Widely used as a catalyst in polymerization reactions, especially in the production of polyolefins such as polyethylene and polypropylene. It enables controlled molecular weight and stereoregularity in the resulting polymers, making it valuable in manufacturing plastics with specific mechanical and thermal properties. Commonly employed in solution, slurry, and gas-phase polymerization processes due to its high activity and stability under industrial conditions. Also used in specialty chemical synthesis where zirconium-based catalysts are required for selective transformations.
