Organotin compounds have long been known in the PVC industry for their excellent performance properties in almost every application. Over the past several years, a wide variety of health and environmental studies have been conducted which demonstrate the safe use of these performance chemicals as PVC heat stabilizers. This paper introduces the “risk equation” and then applies this equation to the foreseeable exposure risks involved with the use of organotin stabilizers during PVC processing. Further, migration of organotin species from PVC end‐use articles is discussed with comparison to established long‐term no‐effect levels for these chemicals. The environmental fate of organotin compounds and their effects on some species of microorganisms is also addressed. The risk equation is used to fully evaluate all potential hazards to provide a fully informed risk assessment for the use of organotin stabilizers in PVC.
