Abstract

Carbon nanotube (CNT)-, carbon black (CB)-filled fluoroelastomer (FE) and unfilled-fluoroelastomer were prepared (CNT/FE, CB/FE and fluoroelastomer). Their thermal gravimetric analysis in presence of air and under nitrogen flow was compared. Results show that in presence of air carbon nanotube improved the thermal properties of fluoroelastomer, resulting in higher amount of fluoroelastomer and char remaining after TGA runs in the temperatures range of 520-900 °C, relative to fluoroelastomer and CB/FE. Moreover in all fluoroelastomer samples at 900 °C most of the fluoroelastomer, char and carbon nanotube or carbon black burned, degraded and evaporated and therefore most mineral additives remained compared to nitrogen surroundings. In TGA runs for the aforementioned temperature range, the percentage of undegraded fluoroelastomer or char remained in the compounds is more for tests under nitrogen flow compared to tests in presence of air. Changing the environment from nitrogen to air is not effective on T_onset, T_{5 %}, T_{10 %} and T_{50 %}. Carbon nanotube does not affect these parameters of CNT/FE compared to CB/FE or fluoroelastomer.
