There has been significant decline in olefins prices and aromatic products in this week. The constant decline in crude values has plummeted the immediate prices for Benzene and Toluene and Styrene. Crude oil prices fell steeply this year from 4 October, helping to push naphtha costs lower and putting pressure on prices downstream. In last one month Toluene prices has reduced by more than 20% and is likely to remain weak in this week as well.
