Abstract: Polymer compositions containing a suitable polymer and a triazine metal phosphate compound are disclosed, and the triazine metal phosphate compound can have a d50 particle size from 0.1 to 45 μm and a BET surface area from 0.5 to 30 m2/g. The polymer compositions have improved moisture resistance and improved wet insulating properties as compared to polymer compositions that contain polymerized versions of the triazine metal phosphate compound. The polymer compositions can be utilized in a variety of end-uses, such as wire and cable applications.

Abstract: Processes for producing ammonium octamolybdate/metal hydroxide complexes include the steps of pre-contacting ammonium dimolybdate and a metal hydroxide, and then contacting molybdenum trioxide, to form the ammonium octamolybdate/metal hydroxide complexes. The resulting complexes contain the metal hydroxide and from 1 to 95 wt. % of ammonium octamolybdate, and generally, at least 80 wt. % of the ammonium octamolybdate in the complex is present in an orthorhombic crystalline form. These ammonium octamolybdate/metal hydroxide complexes can be used as smoke suppressants in polymer compositions, such as PVC-based and epoxy-based formulations.
