Antimony Trioxide

Antimony trioxide, also known as antimony oxide or Sb₂O₃, is the most widely produced compound of elemental antimony. The nations that produce the most antimony trioxide are China, South Africa, Bolivia, Russia, Tajikistan, and Kyrgyzstan. Typical applications for antimony trioxide include flame retardant synergist for use in plastics, rubber, paints, paper, textiles, and electronics; polyethylene terephthalate polymerization catalyst; a clarifying agent for glass; an opacifier for porcelain and enamel; and a white pigment for paint. When used as a flame retardant, antimony trioxide is often used in combination with halogenated compounds. Antimony trioxide is used as a synergist to enhance the activity of the halogenated flame retardant. In the absence of antimony trioxide about twice as much halogenated compound would be needed to reach the same level of flame retardancy.

Three grades of antimony trioxide

Jiefu is proud to offer three grades of antimony trioxide.

JIEFU KR grade antimony trioxide is suitable for almost all standard flame retardant and additive applications.

JIEFU Select is a higher purity grade of antimony trioxide compared to JIEFU KR. JIEFU Select can be used in flame retardant applications where lead levels are of concern, like in Europe to meet the requirements of the RoHS Directive. The Select grade is also used as a catalyst in PET production.

JIEFU's highest purity antimony trioxide product is JIEFU SP. JIEFU SP is suitable for highly lead and/or arsenic sensitive applications.
