Replacement of lead based stabilizers with lead free stabilizers-3 Until 2016, 80% of the world’s manufacturers were using lead stabilizers, the remaining 20% are used to stabilize PVC food packing, mineral water bottles and pharmaceutical containers. Despite many advantages, the toxicity of lead has brought a restriction to the use of lead based stabilizers in PVC articles. This restriction brought a revolutionary change in PVC processing. In…

Replacement of lead based stabilizers with lead free stabilizers-2 Besides Ca-Zn stabilizers, Organotin mercaptide based stabilizers are another choice. These are generally available in liquid form, but nowadays powder form is also available with some manufacturers. Organotin stabilizers are very popular for transparent applications and rigid applications in America. They offer outstanding color retention in plasticized and rigid PVC processing…

Replacement of lead based stabilizers with lead free stabilizers-1 Nathaniel Branden, a famous Canadian-American psychologist once said, “The first step toward change is awareness. The second step is acceptance.”Lead based stabilizers are being used from the very beginning to stabilize rigid PVC across the world. The decomposition temperature of PVC is much lower than its processing temperature. Thus, the processing of PVC requires heat stabi…
