Polypropylene impact copolymers are thermoplastic resins produced by polymerizing propylene and ethylene using Ziegler-Natta catalysts. This results in a heterophasic structure, with an amorphous phase dispersed within a semi-crystalline polypropylene matrix—delivering enhanced impact resistance and versatility.

These materials can be processed using various technologies, including injection molding, blow molding, film and fiber extrusion, sheet extrusion and thermoforming. LYB impact copolymers are widely used in packaging, housewares, film, pipe, automotive and electrical applications.
