47 Table 2.3 Tensile properties of FC 2260 nanocomposites a. Ultimate tensile strength of each formulation was used to characterize tensile strength 2.4.5 Thermal Stability Fluoroelastomers in general show good thermal stability and their degradation temperatures are over 400 o C (Wang, et al. 2009; Maiti, et al. 2008). However, the applications in some special fields such as aerospace and energy related industries demand higher degradation temperatures. Effects of nanoclays on fluoroelastomer degradation temperature were investigated by M. Maiti et al. (2008). It was shown that the presence of unmodified nanoclays increased the degradation temperatures of FKM due to polymer-filler interaction, exfoliation, uniform dispersion and high thermal stability of nanoclays (Maiti, et al. 2008). The temperature at which 5% sample weight

Unformatted text preview: loss occurs (T 5% ) is considered as the degradation onset temperature. The temperature at which the highest weight loss rate occurs is set as the degradation temperature (T max ).
