Title: Comparison of Heating Behavior of Expandable Styrene Polymers Containing Graphite and Normal Expandable Styrene Polymers Authors: Li Yueming Venue: Gōsei jushi Year: 2012 Canonical: openalex:https://openalex.org/W2370441666 URL: https://openalex.org/W2370441666 Collector: openalex OA: false ABSTRACT The mass loss and pyrolytic deformation of graphite-embedded polystyrene(GEPS) and normal expandable polystyrene(EPS) foams were investigated by thermogravity analyzer and stereo pyroscope.As seen from the thermogravity curves,both EPS and GEPS foams presented two obvious stages of mass loss,and the high-temperature stage gave the main contribution of the total mass loss.Besides,it was found that the pyrolytic point θi2 of GEPS reached to 382 ℃,significantly higher than that of EPS(236.0 ℃).Meanwhile,the maximan pyrolytic rate θmax2 reached to 415.2 ℃,also obviously exceeded over that of EPS(263.7 ℃).The pyroscope observation revealed that GEPS foams showed off the deformation at 128 ℃ while began to melt with fluxibily at 260 ℃,much higher over EPS foams.
