Polypropylene (PP) - Granular

Polypropylene (PP) granules are raw thermoplastic resin pellets produced through the polymerization of propylene monomers. Known for their lightweight, chemical resistance, and excellent processability, these granules serve as a primary feedstock for injection molding, extrusion, and blow molding applications. PP offers a remarkable balance of mechanical strength, heat resistance, and flexibility, maintaining stability under a wide temperature range and resisting fatigue from repeated bending. Its low density (approximately 0.91 g/cm³) makes it a cost-effective and energy-efficient material for large-scale production. Additionally, polypropylene is non-toxic, recyclable, and environmentally safe, emitting no harmful gases during processing. Commonly used in the manufacture of rigid packaging, automotive components, fibers, and consumer products, PP granules remain one of the most versatile and sustainable polymer materials in modern industry.
