CAS: 14808-60-7

Technical Parameters:

Product Features

1. High purity, small particle size, uniform distribution, large specific surface area, high surface activity, high temperature resistance, low bulk density;

2. Excellent dispersibility, suspension stability, vibration liquefaction, good thixotropy, reinforcement, and thickening effects; improved hydrophilicity and lipophilicity after surface treatment;

3. Abundant unsaturated residual bonds and hydroxyl groups in various bonding states; high reactivity due to oxygen-deficient surface deviating from stable siloxane structure; low bulk density and easy dispersion;

4. High reflectivity to both ultraviolet and visible light: 70%~80% for short-wave UV (200~280nm), 80%~85% for mid-to-long-wave UV (280~400nm), over 85% for visible light (400~800nm), and over 70% for near-infrared (800~1350nm).

Potential Applications:

1. Rubber modification, sealant ceramic toughening, adhesive modification, functional fiber additives, plastic modification, anti-paint aging additives;

2. Ceramics, nano-ceramics, composite ceramic substrates;

3. Polymers: enhances thermal stability and anti-aging properties;

4. Flame retardant materials, coatings, high-grade grinding media, cosmetics, etc.;

5. Adding a small amount of nano-SiO2 to solution-polymerized styrene-butadiene rubber and chlorinated polyethylene improves toughness, strength, elongation, flex resistance, UV aging, and thermal aging resistance, matching or exceeding EPDM rubber;

6. Adding a small amount of nano-silica to traditional coatings improves suspension stability, thixotropy, anti-aging performance, and smoothness.

Perfectly Spherical Silica:

1. Light diffusion: excellent light diffusion when combined with PMMA, PS, PP, and other resins in light diffusion substrates or films;

2. Electronic adhesives, potting compounds;

3. Engineering plastics, films, transparent substrates, membrane fillers, hard coating fillers;

4. Special ceramics, electronic ceramics, ceramic membranes, dental materials;

5. Electronic inks: improves ink and pigment opacity, gloss, and film-forming properties;

6. High-end paints and coatings;

7. Polishing agents for polishing applications;

Packaging & Storage

1. Custom packaging upon customer request (<1kg; 50g~500g/bag or bottle);

2. Sample packaging (1kg/bag);

3. Standard packaging (8kg/bag; 10kg/bag; 20kg/bag; 25kg/bag).

Default packaging: sealed transparent PE bag/aluminum foil bag, with outer carton/paper drum/iron drum. Store sealed in a dry, cool environment after receipt. Avoid prolonged exposure to air to prevent moisture-induced agglomeration, which may affect dispersion and performance.
