1. Precipitated Silica
Precipitated Silica is high purity, good flowability white granule or powder , with high adsorption and flow promotion properties，its two main functions are as carrier and anti-caking agent. As Carrier ，It is good carrier for various feed flavoring agents, vitamin，mold inhibitors, acid inhibitors, antioxidants, choline chloride, allicin and other products. As Anti Caking Agent，It is also used as anti-caking in fluffing agent, , premix, trace elements, vitamins and other products.
1.4 ELD 270PREMIUM
ELD-270P is in micro-pearl form, With very Good absorption capacity. and Homogeneous particle size and a narrow distribution. so it has excellent flowability and handling. therefore can Improvements both in terms of processing and product presentation.
