Abstract


This study analyzes the influence of industrial factors on polyvinyl chloride material, focusing on mechanical and elastic changes caused by different test environments. on polyvinyl chloride material is widely used due to its low cost and versatile chemical properties, but exposure to various environmental factors can significantly affect its performance. In the research, on polyvinyl chloride specimens were tested by uniaxial tensile testing after exposure to distilled water, cooling oil, saline, and ultraviolet radiation type C. The samples were immersed in liquid during the 24 hours, followed by mechanical testing according to ISO 527-2 and ISO 62:2008. The results showed that distilled water and cooling oil resulted in an increase in the maximum stress supported, while ultraviolet radiation type C and saline caused a significant reduction in mechanical strength. Statistical analysis performed with Minitab 18 confirmed the normal distribution of the data and allowed the identification of outliers. The study highlights the need to select materials according to the conditions of use, preventing premature degradation of on polyvinyl chloride components in aggressive industrial environments.
