In this work, I aim to examine the various influences of process parameters on the physical and
mechanical properties of extruded polystyrene. Since XPS belongs to the group of thermoplastic
polymers, its properties are significantly affected by thermal treatment, particularly temperature
and pressure. However, in addition to these key factors, this paper also aims to examine the
impact of other parameters. Production, sampling, parameter monitoring, and sample testing
were conducted in the production facility and the laboratory for construction materials within the
TEMAX BH d.o.o. company. The findings of this research are expected to provide valuable insights
into optimizing manufacturing conditions to enhance XPS performance, thereby improving
material efficiency and expanding its potential applications in the construction and insulation
industries.
