Abstract
Extrudable anti-static polyvinyl chloride (PVC) compositions include a quaternary ammonium compound as an anti-static agent, and a barium-cadmium-zinc component as a stablizing agent. The barium-cadmium-zinc component has been found to be critically required in order for the compositions to be processable (e.g., via extrusion) while retaining their desired anti-static characteristics. Shaped articles (e.g., floor mats, door strippings, and the like) may be formed from the compositions of this invention, and use in environments where static-charge dissipation is desired (e.g., computer rooms, hospitals, and the like).
