Used as a catalyst precursor in olefin polymerization, particularly in the production of high-density polyethylene (HDPE) and linear low-density polyethylene (LLDPE). It is effective in coordination polymerization when activated with cocatalysts like methylaluminoxane (MAO). The compound supports the formation of polymers with controlled molecular weights and narrow polydispersity, making it valuable in industrial plastic manufacturing. Its hafnocene structure offers higher thermal stability and activity in certain conditions compared to analogous zirconocenes.
