Application of High quality Silicon dioxide/Sio2 White Powder CAS No. 7631-86-9 with best price
Silica (SiO2) (RI: 1.48) is mined from deposits of diatomaceous soft chalk-like rock (keiselghur). This is an important group of extender pigments, which is used in a variety of particle sizes. They are used as a flatting agent to reduce gloss of clear coatings and to impart shear thinning flow properties to coatings. They are relatively expensive.
Silicon(IV) oxide, amorphous is used as carriers, processing aids, anti-caking and free-flow agents in animal feed. Defoamer applications such as paint, food, paper, textile and other industrial applications. Synthetic silicon dioxides are used as a rheology control agent in plastics. It is also used to manufacture adhesives, sealants and silicones.
Functionalized RAFT agent for controlled radical polymerization; especially suited for the polymerization of styrene; Azide group can be used to conjugate to a variety of alkyne-functionalized biomolecules. Chain Transfer Agent (CTA).
SDS mixture of sodium alkyl sulfates consisting chiefly of sodium lauryl sulfate
manufacture of glass, water glass, refractories, abrasives, ceramics, enamels; decolorizing and purifying oils, petroleum products, etc.; in scouring- and grinding-compounds, ferrosilicon, molds for castings; as anticaking and defoaming agent.
