Zinc stannates, hydroxystannates

Zinc hydroxystannate and zinc stannate were synthesised at I.T.R.I. according to previously reported procedures (11,12)... [Pg.190]

Antimony trioxide, 8-stannic acid (hydrous tin(IV) oxide), zinc hydroxystannate, and zinc stannate were incorporated into the commercial brominated polyester resin at levels of 1,2,5 and 10% by weight. No processing problems were encountered and the samples cured satisfactorily to give rigid, opaque strips. [Pg.193]

Zinc hydroxystannate and zinc stannate are very effective flame-retardant synergists when incorporated at levels of 1-10% into... [Pg.207]

Inorganic tin compounds, in particular, zinc hydroxystannate and zinc stannate, are effective fire retardants in a number of polymer systems. They appear to have advantages over certain existing commercial additives, namely ... [Pg.209]

Zinc borate is also an effective SS in combination with phosphate ester plasticiser (130). The combination of ammonium octamolybdate and zinc stannate is also beneficial (435). It has been shown that ATH and MDH functional fillers coated with zinc hydroxystannate give significantly increased combustion resistance and lower levels of smoke evolution (386). Copper (I) complexes have been suggested as smoke suppressants (241). Copper oxides have also been investigated with positive results (60). [Pg.22]

By far the most important tin-based fire retardants are the zinc stannates - zinc hydroxystannate (ZHS) and its anhydrous analog, zinc stannate (ZS). Originally developed at ITRI during the mid-1980s, these additives are now being marketed worldwide as non-toxic flame retardants and smoke suppressants for use in a wide range of polymeric materials. ...

In polyolefins and epoxy resins melamine octamolybdate reduces the smoke development during the process of carbrniization of aromatic compounds. Other known smoke inhibitors are zinc borate, zinc stannate, and zinc hydroxystannate. [Pg.113]

Work in Poland has shown that zinc stannate and zinc hydroxystannate are the most efficient ignition and smoke retardants for GRP laminates, with antimony trioxide also being a good smoke suppressant. This appeared to be irrespective of the presence of other flame retardant additives. The resin systems also contained halogen additive or retardant components on the polyester backbone. [Pg.76]

Interest in tin compoimds as flame retardants for plastics has grown over the past 15 years. More than a dozen substances have been tried with some success, but only three of them, namely zinc hydroxystannate, zinc stannate and zinc oxide, are currently important. They all have low toxicity. Zinc stannate is preferred for use in polymers processed at temperatures over... [Pg.58]

Stannates. Zinc stannate [12036-37-2], Alcan s FLAMTARD S, and zinc hydroxystannate [12027-96-2], FLAMTARD HS, are both white water-insoluble powders useful as smoke suppressants in PVC. They can partly replace antimony oxide as flame-retardant synergists in halogen-containing flame-retardant formulations, with reduced smoke (16,17). [Pg.3196]
