Trisodium phosphate, also known as TSP, is a common chemical used in many industries, including cleaning and metalworking. It is also used as a food additive and preservative, and as a water softener. Common uses for TSP include cleaning and degreasing metal surfaces, whitening brick and concrete, and removing oxidation from aluminum.
When rubber is exposed to trisodium phosphate, the rubber can become weakened and brittle due to the chemical's corrosive properties. The rubber can also become discolored and brittle, leading to cracking or splitting. In some cases, the rubber can become permanently swollen, making it unable to be used. In addition, long-term exposure can cause the rubber to break down and become unusable.
