Key Findings

COVID-19 Impact

Pandemic Impeded Market Growth as Companies Have Shut Down

The global COVID-19 pandemic has been unprecedented & staggering, with spherical alumina fillers experiencing lower-than-anticipated demand across all regions compared to pre-pandemic levels. The sudden spike in CAGR can be attributed to demand returning to pre-pandemic levels after the pandemic is over.

The global spherical alumina filler market has experienced an unprecedented slump in its market growth post the pandemic. Several manufacturers have shut down worldwide operations due to the losses incurred during the pandemic as manufacturing and processing units came to a halt. Thus, supply chain disruptions in the global market have severely affected product demand, leading to a slowdown in chemical manufacturing and industrial production.
