Antimony(III) oxide has suspected carcinogenic potential for humans. Its TLV is 0.5 mg/m 3, as for most antimony compounds. No other human health hazards were identified for antimony(III) oxide, and no risks to human health and the environment were identified from the production and use of antimony trioxide in daily life.

Based on its Risk Profile developed ... Antimony trioxide and zinc borate are primarily ...
The term decaBDE alone refers to only decabromodiphenyl ether, the single "fully brominated" PBDE. DecaBDE is a flame retardant. The chemical "is always used in conjunction with antimony trioxide" in polymers, mainly in "high impact polystyrene (HIPS) which is used in …
Dicumene ( alternative of Antimony) is an environment friendly replacement for Antimony Tri-oxide (Sb2O3) and is commonly used as a Flame Retardant (FR) synergist for polypropylene and polystyrene, especially in expandable polystyrene (EPS). Chemical Name: 2,3-Dimethy-2,3-Diphenylbutane.
Zinc borate, molybdic oxide, zinc oxide, and magnesium oxide can be used in conjunction with antimony oxide to augment char formation and decrease smoke. Replacement of the antimony oxide to meet a smoke requirement compromises the flame retardance. See also Flame retardant mechanism of antimony trioxide

The information on this web page is provided to help you to work safely, but it is intended to be an overview of hazards, not a replacement for a full Material Safety Data Sheet (MSDS). MSDS forms can be downloaded from the web sites of many chemical suppliers. General
antimony oxide to achieve desirable smoke suppression performance while not only reducing costs, but also minimizing regulatory concerns over antimony oxide use. As compounders search for environmentally-friendly replacements for antimony oxide and halogenated additives, Kemgard flame retardants and smoke suppressants also work well
Antimony Oxide Glass NCs 221 ... strategies should be based on a solid understanding of what works and how effectively substitution can be a direct replacement. However, some of the 'risk reduction' measures proposed from the EU Risk Assessment Process appear to be based on 'avoidance' rather than sound science. For example, with ...
* Antimony Trioxide may damage the kidneys, liver and heart. IDENTIFICATION Antimony Trioxide is a white, odorless crystalline (sand-like) powder. It is used as a flame-proofing agent, in pigments and ceramics, to stain iron and copper, and to decolorize glass. REASON FOR CITATION * Antimony Trioxide is on the Hazardous Substance List

Based on current market prices for zinc borate at $1.00-1.29/lb, partial replacement of antimony oxide with zinc borate can result in a cost reduction of 25-40% of the total synergist package.
In many parts of the world, users are demanding the exclusion of antimony oxide from polymer formulations for health and safety reasons while still demanding comparable or lower smoke performance in these non-antimony formulations. Below is an application example using C-TECIN CTZHS and antimony oxide in the same unfilled PVC formulation.
While partial replacement of antimony oxide is justied by synergy with Firebrake ZB even at similar pricing for the two additives, Firebrake ZB has been a lower cost additive than antimony oxide in recent years, which strengthens the cost saving for partial replacement of antimony oxide …
Antimony trioxide has been used as a white pigment since ancient times. The pigmentation from antimony oxide in plastics can be controlled and adjusted by the judicious selection of a Sb 2 O 3 grade having a specific particle size. The product with the smallest particle size and the narrowest particle-size range imparts the whitest color and highest opacity.
Using a standard PVC plenum formulation DynaSil™ was evaluated as a total replacement of Antimony and compared looking at LOI and Physical properties. DynaSil is a 50% active concentrate. Adding 3% DynaSil as a one-to-one replacement of antimony, all flame retardant properties and mechanical properties are maintained. Replacing Antimony in PVC

Zinc borate, molybdic oxide, zinc oxide, and magnesium oxide can be used in conjunction with antimony oxide to augment char formation and decrease smoke. Replacement of the antimony oxide to meet a smoke requirement compromises the flame retardance. A relationship exists between particle size and tinting strength.
antimony oxide in PVC formulation significantly reduces flammability of the compound. Partial or complete replacement of antimony oxide with metal hydroxide without negative effect on compound flammability is possible, but it requires higher antimony to hydroxide ratio, such as 5:1 or higher .

To that end, the excellent aqueous durability performance of Sb-vanadium phosphate frits was maintained without Sb 2 O 3 by replacement of the antimony oxide by a combination of Fe 2 O 3 +TiO 2, along with a small addition of ZnO to maintain flow and glass transition temperature (T g).
Brominated flame retardants are used in a variety of applica-tions from electronic housings to printed circuit boards and electrical connectors to flexible and rigid polyurethane foam. ... Cost effective antimony oxide replacement for stringent rigid PVC applications.
Antimony oxide is restricted or excluded from some Eco Labels (some Blue Angel and EU Flower ecolabels) because of R 40-phrase or Class 3 carcinogen ... issues.
