At what maximum temperature can plastic materials be used for water service?

Plastic materials are commonly utilized in water services due to their corrosion resistance, lightweight properties, and flexibility. However, they have limitations regarding temperature endurance. The correct maximum temperature for the use of plastic materials in water service applications is 60°C. At this temperature, typical plastics can maintain their integrity and perform effectively without significant risk of distortion, degradation, or loss of mechanical strength.

If exposed to temperatures above 60°C, many plastic materials may start to soften, deform, or even melt, compromising the functionality and safety of water systems. Thus, understanding the thermal properties of plastics is critical for ensuring they are only subjected to appropriate conditions within their operational limits.
