Four weeks into war: Polymer rally hits multi-year highs, momentum slows; are further hikes ahead in April? by Esra Ersöz
The final week of March, marking one month since the outbreak of the war in the Middle East, began with a sharp pullback in crude oil following the steep gains seen during the first three weeks. This triggered renewed volatility across the upstream chain, where feedstocks and monomers have borne the brunt of the impact. Meanwhile, the rally largely persisted on the polymers side, although its pace appears to have eased in several products... 31-03-2026
Three weeks into the war, polymer markets extend sharp gains; how will week four unfold amid crude plunge? by Esra Ersöz
Three weeks into the Middle East war, global polymer markets have continued to post sharp gains, extending the rally triggered by the initial disruption to regional supply flows. What began as a supply-driven shock has now evolved into a broader cost-push inflation cycle across the petrochemical chain, with both feedstocks and polymers surging in tandem... 24-03-2026
Two weeks into the war: Asia and Türkiye bear the brunt of petrochemical shock by Esra Ersöz
Two weeks into the Middle East war, the ripple effects across the global petrochemical chain are becoming increasingly clear. The region’s role as a key exporter of crude oil, LNG, propane and polyolefins has quickly transmitted supply shocks to markets around the world. Prices for feedstocks, monomers and polymers have all moved sharply higher as supply risks and logistics disruptions ripple through the chain... 16-03-2026
Türkiye’s polymer markets shoot up on supply crunch, soaring costs by Merve Madakbaşı
March has turned into a turbulent month for Türkiye’s polymer markets, with supply disruptions triggering price hikes rarely seen in recent years. Rising tensions in the Middle East in the final days of last month not only pushed supply chains into turmoil but also drove production costs into one of their most volatile periods in years... 13-03-2026
Asia petchem chain rattled by Hormuz disruption as plants curb output, supply fears mount by Elif Sevde Yalçın and Esra Ersöz
The escalating conflict in the Middle East is sending shockwaves through Asia’s petrochemical industry, disrupting feedstock supply chains and forcing producers to adjust operations across the region. With shipping routes around the Strait of Hormuz severely affected, deliveries of crude, naphtha, LPG, and other key raw materials have been delayed, triggering force majeure declarations, plant shutdowns, and reduced operating rates at multiple facilities... 12-03-2026
Polystyrene (PS) is formed by the polymerization of styrene feedstock. As styrene is formed by adding ethylene into the benzene feedstock, benzene and ethylene prices are also taken into consideration, in addition to styrene while examining the production costs of PS.
There are two types of PS, namely GPPS and HIPS. These are divided into subgroups as injection and extrusion. While plastic hangers, protective foam, disposable cutlery, CD boxes are made of GPPS, HIPS is used in white goods and electronics.
The world's largest PS buyer is again China by a long way. As of 2020, China alone carries out 35% of global imports. It was followed by Malaysia and Germany, with 6% and 5% shares, respectively. Taiwan ranks first among the top PS importers list, followed by Belgium and France.
ChemOrbis Polystyrene (PS) prices and Plastics News section contain information on the market trends, as well as supply-demand factors and production costs that determine the pricing, statistics on imports and exports, along with maintenance shutdowns, restarts, and new capacities related to PS facilities.
