What is different between Silica Sol (Colloidal Silica) VS Silica Slurry (Silica Aqueous Dispersion)

Silica sol (colloidal silica) and silica slurry (silica aqueous dispersion) are both products made from silica powder. However, they differ due to their processing technology and application purposes. Below We will analyze the differences between the two from different dimensions. 1. Definition Differences Item Silica Sol (Colloidal Silica) Silica Slurry (Silica Aqueous Dispersion)Core Definition A stable dispersion system of nano-sized silica particles uniformly distributed in water, usually with electrostatic stabilization. Suspension of fine silica powder dispersed in water, forming a slurry.Particle Size 5–100 nm (commonly 10–30 [...]

How to Choose the Right Rutile Titanium Dioxide for PVC Applications

Introduction A few years ago, I received a frustrated call from a customer. Their newly installed PVC window frames had started chalking and fading within two years. The PVC wasn’t the real problem—it was the titanium dioxide they used. The supplier had offered a cheaper anatase grade, and while it saved a few dollars upfront, the long-term cost in replacements and reputation was much higher. That incident taught me something important: choosing the right rutile titanium dioxide (TiO₂) is not just [...]
