Antimony Trioxide (Sb₂O₃)

Antimony Trioxide (Sb₂O₃) is a flame-retardant synergist for manufacturers using halogenated flame retardants in plastics and rubber. Revona Chemicals supplies it for applications that include cables, PVC and engineering plastics, as well as textiles and coatings. It is described as a fine, white, odourless powder.

Antimony Trioxide for plastics, rubber and cables

In plastics and rubber formulations, Antimony Trioxide is used alongside halogenated flame retardants to improve flame-retardant performance. Its role is synergistic: it is selected as part of a flame-retardant system rather than treated as a stand-alone replacement for the other components. The material is also used in textiles and coatings. Named application areas include cables, PVC and engineering plastics.

For procurement and formulation teams, the first selection question is whether the intended application uses a compatible halogenated flame-retardant system. Confirm that the material suits the polymer or coating formulation and the fire-safety requirements relevant to the finished product. Specific standards, performance results and formulation ratios are not provided here; request technical information for evaluation.

Processing and grade selection

The known physical description is a fine, white, odourless powder. Detailed processing behaviour, such as incorporation conditions or formulation limits, depends on the selected material and the application. No processing temperatures, dosage guidance or grade-specific properties are stated here. Consult the technical data sheet and assess the material in the intended formulation before setting production parameters.

When comparing a grade, consider the end-use application, the polymer or coating system, the halogenated flame retardant with which it will be used, and the requirements for the finished product. Ask Revona Chemicals which grade information is available for your application. Confirm any relevant material specifications and processing guidance from the applicable technical documentation rather than assuming they are the same across grades.

Technical data sheets and samples for Antimony Trioxide

Revona Chemicals provides technical data sheets and samples on request. To support a product enquiry, share the intended application and material system, including whether the use is in plastics, rubber, textiles or coatings. For cable, PVC or engineering-plastics applications, include that detail so the enquiry can be directed appropriately. You may also request available grade information for review by procurement or R&D.

Use the requested documentation to check whether the offered material matches your formulation and internal requirements. If you need to evaluate the synergist in a specific compound or coating, request a sample and agree the assessment criteria with your technical team. Quotations are also available on request; no published price information is provided on this page.
