Major Sales Markets and Competitive Positions
(unaudited section)

WACKER’s three largest divisions rank among the top three suppliers worldwide.

Competitive Positions of WACKER’s Divisions

WACKER SILICONES is No. 2 globally and leads the market in Europe. In building-protection silicones, WACKER is the global market leader. Silicones are used in every major industry due to their versatile properties. The greatest growth potential is in Asia.

WACKER POLYMERS is the world’s largest producer of VAE dispersions and dispersible polymer powders. We are the only company in the market with a complete supply chain for dispersions and dispersible polymer powders in Europe, the Americas and Asia. We consider Asia to offer the largest growth potential.

WACKER BIOSOLUTIONS focuses on customer-specific solutions in sectors with strong growth, such as food ingredients, pharmaceutical actives and agrochemicals. We have achieved a strong market position in contract manufacturing of pharmaceutical proteins, plasmid DNA, live microbial products (LMPs) and vaccines based on bacteria, and we are expanding it. WACKER BIOSOLUTIONS is the global leader in cyclodextrins and vegetarian-grade cysteine.

WACKER POLYSILICON is one of the leading producers of hyperpure polysilicon worldwide. According to in-house analyses, the division is the global No. 1 for both polysilicon supplied to the semiconductor sector and n-type monocrystalline silicon used in highly efficient solar cells. Due to the development of the market environment in the global solar industry, the intensity of competition in this business remains high.

Cyclodextrins belong to the family of cyclic oligosaccharides (i.e. ring-shaped sugar molecules). They are able to encapsulate foreign substances such as fragrances and to release active ingredients at a controlled rate. WACKER BIOSOLUTIONS produces and markets cyclodextrins.
Cysteine is a sulfur-containing amino acid. It belongs to the non-essential amino acids, as it can be formed in the body. It is used, for example, as an additive in foods and cough mixtures. Cysteine and its derivatives are a business field at WACKER BIOSOLUTIONS.
Dispersible Polymer Powders
Created by drying dispersions in spray or disc dryers. VINNAPAS® polymer powders are recommended as binders in the construction industry, e.g. for tile adhesives, self-leveling compounds and repair mortars. They improve adhesion, cohesion, flexibility and flexural strength, as well as water-retention and processing properties.
Binary system in which one solid component is finely dispersed in another. VINNAPAS® dispersions are vinyl-acetate-based copolymers and terpolymers in liquid form. They are mainly used as binders in the construction industry, e.g. for grouts, plasters and primers.
A polymer is a large molecule made up of smaller molecular units (monomers). It contains between 10,000 and 100,000 monomers. Polymers can be long or ball-shaped.
Hyperpure polycrystalline silicon from WACKER POLYSILICON is used for manufacturing wafers for the electronics and solar industries. To produce it, metallurgical-grade silicon is converted into liquid trichlorosilane, highly distilled and deposited in hyperpure form at 1,000 degrees Celsius.
After oxygen, silicon is the most common element in the Earth’s crust. In nature, it occurs without exception in the form of compounds, chiefly silicon dioxide and silicates. Silicon is obtained through energy-intensive reaction of quartz sand with carbon and is the most important raw material in the electronics industry.
General term used to describe compounds of organic molecules and silicon. According to their areas of application, silicones can be classified as fluids, resins or rubber grades. Silicones are characterized by a myriad of outstanding properties. Typical areas of application include construction, the electrical and electronics industries, shipping and transportation, textiles and paper coatings.
