10 Questions You Should to Know about hydrophilic fumed silica

Will different grades of Hydrophilic fumed silica affect the viscosity of silicone oil?

Hebei Silicon Research Electronic Materials Co., L contains other products and information you need, so please check it out.

HIFULL fumed silica produces 7 grades of hydrophilic fumed silica, and they have different specific surface areas. Today we will see their effects on the viscosity of silicone oil.

Here are four samples of silicone oil: Add eight percent of HIFULL HL-150, HIFULL HL-200, HIFULL HL-300 and HIFULL HL-380 into silicone oil samples separately

• Disperse each sample for five minutes by one thousand revolutions per minute in the high-speed disperser

• Then increase to two thousand revolutions per minute for 10 minutes

• Use Brookfield viscometer to measure after fully disperse

• The results show that the higher specific surface area of hydrophilic fumed silica leads to a higher viscosity of silicone oil

Due to the differences in manufacturing process, and product properties of silicone oil, if you have any problem in grade-choosing of hydrophilic fumed silica, feel free to contact &#;

Pyrohydrolysi & Trichloromethylsilane

If you are looking for more details, kindly visit silica dispersant.

Fumed silica is synthesized by the pyrohydrolysis of silicon tetrachloride or trichloromethylsilane in the flame of hydrogen and oxygen. Our main raw material is silicon tetrachloride, and the secondary is trichloromethylsilane.

Hydrophilic Fumed Silica SiO2:

HL-150 / HL-200 / HL-300 / HL-380 / HL-150W / HL-200W

Hydrophobic Fumed Silica SiO2:

DDS Treated &#; HB-151/ HB-152 ;
PDMS Treated &#; HB-139 ;
HMDS Treated &#; HB-132 / HB-135 / HB-612/ HB-615 / HB-620 / HB-630.

Price is based on the actual grade.

When the price of raw material fluctuates, we may adjust the price accordingly, please enquire before placing orders. Our : . Cell : +

When fumed silica is used as filler or additives, it helps in thickening, reinforcement, transparency, free-flow, thixotropic performance, dielectric properties, anti-settling, heat insulation, and anti-sagging. For example, for powder products, HIFULL fumed silica is used as an anti-caking agent; for liquid products, HIFULL fumed silica is used as an anti-settling agent or suspending agent.

Quality Stabilization: we are the earliest fumed silica manufacturers with independent R&D in China, which guarantees our product stabilization.

Largest Manufacturer: Our annual output of fumed silica is about 12,000 tons.

Strong R&D Team: Besides our own R&D institute and application& technology department, we&#;ve to build a research center with Sichuan University and Wuhan University, both are top-tier universities in China.

Leading Authority: We have already been the influential enterprise in the silicon industry in China. Doctor Wang Yuelin, the actual controller of Hifull, is the leader of the Sino-Germany project ISO-3 << Fumed Silica for Silicon Rubber>> and he is granted the Outstanding Contribution Award by the committee.
