Sodium antimonate trihydrate

Introduction

Sodium metaantimonate (Na3O4Sb) is an excellent wear-resistant and flame-retardant agent, with excellent conductivity enhancement. It is primarily used in the manufacture of plastic parts for high-speed rail, aircraft, aviation, and other applications, as well as in the production of optical fiber materials, rubber products, paint products, and textiles.

Main Applications

Sodium antimonate can be used as a clarifier in cathode ray tubes, optical glass, and ultra-clear solar glass. also as a flame retardant for engineering plastics, textiles, and plastic products.
