| Polypropylene has a good combination of rigidity and toughness, high rigidity at elevated temperatures, can be stem sterilized, good abrasion resistance and low coefficient of friction, nonhydroscopic, excellent electrical properties, unique flex properties, good chemical resistance without stress cracking, one of the lowest densities, and high surface gloss. Polypropylene has the highest tensile strength of the olefins, high tensile modules, and relatively low impact resistance. Polypropylene has good fatigue resistance, excellent abrasion resistance and very low coefficient of friction comparable to nylon. However, lubricating nylon surfaces reduces the friction much more than for polypropylene. Polypropylene has excellent chemical resistance to dilute acids, concentrated acids (except oxidizing acids) alkalis, alcohols, detergents, and water. Polypropylene resists aromatic hydrocarbons, chlorinated hydrocarbons, greases, and oils at room temperature but is attacked at about 140°F. | ||
