PRODUCT DETAILS
1.Product Description
This feed grade silicon dioxide is a synthetic amorphous silica feed grade and a feed-grade synthetic silica, a synthetic, non-crystalline, high-purity silicon dioxide specially produced for animal nutrition. As an animal feed additive silica and a silica powder feed additive, it functions as an anti-caking agent and flow aid in powdered feed, improves the flowability of feed powders, prevents caking, and ensures uniform mixing and stable storage. It is a silicon dioxide E551 for animal feed, an ins 551 silica feed grade (E551 / INS 551) manufactured by the precipitation process, also known as feed grade white carbon black, amorphous silicon dioxide feed additive and non-crystalline silica feed additive. With CAS 7631-86-9, it is a feed-grade silica CAS 7631-86-9, a food compliant silica for animal feed, a high purity feed grade silica, an SiO2 powder for animal nutrition and a silicon dioxide powder for feed industry — a safe, food-compliant raw material trusted by premix, complete feed and pet food producers.
