Wacker production plant for dispersible polymer powders goes on stream in South Korea


Following a construction phase lasting 20 months, Wacker Chemie AG has brought a new spray dryer for the production of dispersible polymer powders on stream in Ulsan, South Korea. The plant is part of an ongoing site expansion aimed at boosting the company’s production capacity for dispersions and dispersible polymer powders in Asia.

Wacker is a world-leading producer of polymeric dispersions and dispersible polymer powders, which are important ingredients in the manufacture of building materials. Construction is currently booming in Asia. Growing just as strongly is the demand for high-quality, energy-efficient, sustainable construction solutions. This has prompted the Group to invest in the region and expand its production capacity.

Wacker already produces vinyl acetate-ethylene copolymer (VAE) dispersions in Ulsan. The new spray dryer converts liquid dispersions into dispersible polymer powder by feeding them through an atomiser into a stream of hot gas, which dries them extremely quickly to yield a fine powder. The new plant will have a total capacity of 80,000t/yr. On completion, the spray dryer will be one of the two largest of this kind in the world. The second plant with this capacity is located at Wacker’s Burghausen site. The new spray dryer will create some 50 new jobs in Ulsan.
