Gases emitted during thermal decomposition of a polypropylene film and a polyurethane adhesive

摘要: The thermal decomposition of a polypropylene film, polyurethane adhesive, as well coated with adhesive have been studied by thermogravimetric (TG) analysis, at heating rate 5°C minute air flow. During the analysis different steps which correspond to weight loss rates were obtained on curves. Gases collected between and then analyzed. results reported deal conversion carbon into oxides aldehydes—ketones, also that nitrogen hydrogen cyanide isocyanates. findings lead better understanding hazards risks toxic emissions may be generated gas formation following these materials.
