Abstract

The authors study the effect ionizing and UV radiation have on the physico-mechanical characteristics of polymer materials based on Tarkosil® SiO2 nanoparticles and injection molded polyurethane with different storage times of the initial components. It is shown that because of exposure to ionizing radiation (1000 Gy), the tensile strength and elongation of polyurethane based on components manufactured 1 month before the synthesis of samples rise to 30% (from 23 to 30 MPa) and 65% (from 382 to 627%), respectively. The effect such external factors as UV and ionizing radiation have on the performance of products and parts based on injection molded polyurethane is studied to improve their physical and mechanical properties.
