On October 29, the pyrolysis C5 index rose by 0.91% compared to the previous week. The downstream pyrolysis C5 residual liquid price index increased by 6.20%, isoprene rose by 1.63%, piperylene increased by 2.36%, and dicyclopentadiene prices climbed by 4.12%. Overall, the price increases for pyrolysis C5 were weaker than those for its downstream products, leading to a significant rise in separation profits.
Looking ahead to next week, pyrolysis C5 prices are expected to see localized increases. However, given limited upward momentum for pentadienes, the price of pyrolysis C5 residual liquid is likely to remain stable, causing C5 separation profits to decline slightly.
