Polypropylene (PP) is a thermoplastic polymer made from the combination of propylene monomers. It is a rigid, semi-crystalline thermoplastic that is used in a wide variety of applications. PP has a relatively low density, making it the commodity plastic with the lowest density. It is used in both household and industrial applications due to its unique properties and ability to adapt to various fabrication techniques. Some of the uses of PP include plastic packaging, plastic parts for machinery and equipment, fibres and textiles, plastic furniture, low friction applications such as gears in machinery and vehicles, hinges on medication pots, lids on shampoo bottles, and other containers that will be bent and manipulated a lot and mustn’t break. PP is also used throughout the automotive industry for car dashboards, bumpers, cladding and exterior trims, and internal elements due to its lightweight and flexible qualities. PP is a recyclable thermoplastic polymer that is resistant to different chemical solvents, acids, and bases.
