On November 12, the cracked C5 index declined by 4.58% compared to the previous week. The price index for downstream cracked C5 residual liquid fell by 10.97%. Among individual components, isoprene rose by 0.14%, piperylene decreased by 0.17%, and dicyclopentadiene (DCPD) increased by 0.58%. Overall, the decline in downstream cracked C5 residual liquid prices exceeded that of cracked C5 itself, leading to a notable increase in separation margins.
Looking ahead to next week, cracked C5 prices are expected to undergo a slight correction. Meanwhile, the price drop for cracked C5 residual liquid is projected to be more significant, causing theoretical C5 separation margins to narrow slightly.
