文摘

Pyrolysis of flexible and viscoelastic memory foams was performed. At 350-450 °C, diisocyanates are formed (around 0.1 μg/gsample). At 850 °C, the emission factors of ICA and PHI 1 and 0.01 μg/gsample, respectively. Isocyanate profiles observed agree with kinetic models proposed previously. Six new aminoisocyanates have been found in the evolved gases from FPUF pyrolysis.
