With continuous exploration and innovation in the application functions and fields of fumed silica, Hubei Huifu Nanomaterial Co., Ltd.(HIFULL®) has achieved ongoing breakthroughs and results in the application of fumed silica nanopowder.
To date, HIFULL® offers 9 grades of hydrophilic fumed silica (HL-30/HL-50/HL-90/HL-150/HL-200/HL-260/HL-300/HL-380/HL-450) and 12 grades of hydrophobic fumed silica: 5 treated with hexamethyldisilazane(HMDS) (HB-132/HB-612/HB-615/HB-620/HB-630), 3 with polydimethylsiloxane(PDMS) (HB-139/HB-139B/HB-139C), 2 with dimethyldichlorosilane(DDS) (HB-151/HB-152), and 2 with special silanes (HB-701/HB-202N).
Among them, the low specific surface area hydrophilic fumed silica HL-30 and HL-50 are new grades launched by HIFULL®. Compared to previous fumed silica products, these additions fill the gaps in the high, medium, and low specific surface area product series, making product applications more precise and segmented.
As a hydrophilic fumed silica with a specific surface area of around 100m2/g, HL-90 features low specific surface area and easy dispersion. Its excellent dispersibility and stability make it widely used in fields such as chemical mechanical polishing and metal cutting fluids, serving as a superior polishing and grinding aid. Meanwhile, HL-260 and HL-450, which offer excellent reinforcement effects without affecting product transparency, are highly acclaimed in the liquid silicone rubber (LSR) field. Although HL-90, HL-260, and HL-450 demonstrate outstanding performance in these specific application areas, they can still function as raw material additives in other fields.
To further focus on the industry and professional quality, HIFULL® has coordinated its Application Technology R&D Center, Production Technology R&D Department, Quality Control Department, and Production Department. After years of effort and hundreds of breakthroughs, they have developed raw material additives specifically for applications in the food and pharmaceutical fields. Characterized by being colorless and odorless, highly safe, stable, high in purity, high in specific surface area, and highly active, this series of products is set to be released in 2024.
HIFULL® Food Additive-Silicon Dioxide is an excellent anti-caking agent, flow aid, and dispersion/grinding aid in powdered or granular foods. It effectively resolves issues of moisture absorption and caking in powdered or granular foods caused by environmental humidity, air, and compression during production, transportation, and storage, thereby improving the production efficiency of powdered foods and extending their shelf life.
HIFULL® Pharma Grade-Colloidal Silicon Dioxide is widely used in the pharmaceutical field as a flow aid, lubricant, excipient, and carrier. It plays a significant role in promoting drug disintegration and sustained release, and is extensively applied in drug manufacturing, drug controlled release, drug delivery, and drug absorption.
