A flame resistant and smoke suppressed plasticized polyvinyl chloride polymer containing from about 20 to about 80 parts per hundred resin (phr) of an ester-type plasticizer and an effective amount of a flame retardant and smoke suppressant agent comprising an inorganic molybdenum compound 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 an antimony compound such as antimony oxide in combination with the molybdenum compound imparting synergistic flame retardancy and smoke suppressing characteristics to the plasticized polyvinyl chloride resin formulation.

Ester-plasticized polyvinyl chloride resin composition containing

A method for recovering plastic from plastic insulated wire scrap involving separating the plastic from short segments of the wire by agitating the segments in a heated dry powder medium until the metal is released from the plastic insulation, separating the metal from the plastic insulation leaving at least 0.5% by weight of the powder intermixed with the plastic insulation.
