ShengdaTech Inc. SDTH, a manufacturer of nano-precipitated calcium carbonate (NPCC) and coal-based chemical products in China, has successfully started production and shipment of products from its three new stainless steel NPCC lines with an annual capacity of 60,000MT NPCC at the Xiangyang City factory in Shaanxi Province. The new stainless NPCC lines are expected to reach full production by August. The addition of this capacity has increased ShengdaTech’s total NPCC annual production to 190,000MT. The new lines employ the Company’s proprietary Membrane Dispersion Technology, which is patent protected and co-developed with Tsinghua University. ShengdaTech constructed the new lines using stainless steel equipment instead of carbon steel equipment, which was used in the previous lines. These stainless steel equipment lines are producing NPCC by employing ShengdaTech’s exclusive application-driven formulations, and are expected to position the Company to further increase the purity of the NPCC particles, a key competitive advantage.
