PP is a lightweight, semi-crystalline thermoplastic known for its excellent chemical resistance, high melting point, and good fatigue resistance. It is widely used in packaging, automotive parts, household goods, and industrial applications. PP is easy to process and recyclable, making it a popular choice for both injection molding and extrusion.
