Also known as Vinnolit and Vinnolit GmbH & Co. KG.
chemXplore tracks 9 projects involving Westlake Vinnolit.
Westlake Vinnolit's role on them: Owner, Operator, and Technology licensor.
Closure driven by weak demand, high energy costs and import pressure; 165,000 t/yr PVC capacity affected; Q1 2027 shutdown and ~$205m pre-tax charges.
Completed acquisition of Wilhelmshaven PVC/VCM site with 380,000 t/yr PVC capacity on Germany’s North Sea coast and a deep‑water dock for raw‑material supply.
The Burghausen plant now uses microsuspension for flexible PVC production. Investments include new reactors, a dryer, expanded control room, silos, and a recycling system for cooling water.
The Gendorf site will see increased chlorine and VCM capacity using energy-efficient technology, enhancing the value chain and reducing VCM transport, benefiting customers with more caustic soda.
The acquisition includes six production sites in Germany and the UK, adding significant PVC, VCM, and caustic soda capacity. Vinnolit will operate under its name, retaining its headquarters and 1,400 employees.
The Burghausen plant's PVC production capacity increased to 100,000 tons annually, enhancing market position. Key markets include Eastern Europe, Turkey, China, India, and Brazil.
The conversion to membrane technology boosts chlorine capacity to 430,000 tonnes/year, enhances PVC raw material supply, and improves caustic soda delivery, increasing energy efficiency and reducing CO2 emissions.
