  • Cumene Uses and Market Data - ICIS Explore

    Around 98% of cumene is used to produce phenol and its co-product acetone. However, the outlook for cumene is largely dependent on the performance of phenol's derivatives which have resulted in healthy growth rates for cumene. The largest phenol derivative is bisphenol-A (BPA) which supplies the ...
