Application
Synthetic Magnesium Silicate Adsorbent is white fine powder, amorphous, with vesicular structure and huge specific area, it is an amphoteric compound capable of adsorbing either acid or alkali metal catalyst. It is an efficient refining and purifying agent in the production of polyols for its excellent depicking, deodorizing, potassium ion adsorbing effects and function as filter medium.
