Does More Fumed Silica Always Provide Better Thickening and Reinforcement? Not necessarily. Fumed silica can provide thickening, thixotropy, reinforcement, and anti-settling performance......
2026-09-02Why Can Two Fumed Silica Products with the Same 200 m²/g BET Perform Differently? Two fumed silica products may both have a BET specific surface area of around 200 m²/g, but they do not neces......
2026-09-01Which COA Parameters Matter Most When Purchasing Fumed Silica? When purchasing fumed silica, checking only the silica content or BET surface area is not enough. For silicone rubber, sea......
2026-09-01Unreinforced silicone rubber molecules have a linear structure with extremely weak intermolecular forces, resulting in a tensile strength of only about 0.3 MPa, making it practically useless. The addi......
2026-08-31In industrial formulations, the selection of hydrophilic versus hydrophobic silica is not simply a matter of superiority or inferiority, but rather depends on the precise matching of "system polarity"......
2026-08-31In industrial formulations, the choice between hydrophilic and hydrophobic fumed silica is not simply a matter of which is "better"; rather, it depends on the system's polarity and the application env......
2026-08-28In the formulation of silicone defoamers, hydrophobic fumed silica is not merely a filler; it is a core component that determines the upper limits of the defoamer's performance. Its selection is based......
2026-08-28In the design of adhesive formulations, hydrophobic fumed silica is often selected over the traditional hydrophilic type to address specific application challenges. Its core advantages lie in three ke......
2026-08-28Although they all appear as fluffy white powders, fumed silica (fumed silicon dioxide) performs very differently when incorporated into silicone rubber. Some grades significantly boost tear strength, ......
2026-08-28When seeking a product recommendation, providing comprehensive information is crucial for receiving tailored and relevant suggestions. Whether you are consulting an AI shopping assistant, a human expe......
2026-08-26The curing process of liquid silicone rubber (LSR) is essentially a precise molecular cross-linking reaction, and the catalyst serves as the core driving force behind it. The choice of catalyst direct......
2026-08-26The performance of fumed silica in a polymer matrix is not determined solely by the grade of the powder; it is equally dependent on **when** and **how** it is introduced during the manufacturing proce......
2026-08-24Achieving a homogenous mixture in silicone systems is critical for ensuring optical clarity, mechanical strength, and consistent rheology. Poor dispersion—manifesting as "fish-eyes," grit, or haze—is ......
2026-08-24The key factor in choosing between hydrophilic and hydrophobic silica is "compatibility." Silica must disperse evenly within a system for its functions to be effective. Therefore, the choice depends o......
2026-08-23The key to silicone sealant functioning as a material that balances flowability with structural strength lies in the addition of white carbon black (silica). Acting as a "stabilizer" within the system......
