“…This also supports that double bond formation is not predominating. Now the breakage of chain carbon atoms can involve the scission of CeF bonds both in the side group as well as on the backbone [30]. These can involve the formation of volatiles like fluoroform (degradation of the side group) usually mixed with vinylidene fluoride fraction (scission of main chain).…”

ABSTRACT:The effect of electron beam irradiation on the properties of carbon black-, silica-, and clay-filled fluorocarbon rubber has been studied over a range of radiation doses, loadings, and nature of the fillers. Compared to the unfilled irradiated rubber, the tensile strength and modulus improve with a decrease in the particle size of the carbon black filler. Similar improvement in these properties is observed with an increase in both the radiation dose and the amount of the filler upto a certain level. The dynamic mechanical analysis reveal an increased glass transition temperature (T g ), a reduced value of the mechanical loss factor at T g . and an enhanced dynamic storage modulus for the filled samples. The results are explained with the help of sol-gel analysis and volume fraction of rubber. It is observed that higher reinforcement in the case of the filled vulcanizate is obtained by electron beam modification, as compared to that using the conventional curing system.

“…Thermal curing involves a long cure time, high -energy consumption, evolution of volatile toxic byproducts, and creates residual stresses in the material, whereas electron beam curing of rubber is a fast nonthermal process that utilizes highly energetic electrons at controlled doses for curing of variety of components for aerospace, automotive, and consumer applications [119] . Apart from crosslinking, electron beam radiation may also result in oxidation and degradation of a network structure [120] . The crosslinking effi ciency of a rubber under an electron beam depends on its molecular structure.…”
