Fumed silica serves as a universal thickening agent


Fumed silica is a universal thickening agent and an anticaking agent (free-flow agent) in powders. Like silica gel, it serves as a desiccant. It is used in cosmetics for its light-diffusing properties. It is used as a light abrasive in products like toothpaste. Other uses include filler in silicone elastomer and viscosity adjustment in paints, coatings, printing inks, adhesives, and unsaturated polyester resins. It is also used in producing cat litter box fillers and as a core material in producing vacuum-insulated panels. Also known as pyrogenic silica because it is made in a flame, it consists of microscopic amorphous silica fused into branched, chainlike, three-dimensional secondary particles, which then agglomerate into tertiary particles. The resulting powder has an extremely low bulk density and high surface area. Its three-dimensional structure results in viscosity-increasing, thixotropic behavior when used as a thickener or reinforcing filler. Due to the material's structure and low bulk density, the customer had been experiencing blinding of filters in vacuum units and motors overheating, causing the branches to shut down.BVC was able to address this issue by using our IV40 industrial vacuum cleaner. The IV40 offers excellent levels of filtration and protection due to its superior filtration system. The product is first collected into a microporous bag. The filter bag with a large surface area provides secondary filtration, and finally, the H14 HEPA filter contains 99.995% of particles at the MPPS (Most Penetrating Particle Size). This construction ensures the product stays in the vacuum while the airflow required by the motor is protected to reduce the chance of the motor overheating significantly. After one year, the vacuums were working so well that a further order was placed to extend the use of the voids throughout the entire factory complex.
