Polypropylene (PP)
Description
Polypropylene is a versatile thermoplastic polymer known for its excellent balance of properties. It offers good chemical resistance, high tensile strength, low density, and good fatigue resistance. PP can be processed using various methods like injection molding, extrusion, and blow molding, making it suitable for a vast range of applications from consumer goods and packaging to automotive components and textiles. It is also recognized for its recyclability and relatively low cost.
