Recent introduction of non‐lead stabilizer systems to the wire and cable industry have shown a rising interest in these new products. Based on new regulations on the usage of lead stabilizers and the difficulties of disposing of vinyl containing lead in regular landfills, the interest to replace these products is in fact very high. The objective of this paper is to show what non‐lead systems are currently available and where their strengths and weaknesses are. Test results of laboratory studies are presented comparing environmentally and physiologically acceptable Ca/Zn, Mg/Zn, and Ca/Al/Zn stabilizer systems to conventional lead compounds in typical wire and cable formulations. In addition, data are presented on products that are already in use commercially.
