Abstract (English):
The study analyzes the thermal stability and mechanical characteristics of wood-polymer composite based on polypropylene at different temperatures. The results show the importance of taking into account the thermomechanical properties of WPC in the development of product molding technologies, allowing to predict the behavior of the material, minimize product defects and increase the stability of the technological process.
