Chemical stability is another major advantage of PP sheet: it is resistant to most acid, alkali, and salt solutions (such as sulfuric acid below 80% concentration and sodium hydroxide at 20%), as well as organic solvents (with a few exceptions, such as concentrated nitric acid and chloroform). This makes it a preferred choice for applications such as chemical tank linings and laboratory countertops.
