replacement of antimony oxide in flame retardant formulations. The concept applies to many polymer systems and is based on the following convincing evidence. Notice Although the data listed are typical, they are not production specifications. To obtain exact production specifications, contact Rio Tinto.
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 particlesize range imparts the whitest color and highest opacity.
AntimonyIII Oxide or Antimony Trioxide is a highly insoluble thermally stable Antimony source suitable for glass, optic and ceramic applications. AntimonyIII Oxide is also available in pellets, pieces, powder, sputtering targets, tablets, and nanopowder from American Elements39 nanoscale production facilities.
DynaSil uniquely allows traditional halogen and nonhalogen flame retardants to work more effectively. A slight addition of DynaSil allows for reduction in heat release rate, a decrease in smoke generation, elimination or minimization of traditional hazardous flame retarding chemistries, improvements in processing and greater elongation of highly loaded compounds.

BrightSun antimony oxide aids in the formation of char on the substrate, which prevents the release of volatile gases. The char acts as a barrier between the substrate and the vapor phase, decreasing the oxygen available to the substrate. In plastics, antimony oxide also promotes crosslinking to create a more stable thermoset polymer and
At current market prices, partial replacement of antimony oxide with Kemgard can reduce flameretardant costs by 2050, Simpson says. The Kemgard family includes grades 911A and 425 molybdenumcalciumzinc complexes for PVC plastisols, wirecable coatings, wall coverings, and calendered films.
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 51 or higher 4. FR Ingredients 51 52 ATH 50 68 MDH 20 0
9.4.1 Synthesis of Antimony Oxide Glass NCs. Our preliminary investigation suggests that antimony trioxide Sb 2 O 3 based glass having composition mol KBS is one of the best dielectric hosts to study nanometalenhanced luminescence of RE 3 ions 108.
Antimony oxide is used as an opacifier in porcelain enamel mainly leadless but it has been replaced to an extent by titania and ceramic glazes. However it can give a yellowish color if the glaze contains lead, due to the precipitation of yellow lead antimonate known as Naples yellow.
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 trioxide is an industrial chemical and also occurs naturally in the environment. How is it used In Canada, antimony trioxide is primarily used in combination with other compounds to provide flame retardant properties. Flame retardants used in household items such as mattress covers, furniture and carpets may contain antimony trioxide.
Excerpt from A Thermal Study of Boric AcidSilica Mixtures, And, the Replacement of Tin Oxide by Antimony Oxide in Enamels for Cast Iron The two extremes of a series, now in a powdered form, were weighed out in the proper proportions to form the inter Mediate enamels. These were now mixed by rubbing 5 or 6 times through a 60 mesh sieve.
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. It alos acts as an anti fungal agent and as a soil amendment to improve the vigor of plants.
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
ICL Innovation seeks a cost effective synergist as an alternative to Antimony Trioxide to deliver halogen in the gas phase from plastic composites during combustion Background As the field of flame retardants evolves, so is the need for better and more cost effective synergists.
AntimonyIII oxide is an amphoteric oxide, it dissolves in aqueous sodium hydroxide solution to give the metaantimonite NaSbO 2, which can be isolated as the trihydrate. AntimonyIII oxide also dissolves in concentrated mineral acids to give the corresponding salts, which hydrolyzes upon dilution with water.
