A new era began for the WACKER Group in April 2006. Wacker Chemie AG shares were traded on the Frankfurt Stock Exchange for the first time on April 10. The IPO saw WACKER placing 14.99 million shares with institutional and private investors. At €80, the issue price was set at the upper end of the price range. Advance demand was huge. The shares issued were over-subscribed more than 18 times. Since the IPO was held, the family shareholder continues to keep its majority stake in the company.
Knowledge Management for Customers, Partners and New Employees
Founding of the VINNAPAS® ACADEMY. This later became WACKER ACADEMY, which is currently operating at 15 sites across the globe, providing on-site knowledge transfer about handling WACKER products and their applications.
Founding of the WACKER Relief Fund
A charitable organization that provides aid for victims of natural disasters. The aim is to provide fast and unbureaucratic aid. The main focus is helping children by building or repairing schools or orphanages.
Construction of Pilot Plant for Granular Polysilicon
These innovative little pellets are needed to manufacture silicon monocrystals. As they are easy to meter, they constitute a considerable improvement to the “poly chunks” used before. These serrated, irregular pieces had to be filled into the crucible by hand.
A New Site in Saxony, Eastern Germany
By purchasing a plant in Nünchritz, Saxony, WACKER acquired an important new site for silicones – and created ideal conditions for the production of innovative silicone products. Over the following decade, the site was gradually expanded. Today, it is one of the three WACKER sites worldwide that produce hyperpure polycrystalline silicon.
WACKER SILICONE AWARD for the Fathers of Silicones
Richard Müller and Eugene Rochow were honored with the WACKER SILICONE AWARD. From 1942, independently of each other, both developed direct synthesis for dimethyldichlorosilane – the forerunner of WACKER’s over 3,000 different silane and silicone products.
WACKER Moves to New Headquarters
Group HQ has been based in the Neuperlach district of Munich ever since.
Production of Bioengineered Products Begins
The inauguration of the biotechnology research center for manufacturing compounds for the pharma, food and agricultural sectors heralds the age of biotechnology.
Founding of DRAWIN Vertriebs-GmbH
In May 1987, DRAWIN Vertriebs-GmbH was founded as a wholly-owned subsidiary of Wacker Chemie AG. It took over some areas of WACKER SILICONES business division's logistics and distribution planning. DRAWIN’s product range now includes around 1,000 different silicone products supplied in over 100 countries worldwide. Its strengths are fast shipping, flexible combination of different types and quantities of products, and a wide, readily available product range.
Silicone Scientists Honored
The first WACKER SILICONE AWARD was presented. To date, this prize ranks among the world’s most prestigious awards in organosilicon chemistry. It was first awarded to Prof. Peter Jutzi and Prof. Robert Auner.
Expansion of the Biological Wastewater Treatment Plant in Burghausen
Designed for a capacity of up to 300,000 inhabitants, the plant now also treats wastewater from Burghausen and neighboring communities in Austria.
Entry into Asian Markets
Founding of Wacker Chemicals East Asia Ltd., Tokyo, Japan. A counterpart in Singapore was established a year later.
WACKER Silicon Conquers Space
Research in zero gravity: semiconductor experiments with silicon were conducted for WACKER and Chemitronic during the Spacelab mission.
WACKER Silicone Rubber Goes Liquid
Following the launch of WACKER’s first RTV (room-temperature-vulcanizing) and HTV (high-temperature-vulcanizing) grades on the market in the early 1950s and their constant enhancement, a new class emerged: LSR (liquid silicone rubber) products were introduced to the market.
The Birth of Siltronic
Wacker Siltronic Corporation was founded in Portland, Oregon, USA, for the manufacture and sales of semiconductor raw materials. The name Siltronic was used here for the first time.
A Dedicated Environmental Protection Department Established at the Burghausen Plant
The new department comprising Emissions Control, Wastewater Management and Residual Waste Management initiated the construction of a biological wastewater treatment plant.
Byproducts Become Bestsellers
HDK® was produced for the first time at the WACKER plant in Kempten. This pyrogenic silica was originally produced from the silanes that accumulated as byproducts of the Müller-Rochow synthesis (silanes and silicones) and the Siemens process (polycrystalline silicon). WACKER HDK® and its range of products are among the most successful WACKER products of all time. They are used in various applications such as silicone rubber, paints, coatings, laser toner, tooth paste and tomato ketchup.
The 1970s
Internationalization Begins
WACKER establishes new sales offices across Europe to bring its products closer to customers. Today, the company generates 80% of its sales outside Germany.
Founding of Wacker Chemitronic Gesellschaft für Elektronik-Grundstoffe mbH
This later became Siltronic. Two new full-scale production plants with distillation columns more than 50 meters high went into operation manufacturing hyperpure polysilicon and distilling the starting product trichlorosilane.
Transition from the Coal Age to Petrochemicals
Opening of the new ethylene-based vinyl acetate monomer plant. Calcium carbide was no longer needed in Burghausen. The eight 50-meter carbide silos – Burghausen plant landmarks – were repurposed to store mainly metallurgical-grade silicon used to produce silicones and hyperpure silicon.
Successful Launch into the North American Market
Founding of Wacker Chemicals Corporation WCC in New York, USA. WCC acquired Monosilicon, a company based in Los Angeles, USA, where hyperpure silicon rods produced using the crucible pulling process were cut into slices or wafers, as they are more commonly known. The term “wafer” had not yet been coined.
New Site, New Processes
At the new WACKER plant in Cologne, a facility based on the 2nd WACKER process was the first worldwide to start producing acetylaldehyde from ethylene on an industrial scale. This secured a cheap raw-material base for acetic acid and its derivatives in the VINNAPAS® range.
New facilities and buildings were erected, including a 19-meter-high crude silane column and a tank farm for pure and intermediate products in Burghausen. In the decade between 1957 and 1967, annual sales generated from silicon-based plastics increased almost fivefold to 37.8 million deutschmarks.
2nd WACKER Process
WACKER basic research scientists set up the production of acetylaldehyde and acetic acid using a new base raw material. Instead of using expensive acetylene made from calcium carbide, cheap ethylene from the petrochemical industry could be used to manufacture these products. Known as the 2nd WACKER process, this pioneering synthesis has been included in textbooks and has been licensed all around the world.
Instant Coffee Inspires a Bestseller Product
While enjoying a cup of Nescafé, Dr. Max Ivanovits came up with the idea of developing a water-free dispersible polymer powder from water-based dispersions. Powder production began in 1958; gradually, these powders revolutionized the construction industry and made WACKER the world leader in this field.
First Production of Hyperpure Silicon
Dr. Eduard Enk laid the foundation for WACKER’s semiconductor business. The first silicon rods were produced as early as 1955. Until 1961, several hyperpure silicon production plants went into operation.
Research Work into Silanes and Silicones Begins
Following his lecture on “Plastics Containing Silicon,” the young chemist Dr. Siegfried Nitzsche was hired on the spot. He later became the father of WACKER silicones. In 1949, Nitzsche and his colleagues successfully synthesized silane for the first time. Soon after, the first silane furnace was up and running.
Impending Closure
After the war ended, plant operations temporarily came to a halt as the Allies contemplated dismantling the company. The efforts of the WACKER management and workforce to prevent dismantlement were successful and the plant’s facilities gradually went back into operation. It was not until 1953 that the Allies relinquished control over WACKER as part of their “disentanglement” program, returning the company to its original owners.
Resistance to Destruction of the Plant
In the final days of the war, accountant Jakob Scheipel, senior factory foreman Ludwig Schön and foreman Josef Stegmair were sentenced to death in a drum-head trial and shot in the factory yard because they had attempted to prevent the National Socialists from destroying the plant.
“Foreign Workers” Replace Around a Third of the Core Workforce Called up for Military Service
A dark chapter for which WACKER takes responsibility: In 2000, WACKER became part of the “Foundation for Remembrance, Responsibility and the Future,” which made compensation payments to victims of forced labor and to foreign workers.
The Outbreak of World War II
Following the outbreak of the second World War, nearly all WACKER operations were deemed important for the war effort. This meant that production of base chemicals such as acetylaldehyde, acetic acid and chlorinated solvents continued unabated. Especially important during this time was the manufacture of high-quality metal alloys such as ferrochrome or ferrosilicon at the then WACKER plants in Mückenberg and Tschechnitz.
Patent Application for the Suspension Polymerization Process for PVC
Dr. Herbert Berg developed the process for manufacturing PVC. From 1935 until the business field was sold in 2000, WACKER PVC marketed under the VINNOL® brand turned into a growth engine that financed the development of modern production lines such as silicones and hyperpure silicon.
Start of VINNAPAS® Production
The managing director of the Consortium für elektrochemische Industrie, Willy O. Hermann, laid down the foundation for today’s WACKER POLYMERS business division back in the 1920s. Together with his team, he developed a process for producing vinyl acetate from ethylene and acetic acid on an industrial scale. In 1928, vinyl acetate went into production, followed two years later by polyvinyl acetate. Over the years, this would develop into the VINNAPAS® product line, ranging from adhesives in the wood industry to binders for construction applications, plastics, paper grades and woven fabric.
Production of Intermediate and End Products from Acetic Acid
A bestseller that was in production for almost 100 years. Acetic anhydride is used for the manufacture of pharmaceuticals and crease-resistant textile fibers. Production stopped in 1997.
Company Founder Alexander von Wacker, Recently Raised to the Non-Hereditary Aristocracy, Dies at the Age of 75.
Born: May 29, 1846
Died: April 6, 1922
WACKER Shellac Made from Plastic
The first plastic made from acetylaldehyde produced in Burghausen contributed to the ever-increasing vogue of gramophone records at that time.
Founding of Alzwerke GmbH, Construction and Commissioning of the Alz Canal
The 16-kilometer Alz Canal that joins the Alz and Salzach rivers is WACKER’s lifeline. The tamed hydropower of the Alz River generates cheap, sustainable electricity – to this day. The amount of electricity obtained per year is equivalent to the power consumed by a town with some 80,000 inhabitants.
Start of Acetone Production
With 450 employees, the factory began producing acetone from acetic acid in Burghausen in the middle of the First World War. Suddenly acetone became important for the war effort: it was used to make synthetic rubber for sealing submarine batteries. This was the starting point on the trajectory to becoming an international chemical company.
Construction of the Plant in Burghausen, Upper Bavaria
The first products manufactured in December 1916 were acetylaldehyde and acetic acid, which WACKER chemists developed by reacting acetylene (made from calcium carbide) with water. This entered the annals of the chemical industry as the 1st WACKER process for producing acetylaldehyde. These products were in the WACKER portfolio until 2012.
October 13, 1914
Establishment of Dr. Alexander Wacker, Gesellschaft für elektrochemische Industrie, AG
Having trained as a cloth dealer and salesman, Alexander Wacker had by this time already earned a reputation as a successful businessman, and together with Sigmund Schuckert, he had made Elektrizitäts AG (EAG) in Nuremberg into a leading business in the electricity industry.
A visionary – even at the age of 68. His new business model: to build an industrial plant, covering applications ranging from electrochemicals through to organic chemistry.
