Polypropylene is a linear hydrocarbon polymer and one of the most versatile polymers available. It can be transformed through polymerization processes. When polymerized with ethylene, its chain structure is altered, improving impact strength and toughness. With a wide range of properties, this grade is well-suited for many applications, including films, injection molding, thermoforming, extrusion, and blow molding processes.
