Polyolefin plastomer (POP) prices on an FOB U.S. Gulf Coast basis declined *.*** month-on-month in July ****, a measured correction driven by the erosion of cost-side pricing support and concurrent structural demand headwinds across the residential and automotive segments. Despite a marginal uptick in ethylene, a *.** decline in hexene co-monomer costs — the alpha-olefin integral to metallocene-catalysed POP production — reduced overall production economics, removing the cost-floor justification that had previously sustained offered price levels and allowing market pricing to drift lower against a backdrop of subdued downstream activity.

Supply and demand dynamics remained under pressure during July. Ethylene prices increased slightly, but the impact was offset by a *.** decline in hexene prices, lowering overall production costs and eroding cost-side support for Polyolefin Plastomer (POP). Producers consequently had limited scope to pass higher costs through to buyers. On the demand side, the...
