Different Levels

The mechanism of Environmental Stress Cracking (ESC) in polymers results from the interaction of three main elements: susceptible material, stress condition and a specific environment. The wide range of possible combinations of those three variables is what makes the ESC very difficult to predict and resolve. Therefore, this article intends to analyze the behavior of regions under stress of automotive tubes made with polyamide 12 exposed to a common degreaser material. Samples were manufactured through extrusion process and conditioned to different levels of stress before being exposed to the action of degreaser. The test results showed that aggressive fluids, like degreasing liquids, can be considered as catalysts of the Environmental Stress Cracking phenomenon in automotive tubes of polyamide 12.
