A new synergistic effect in the smoke suppression of plasticized poly(vinyl chloride) by mixed-metal Cu(II) oxides

A new synergistic effect in the smoke suppression of plasticized poly(vinyl chloride) by mixed-metal Cu(II) oxides

In a plasticized poly(vinyl chloride) formulation of a commercial type, various mixed‐metal oxides of Cu(II) were effective smoke suppressants when used alone and strongly synergistic for smoke suppression when they were combined. Particularly attractive for smoke suppression was a synergistic binar...

Description
Summary:In a plasticized poly(vinyl chloride) formulation of a commercial type, various mixed‐metal oxides of Cu(II) were effective smoke suppressants when used alone and strongly synergistic for smoke suppression when they were combined. Particularly attractive for smoke suppression was a synergistic binary blend of Cu 3 (MoO 4 ) 2 (OH) 2 and CuTi 3 O 7 , which was much more active for smoke reduction, in cone calorimetry trials, than the well‐known commercial additive, ammonium octamolybdate. In plasticized commercial‐type formulations, some mixed‐metal Cu(II) oxides and their blends were also highly effective for reducing heat evolution. Smoke performance was assessed according to ASTM‐E662 and ASTM‐E1354; total heat release was studied by pyrolysis‐combustion flow calorimetry. J. VINYL ADDIT.
