Chemical, Weathering, and Abrasion Resistance Due to its non-polar nature, polypropylene shows a high resistance against chemical attack. The resistance of PP is nevertheless lower than that of PE because of its tertiary C atoms. PP is resistant against many acids, alkaline solutions, solvents, alcohol and water. Fats and oils swell PP slightly.
