S17 Hydrophobic Silicon Flurry Powder 7631-86-9

  SKYSIL HYDROPHOBIC SILICA S17 1. Ultra-High Specific Surface Area (≥160 m²/g) – A Performance Multiplier • Defoamer: Increases adsorption capacity at the air-liquid interface, extending foam suppression time to ≥180 minutes, a 50% improvement over conventional products. • Lubricant: Enhances extreme pressure and anti-wear film formation, but requires a dispersant to prevent gelation. 2. Deeply Hydrophobic Treatment (Loss on Ignition ≤8.0%) • 8% Loss on Ignition corresponds to a 4-6 wt% dimethylsiloxane coating (TGA 400°C weight loss step), resulting in: Water contact angle >130°: Instant penetration of aqueous foam films (bubble break time ≤3 seconds). Improved oil resistance: Hydrophobicity retention >90% after 1000 hours of service in 150°C gear oil. 3. Low Tap Density (120-140 g/L) – A Process Revolution • Fluffy structure improves dry powder mixing uniformity (RSD <5%). • Reduces air bubble rate to 0.3% during high-speed dispersion in lubricants. 4. Strict Purity Contr…
