Macro-pored Micro-spherical Silica Gel

CAS No.: 7631-86-9  |  High-Performance Dual-Grade Solutions (Industrial 50-120 Mesh & Cosmetic 100-200 Mesh)

CAS No.: 7631-86-9

Engineered Micro-Porosity for Multi-Industry Excellence

Macro-pored micro-spherical silica gel appears as white, transparent or translucent spherical grains featuring a uniform internal micro-porous structure, high mechanical strength, and exceptional thermal stability.

By precisely controlling particle size fractionation during manufacturing, we successfully expand this material from heavy industrial catalyst carriers (50-120 mesh) into high-purity, ultra-smooth micro-spheres tailored for luxury cosmetic formulations (100-200 mesh).

General Parameters

  • Appearance White Translucent Sphere
  • Pore Diameter 8.0 - 12.0 nm
  • Specific Surface Area 300 - 600 m^2/g
  • Pore Volume 0.8 - 1.1 mL/g
  • Thermal Stability Excellent (Up to 500°C+)

Dual-Purpose Matrix: Industrial Power & Cosmetic Elegance

Designed across specialized mesh cuts to serve demanding chemical synthesis and refined personal care applications.

Industrial Grade (Typical: 50-120 Mesh)

Heavy Industrial Synthesis & Catalyst Support

Built for rigorous chemical environments. Its high mechanical strength and macro-pored structure ensure long-term stability under severe thermal and pressure conditions in large-scale synthesis plants.

  • Key Applications: Melamine, phthalic anhydride, maleic anhydride, cis-butadiene rubber, and acrylonitrile production.
  • Petrochemical Refining: Selective removal of aromatic hydrocarbons and multi-valent harmful elements via ion exchange.
  • Standard Packaging: 20kg compound bag (Custom bulk options available).
