KEY FINDINGS

COVID-19 IMPACT

Closure of End Use Industries Impacted the Market Evolution

The global COVID-19 pandemic has been unprecedented and staggering, with the polythiols market experiencing lower-than-anticipated demand across all regions compared to pre-pandemic levels. The sudden rise in CAGR is attributable to the market's growth and demand returning to pre-pandemic levels once the pandemic is over.

The market for polythiols was halted by COVID-19 due to several aspects of the pandemic. Primarily, the lockdown restrictions disrupted the supply chains as well as the closure of end use industries decreased the demand for polythiol which slow downed the growth of the market. However, post-pandemic in 2022, the market started to gain momentum in the demand and the supply chain due to the growth of the key application industries and it is expected to remain progressive in the coming years as well.
