JS-280E Precipitated Silica: Allows Powders to Flow Easily, Maintaining Lasting Quality
In industries such as food, pesticides, feed, and cosmetics, powder clumping, poor flowability, and short shelf life have long been core pain points for manufacturers. This is particularly true for high-fat powders such as non-dairy creamer, milk powder, seasonings, pesticide wettable powders (WP), and water-dispersible granules (WG). These products are particularly susceptible to clumping due to moisture absorption and oil exudation, severely impacting production efficiency and end-user experience.
Now, JS-280E, a highly absorbent precipitated silica, is offering exceptional performance, making it an ideal alternative to Evonik's Sipernat® 50S, bringing a revolutionary solution to the powder industry.
I. What is JS-280E?
JS-280E is a high-purity silica produced using an advanced precipitation process. It features a high specific surface area, high oil absorption, and ultrafine particle size. Its unique porous structure gives it exceptionally strong adsorption capacity, effectively absorbing moisture and oil from the powder surface, preventing interparticle adhesion and significantly improving powder flowability and stability.

% | Max.7.0 |
| Ignition loss 1000°c | - | 6.0 -8.0 |
| Apperance | - | Amorphous, Free Flowing White Appereance Powder |
II. Core Advantages: Why Choose JS-280E?
1. Superior Adsorption, Locking in Oil and Moisture
JS-280E rapidly absorbs free moisture and oil from the powder surface, forming a "dry barrier" that effectively prevents clumping and adhesion. It is particularly suitable for formulations high in fat, sugar, or those prone to moisture absorption.
2. Enhanced Flowability, Improved Production Efficiency
Adding a small amount of JS-280E (typically 0.5%–3%) significantly improves powder flowability, reduces bridging and clogging, and enhances automated packaging and metering efficiency, minimizing downtime.
3. Extended Shelf Life, Guaranteed Product Quality
By inhibiting moisture migration and oil oxidation, JS-280E helps powder products remain loose, dry, and stable during long-term storage, extending shelf life and reducing returns and waste.
4. High Concentration + Fine Particles, Perfectly Suited for Agrochemical Formulations
In the pesticide industry, JS-280E is an ideal carrier for wettable powders (WP) and water-dispersible granules (WG).** Its high adsorption capacity allows it to carry high concentrations of active ingredients while maintaining fine particles and excellent dispersibility, meeting the stringent suspension efficiency and wettability requirements of spray applications.
✅ Improves suspension efficiency by 10%–20%
✅ Reduces wetting time to less than 60 seconds
5. A cost-effective alternative to Sipernat® 50S
JS-280E comprehensively matches Evonik's Sipernat® 50S in key performance indicators such as oil absorption, particle size distribution, and improved flowability, but offers more flexible delivery cycles and a more competitive price, helping companies reduce costs and increase efficiency.
