Styrodur is a closed-cell, extruded polystyrene foam board that is resistant to water and moisture, which helps to prevent the migration of plasticizers. Additionally, Styrodur is designed to withstand the pressure and weight of a pool, making it a suitable choice for this application. However, it is important to ensure that the Styrodur is properly installed and that any seams or joints are sealed to further minimize the risk of plasticizer migration. **

The soles of sneaker shoes dissolve or crumble due to hydrolysis, which is the chemical breakdown of a compound due to reaction with water. In this case, the plasticizer in the soles of the shoes is susceptible to hydrolysis, causing it to break down and lose its ability to hold the material together. This can lead to the disintegration of the soles, resulting in them becoming soft, sticky, or crumbling. Over time, exposure to moisture and other environmental factors can accelerate the hydrolysis process, causing the soles to deteriorate. **
