  Loading the traditional BFR/AO flame retardant system in ABS resulted in the expected V-0 rating and a high LOI value of 30%. In the literature [7][8] [9], this very efficient flame retardancy is. This study explores for the first time the synergistic fire retardant action of natural hydrated calcium borate, namely the mineral colemanite, which partially replaces antimony oxide in brominated flame retardant high-impact polystyrene compounds. Various antimony oxide to hydrated calcium borate ratios were employed keeping the brominated. Fire retardant polymer compositions according to cl wherein said synergist is antimony oxide. Fire retardant polymer compositions according to claim 2, wherein the comonomer with N-tribromophenylmaleimide is selected from the group consisting of acrylonitrile, styrene and vinyl chloride. P.J. Wakelyn, in Advances in Fire Retardant Materials, Risk reduction strategies for decabromodiphenyl ether. A technical assessment of flame retardant alternatives to decaBDE/ antimony oxide, the preferred flame resistant system available for furniture textile applications, was performed for the Swedish Chemicals Inspectorate. 55 This assessment suggested that intumescent .

— Antimony oxide is usually used at 1/4 to 1/3 the level of the chlorinated paraffins. Some formulas use higher levels of antimony but tests have shown this extra Sb2O3 adds little to the overall flame resistance. It should be noted that antimony oxide by itself has no value as a flame retarder. Theremust be halogens present for Sb2O3 to work. Gredmann Group.Gold Sun Technology is the leadingprovider of Antimony Trioxide in the global flame-retardant market. Gredmann Group ‧ Gold Sun Technology offers the most popular flame retardant (FR) relevant additive materials used in various kinds of plastic such as PVC, ABS, HIPS, PS, PP & Rubber, Paint, Paper Industries.   Zinc Borate is used as a flame retardant and smoke suppressant for a wide range of plastics, rubber, paper and textiles. It can replace antimony oxide as a synergist in plastics and rubber to enchance the activity of primary flame retardants by stepwise releasing the radicals. Is is also used in paints, adhesives, pigments and ceramic industries. Flame Retardant Synergist - Antimony Trioxide (Timonox) Low particle size, less impurity levels, used as synergist with brominated flame retardents in polyolefin cable applications Packing: 25 kgs Flame Retardent (Non Halogenated) - Reofos 50 Cost effective, flame retardant plasticizer Packing: kgs drum Smoke Suppresant - Zinc Borate -

Abstract. This category of flame retardants contains the two major additive flame retardants in use today — aluminium trihydroxide, A1(OH) 3 and antimony trioxide, Sb 2 O broad discussion is best separated into two parts.   A.M. Emsley, G.C. Stevens, in Advances in Fire Retardant Materials, Antimony trioxide. Antimony trioxide (ATO) is commonly used as a co-synergist with halogenated flame retardants to enhance their effectiveness. Recent comprehensive genotoxicity studies and a critical review by the European Commission have indicated that, contrary to the indications of earlier less well . 1. Calcium Borate is used as Flame retardant synergist in PVC, PP, Rubber and other plastics. It can be used against zinc borate to overcome thermal stability issues and its low density helps to reduce specific gravity of compound. It can also be used to replace Antimony tri oxide substantially (In PVC, PP) or . Additive vs Reactive Flame Retardants There are several chemical classes of flame retardants used with polymers including Brominates FR's, Organo Phosphorus FR's, Melamine-based FR's, Metal Hydroxide FR's, etc. Apart from these chemical classes, there are other flame retardants that can be incorporated into a polymer. They may act as additive and reactive flame retardants.
