Overview
Wacker Chemie AG is a German multinational chemicals company whose industrial roots extend back to 1914, when Alexander Wacker established a business for electrochemical industry in Germany. Its principal production base developed at Burghausen in Upper Bavaria, which remains the company's largest site and an important center for silicone, polymer, chemical, and semiconductor-related manufacturing. From an early focus on electrochemical materials and acetyl compounds, Wacker expanded into vinyl acetate and polyvinyl acetate, synthetic resins, silicones, silanes, semiconductor silicon, polysilicon, and biotechnology. The company is organized around businesses that use silicon and ethylene as major feedstocks. Wacker Silicones supplies silicone fluids, elastomers, sealants, specialty compounds, and related materials for construction, transportation, electronics, healthcare, textiles, coatings, paper, and consumer applications. Wacker Polymers produces dispersions and redispersible polymer powders, especially for mortars, tile adhesives, paints, coatings, flooring, and other construction products. Wacker Polysilicon manufactures highly purified silicon for solar and semiconductor wafers. Wacker Biosolutions applies biotechnology and fermentation processes to products such as pharmaceutical and food ingredients, while the group's historical semiconductor wafer activities were developed through Siltronic, which later became a separately listed company. Wacker's development has been marked by successive technology transitions. Vinyl acetate production began in the 1920s, the company developed a PVC manufacturing process in the 1930s, and silicone and silane production were established after the Second World War. Semiconductor activities began in the 1950s, followed by international expansion in Europe, North America, and Asia. The company also entered biotechnology in the 1990s and established Wacker Biotech in 2005. Its shares began trading publicly in Frankfurt in 2006. In 2015, Siltronic completed its initial public offering, separating an important part of the semiconductor-wafer business from the parent group. Wacker operates production and sales activities across Europe, Asia, and the Americas. Major German locations include Burghausen, Cologne, Halle, Jena, Nünchritz, and Stetten. International operations include sites in the United States, Brazil, China, India, Japan, South Korea, Norway, Spain, the Czech Republic, and the Netherlands. A major U.S. expansion in Charleston, Tennessee, brought a large-scale solar-grade polysilicon facility into operation in 2016 and was followed by an expansion for pyrogenic silica. The company serves industrial customers rather than primarily selling finished consumer goods, so its brand is most visible through the materials incorporated into construction products, electronics, solar technology, vehicles, coatings, adhesives, and medical or food applications. Wacker remains controlled by the Wacker family while operating as a publicly traded industrial group. Its current identity combines long-established German chemical manufacturing with specialized materials science, high-purity silicon production, polymer technology, and biotechnology. The company has also faced operational safety incidents at individual facilities, including events at its Tennessee polysilicon plant, which led to regulatory inspections, temporary shutdowns, emergency responses, and scrutiny of its communication with surrounding communities.
History
Wacker Chemie's history began on 13 October 1914, when Alexander Wacker founded Dr. Alexander Wacker, Gesellschaft für elektrochemische Industrie KG. A production plant was built at Burghausen in Upper Bavaria during the First World War, and the first acetaldehyde and acetic-acid products were manufactured there in December 1916. The company also made acetone and became an important supplier of materials associated with synthetic-rubber production. Shellac production began at Burghausen in 1922. The polymer business developed early. Willy O. Hermann established the Wacker Polymers business division in 1920, and vinyl acetate and polyvinyl acetate production began in 1928. In 1935, Herbert Berg developed a PVC manufacturing process. Wacker later sold that PVC process in 2000, as the group concentrated more heavily on specialty materials and higher-value technologies. Silicone chemistry became a major pillar after the Second World War. Wacker began producing silicones in 1947 and added silanes in 1949. In 1953, the business became a private limited company under the name Wacker-Chemie GmbH. That same year, Eduard Enk initiated the semiconductor business. Wacker produced its first silicon rod in 1955, and in 1960 built a new Cologne facility associated with the second Wacker process. These developments established the technical foundations for the later polysilicon and semiconductor-materials businesses. Internationalization accelerated from the late 1970s. Wacker Siltronic Corporation was founded in Portland, Oregon, in 1978, and the company expanded into Asia from 1983 onward. In 1987, Wacker created the wholly owned distribution subsidiary DRAWIN Vertriebs GmbH in Ottobrunn. The group continued to broaden its geographic reach through production, sales, and technical-service operations in Europe, North America, Latin America, and Asia. Wacker entered bioengineered products in 1990. This activity led to acquisitions and ultimately to the establishment of Wacker Biotech GmbH in 2005. Biotechnology complemented the group's established chemical businesses by allowing it to offer fermentation-based and bioengineered ingredients for pharmaceutical, food, and industrial customers. The company's legal and capital-market structure changed again in the 2000s. Wacker shares began trading on the Frankfurt Stock Exchange on 10 April 2006. At the end of 2007, Wacker acquired vinyl acetate/ethylene operations from Air Products Polymers, taking over activities in Allentown, Pennsylvania, and Calvert City, Kentucky. The transaction strengthened Wacker's position in polymer dispersions and related construction and industrial applications. Wacker commemorated its centenary in Munich in 2014. In 2015, Siltronic AG completed an initial public offering, marking a further separation of the semiconductor-wafer business from the parent group. Wacker subsequently continued investing in its core materials platforms. In the United States, it constructed a large solar-grade polysilicon plant in Charleston, Tennessee. Groundbreaking occurred in 2011 and production began in 2016. A later expansion added pyrogenic-silica capability and was completed in 2019. The Tennessee operations also brought safety and community-relations challenges. Construction-related deaths occurred in 2012, regulatory inspections in 2016 resulted in fines, and releases or accidents in 2017 and 2020 caused injuries. The September 2017 explosion at a hydrogen recovery unit led to road closures, shelter-in-place instructions, a temporary plant shutdown, and public concern over the contents of the visible cloud. Wacker stated that no hazardous chemicals had been released, while local officials and residents dealt with uncertainty during the emergency response. In 2022, Wacker opened a new U.S. headquarters in Ann Arbor, Michigan. The company today remains a family-controlled, publicly listed multinational focused on silicones, polymers, polysilicon, specialty chemicals, and biotechnology.
