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

RETRACTED ARTICLE: Pyrolysis study of waterborne polyurethane

“…Pyrolysis mechanisms and characterization of polyurethane polymers have been studied by others. Rotival et al [15] and Coutinho et al [16] evaluated the thermal degradation of polyurethanes by using a thermogravimetric (TG) analysis. Font et al [17] and Herrera et al [18] used TG and GC/MS to study the thermal decomposition of polyurethanes; they also proposed some principal degradation routs for the studied polyurethanes.…”

Yield and Composition of Gases and Oils/Waxes from the Feedstock Recycling of Waste Plastic

“…Thermogravimetric decomposition studies of polyurethane where pyrolysis takes place in a fixed bed of sample have been shown to produce mainly carbon dioxide and carbon monoxide [34]. It has been suggested that the carbon dioxide is produced by the breaking of the urethane bond and that degradation begins at around 250 • C [35].…”

Thermal degradation of polyurethane based on IPDI

“…The literature reports many experiments performed to investigate the thermal degradation of polyurethanes. Font et al [3] and Rotival et al [4] used thermogravimetric (TG) analysis to study the thermal decomposition of a polyurethane adhesive. Lattimer et al studied pyrolysis products from a segmented polyurethane by MALDI-MS in the temperature range of 250-325 8C [5].…”
