Polypropylene is a thermoplastic polymer commonly used in various applications such as food packaging, plastic furniture, films, automotive parts, medical devices, upholstery, and industrial and manufacturing applications. It is a manufactured material known for its strength, affordability, durability, and resistance to moisture, color loss, degradation, and chemicals. Polypropylene is a commodity plastic, making it inexpensive and often disposable. It is also used in nonwoven fabrics, and its unique properties make it suitable for applications where moisture transfer is desired, such as in clothing and diaper components. Polypropylene is a partially crystalline and non-polar material with high chemical resistance and is the second-most widely produced commodity plastic after polyethylene. It is also used in nonwovens, with over 50% used for diapers or sanitary products where it is treated to absorb water rather than repelling it.
