Overview:Today, PV-grade EVA prices remained stable for the time being. Cost side, upstream ethylene market moved sideways and exerted no clear directional pull on EVA resin production costs in the near term; supply side presented an offsetting pattern, as one leading petrochemical unit was shut down for maintenance, while another leading EVA unit was about to start up, and the marginal change in actual effective supply still needed to be monitored. Market outlook, US-Iran geopolitical tensions may feed through crude oil to create cost-side uncertainty, while the evolution of the supply-demand pattern remains the core variable and requires continued tracking.
