Polypropylene is a polymer plastic material. Polypropylene will not rust, pit, scale, or corrode. Polypropylene's chemical resistance and thermal resistance
properties provide resilience and durability. Aqueous solutions of acids, alkalis, and salts; a large number of organic solvents; mineral acids including the oxidizing acids such as nitric and sulfuric can all be held by polypropylene liners because of this material's chemical resistance properties. Polypropylene can also resist bacterial growth, oils, and high temperatures. It possesses good fatigue strength..
Polypropylene does not need to be painted and does not need electrolysis.
