HIFULL Fumed Silica Expert-- Company Profile
Hubei Huifu Nanomaterial Co., Ltd. is a joint-stock company established by the reform of Yichang Huifu Silicon Materials Co.,Ltd.We are National High-tech Enterprise, vice president unit of China Association of Fluorine and Silicon Industry (CAFSI), and National Innovative Incubation Base.
Huifu gets 72 technical patents. The core patents "Technology for the production of fumed silica using by-products from the polysilicon "and "A deacidification process and its equipment" won the China Patent Excellence Award. We are the only company that has won the honor in this industry.
We also lead in setting the domestic and international standard of fumed silica. As project director, doctor Wang Yuelin hosted and contributed to setting the international standard of ISO 18473-3:2018, it is the standardization for fumed silica used in silicon rubber. In China, doctor Wang Yuelin has been in charge of setting up and revising the project of GB/T20020 for fumed silica. Now we are in charge of formulating the ISO international standard "Test Method for Silicon Hydroxyl Content on Fumed
Silica Surface", leading the revision of the national standard "Nano Alumina", and participating in the formulation of the national standard "Nano Material Terminology".
