Environmental regulations have now fostered two trends dominating flexible PVC compounding. These consist of the elimination of heavy metals and providing modified compositions that minimize disposal problems. The objectionable metals are lead and cadmium. In the U.S., lead stabilizers have been used predominately in wire and cable and roofing applications. Cadmium‐based stabilizers dominated all other areas of flexible PVC compositions except those applications requiring nontoxic components. The problems and achievements encountered in effecting compliance with the need to replace lead and cadmium usage in PVC compositions are discussed and suggested formulation types are provided.
