Product Usage
Antimony trioxide is a widely used additive flame retardant, which is suitable for general flame retardant of polyethylene, polypropylene, polystyrene, polyvinyl chloride, polyester, epoxy resin, polyurethane and other plastics. When used alone, the flame retardant effect is low. When used together with phosphate esters, chlorinated compounds (such as chlorinated paraffins, polychlorinated biphenyls, and perchloroshiocyclodecane), and brominated compounds (such as hexabromobiphenyl and hexabromobenzene), the flame retardant effect is improved significantly.
