polypropylene, a synthetic resin built up by the polymerization of propylene . One of the important family of polyolefin resins, polypropylene is molded or extruded into many plastic products in which toughness, flexibility, light weight, and heat resistance are required. Polypropylene (PP) is a thermoplastic polymer derived from propylene monomer. It is partially crystalline, non-polar, and resistant to fats and organic solvents. It has various applications in packaging, textiles, automotive, and other industries. Polypropylene is known to have a high melting point, making it an ideal material for the construction of microwave-friendly containers. Polypropylene is chemically resistant towards water, alkalis, and acids. This polymer is also quite resistant to stress and cracking, even when it is flexed. This is the reason why polypropylene is widely used in the construction of hinges. Polypropylene exhibits high resistance to wear and tear. Therefore, this polymer is highly durable.
