties were maintained at a good level.
