It is a thermoplastic polymer, meaning it can be melted and reshaped multiple times without losing its properties. Common uses include packaging, automotive parts, and textiles, making it an essential material in everyday products. This material is known for being lightweight, resistant to chemicals, and having a high melting point. Additionally, polypropylene can be easily colored and molded, which enhances its appeal for manufacturers. Its recyclability also contributes to its popularity in sustainable practices.
