Product Description

Type A Desiccant  Fine-pored White Silica Gel


Fine-pored white silica gel includes fine-pored spherical silica gel and fine-pored lumpy silica gel, which are transparent or semitransparent glasslike in appearance. 

Product Features
*  Average pore diameter: 2. 0-3.0nm
*  Specific surface: 650-800m2/g,
*  Pore volume: 0.35-0.45ml/g
*  Specific heat: 0.92KJ/kg. ºC
*  Heat conductivity: 0.63KJ/m. Hr. ºC
*  Fine-pored silica gel is also called Type-A silica gel. 

Application
The gel is mainly used for desiccation and moisture absorption, and as catalyst carrier, adsorbent, separating agent and pressure-swing absorber as well.
