Amorphous Silica (Agrochemical Grade) Flowability Additive
CAS Number: 7631-86-9
Amorphous precipitated or fumed silica used in WP, WG, and DP pesticide formulations as an anti-caking agent, flowability additive, and active ingredient adsorbent carrier. Its ultra-high surface area and porous structure enable efficient adsorption of liquid active ingredients for conversion into free-flowing powders. Silica is particularly valuable in WP formulations containing liquid or waxy active ingredients that would otherwise cause caking and poor dispersibility.
