While antimony oxide has some disadvantages related to potential health issues, it is an outstanding flame retardant synergist. Years of research by many groups directed towards finding alternate synergists have found nothing that is as effective and as robust as antimony oxide.
Antimony oxide is a fine white powder, produced from the oxidation of antimony metal. It is used as a synergist with halogenated, predominately brominated, organic molecules to impart flame retardant properties to polymers. Halogenated compounds are inherently flame retardant and by themselves are capable of flame retarding polymers.
The use of antimony oxide decreases the amount of halogenated compound required for flame retardant performance. During fire, antimony oxide reacts with the halogenated material in the condensed phase, forming oxyhalides of antimony and antimony trihalide. As these moieties enter the gas phase, they act to quench radicals responsible for the propagation of the combustion process.
The use of masterbatches is the ideal way to incorporate antimony oxide into flame retardant formulations. At PMC Polymer Products, we encapsulate antimony oxide within a polymer masterbatch, resulting in ease of handling, less dust, and minimized exposure.
In addition to a wide range of Endura® flame retardant masterbatch applications, PMC Polymer Products has the unmatched expertise to work with you to develop custom formulations that meet your unique requirements.
We are focused on being responsive and providing the highest level of customer service. Whether it be a request for literature, advice on formulating a new FR compound or a rush shipment our goal is to be there for you.
