Sodium Antimonate

Introduction

Sodium antimonate which also known as sodium pyroantimonate, is an inorganic salt compound of antimony, a white fine crystalline powder, mainly used as a fining agent or degasser in photovoltaic solar glass, display tube glassglass fiber, gemstone glass, high-grade glass tableware, leather manufacturing, etc.HS code 2841900090.

Main Applications

Sodium pyroantimonate is primarily used as a clarifier and defoamer for photovoltaic solar glass and kinescope glass for black and white and color display screens. It is also used as a clarifier and defoamer for high-end glass such as fiberglass, gemstone glass, and high-end glassware. It is also widely used as a flame retardant in engineering thermoplastics and rubber, such as flame-retardant electronic device casings, flame-retardant vehicle interiors, and flame-retardant electrical wiring. It is also used as a flame retardant in textiles, plastics, and building materials. It is widely used internationally as a clarifier to replace antimony oxide. It is widely used internationally as a flame-retardant alternative to antimony oxide. Scientific experiments and production have proven its superior technical performance. It exhibits superior flame retardancy in all polymers, and lower light-blocking properties and tinting strength in saturated polyesters and engineering thermoplastics. Its low reactivity is an advantage in sensitive polymers such as PET, where commonly used antimony oxide flame retardants are prone to depolymerization during handling.
