Chemical Properties & Specifications
Antimony pentoxide is commonly used in conjunction with halogenated flame retardants to improve their efficacy in materials such as textiles, plastics, paper, and rubber.
It acts as a catalyst in the production of polyethylene terephthalate (PET), a widely used polyester in the textile and packaging industries.
Serves as a precursor in the synthesis of other antimony compounds, including antimony trioxide, which is used in various applications such as flame retardants and catalysts.
