ABSTRACT:
A flame resistant and smoke suppressed plasticized polyvinyl chloride polymer containing from about 20 to about 100 parts per hundred resin (phr) of a plasticizer comprising an ester-type primary plasticizer in combination with a controlled amount of a chlorinated paraffin or organic phosphate ester secondary plasticizer and an effective amount of a flame retardant and smoke suppressant agent comprising inorganic molybdenum compounds, such as molybdenum oxides and metal molybdates. In accordance with a preferred embodiment, the flame retardant and smoke suppressant agent further includes a controlled effective amount of antimony oxide in combination with the molybdenum compound imparting synergistic flame retardancy and smoke suppressing characteristics to the plasticized polyvinyl chloride resin formulation.
