Abstract:The thermal decomposition properties and products of three low ignition propensity (LIP) cigarette papers, a typical blended type and a typical flue-cured type tobaccos and the mixtures of LIP cigarette paper and the tobaccos were studied by thermogravimetry-infrared-gas chromatography-mass spectrometry technology for the first time. Surface physical morphologies of the papers were observed by electron microscope. The results showed that the amount of pores were lesser and the size also smaller after LIP material was applied, and the decomposition temperatures were also lower. The main decomposition products of all samples were similar observed by the infrared spectra. There was no obvious change in decomposition products when the LIP cigarette papers were combined with the blended type tobacco, while the dipentene was reduced when LIP cigarette paper was combined with the flue-cured type tobaccos, determined by the gas chromatography and the mass spectrometry.
