Description

Previous work in Conoco labs, found that an antimony-based inorganic complex (41% antimony) was preferred to antimony oxide as the most cost effective flame retardant system in polyvinyl chloride wire and cable formulations. This current paper studies the effects on the physical and electrical properties comparing the antimony-based complex, antimony oxide, and no flame retardant in the general PVC formulation above. Heat stability, volume resistivity, tensile properties, and extrusion variations are examined.
