WACKER SILICONES

With a range of over 3,000 silicone products, WACKER SILICONES ranks among the world’s largest manufacturers of silanes and silicones. We are also the market leader in key subsegments. Our product portfolio ranges from silanes through silicone fluids, emulsions, elastomers, sealants and resins to pyrogenic silicas. Thanks to their highly diverse properties, silicones offer virtually unlimited potential for intelligent, customized solutions in numerous sectors. Key application areas include engineering, electronics, chemicals, cosmetics, textiles and paper.

WACKER has manufactured HDK® pyrogenic silica since the 1970s. Due to our integrated production system with its statistical process control and highly efficient reactor dynamics, the pyrogenic silica we produce is exceptionally pure. Under the globally established brand name HDK®, WACKER offers an extensive product portfolio of hydrophilic and hydrophobic HDK® grades and HDK® dispersions. Furthermore, we offer our customers tailored service and practical support. Thus, we work closely with our customers and partners to develop commercial product innovations, and alternative forms of packaging and transport systems. HDK®products from WACKER are used in different industrial applications, where they improve processes and the end product in each case.

Hydrophilic HDK® is manufactured by the hydrolysis of volatile chlorosilanes in an oxyhydrogen flame. In chemical terms,it consists of highly pure amorphous silicon dioxide with the appearance of a fluffy white powder. Hydrophilic silica is wetted by water and can be dispersed in water.
