Munich/Charleston, December 14, 2016–Wacker Chemie AG will
build a new production plant for its HDK® brand of pyrogenic silica at
its Charleston site in the US state of Tennessee. The Munich-based
chemical company announced this today. The new facility, with an
annual capacity of about 13,000 metric tons, is anticipated to involve
capital expenditure of some US$150 million. Construction work will
start in the second quarter of next year, with completion planned for
the first half of 2019. This is expected to create some 50 new jobs at
the Charleston site. WACKER already produces hyperpure polysilicon
for the solar and semiconductor sectors in Charleston, with some 650
employees there.
 
“The additional capacities strengthen our market position as a leading
global producer of pyrogenic silica and help us to meet our customers’
growing demand,” said WACKER CEO Dr. Rudolf Staudigl.
 
“The new plant is the next logical step toward expanding Charleston
into a fully integrated silicon site in the world’s second-largest chemical
market,” he explained, underscoring the investment’s strategic
importance.
 
The new facility is a key addition to the Charleston site’s supply chain.
The main byproduct of polysilicon manufacturing is tetrachlorosilane,
which either has to be converted and fed back into the production
loop or can be used to create added value by being further processed
into HDK®. By integrating the polysilicon and HDK® production systems,
as already operated at its Burghausen and Nünchritz sites in
Germany, WACKER achieves maximum flexibility in the reprocessing
of tetrachlorosilane, avoids the need to dispose of waste products,
and thereby enhances the efficiency of the integrated production system
as a whole.
 
WACKER produces HDK® pyrogenic silica at Burghausen and
Nünchritz in Germany and Zhangjiagang in China. The Munich-based
chemical company is the world’s third-largest manufacturer in this
sector. Ultrapure amorphous silicon dioxide powder is used as a filler
in silicone elastomers and as a rheology-control additive in paints,
adhesives, unsaturated polyester resins and plastisols. It also serves
as a flow aid in the cosmetics, pharmaceutical and food-processing
industries.

process the resultant tetrachlorosilane byproduct from polysilicon
manufacturing into HDK® to create added value.
