Polymer prices rose in October 2026 as raw-material cost pressure continues
Rising naphtha, ethylene and propylene contract prices fed through into inputs like LDPE and benzene; weak demand and high inventories are capping the increases.
Polymer prices moved higher in October 2026 on the back of rising raw-material costs. Higher naphtha prices in particular led polyolefin producers to seek increases in ethylene and propylene contract prices. The LDPE monomer price rose by 80 euros per tonne, while the benzene contract price climbed 261 euros versus September to 1,195 euros per tonne. Weak end-demand and high inventory levels are, for now, limiting how far the increases can run. Recycled feedstocks stayed broadly stable, with only a limited increase seen in high-quality recycled grades.
What does this mean for a molder?
Raw-material cost is a major share of input pricing, so short-term cost pressure is real for processors without fixed-price contracts. Recycled material staying relatively stable may make recycling and regrind management a more attractive option during this period.
