Polypropylene, commonly known as PP, is a thermoplastic polymer used in a variety of applications ranging from packaging, textiles, automotive parts, and reusable containers. Its popularity stems from its versatility, chemical resistance, and recyclability. The density of polypropylene varies slightly depending on its crystallinity level and manufacturing process but generally falls within the range of 855 to 945 kg/m^3 (0.855 to 0.945 g/cm^3). This lightweight characteristic, combined with its strength, makes it an excellent choice for applications where weight savings are important without compromising on durability or chemical resistance.
