Several methods were developed to measure and identify the volatile species generated when PVC is heated to decomposition temperatures. PVC film compound containing various organotin stabilizers was processed under a range of typical conditions. The film samples were subjected to degradation temperatures of 210 to 230°C in both enclosed sampling systems (for optimum collection efficiency) and open systems that were designed to mimic working conditions. The collected samples were analyzed for amounts of hydrogen chloride, organotin compounds and organics in general. Variables such as type of stabilizer, degradation time and temperature, and sample thickness and fusion time were studied.
