Our directors were invited to the relocation celebration of the Guangzhou branch of Chemours Chemical (Shanghai) Co., Ltd. Chemours, spun off from DuPont in July 2015 and listed on the New York Stock Exchange, runs three core businesses — titanium technologies, fluoroproducts and chemical solutions — and remains the source for the Teflon™ and Tefzel™ lines we distribute.
Senior managers from Chemours’ Ti-Pure™ business and from Yada Electronics (Dongguan), a maker of high-temperature wire, cable and connector harnesses, visited Ruihaifa (Shanghai) Polymer Materials Co., Ltd.
