Degradation of Rubber

The resistance to oxidative degradation depends on many factors, including chemical composition, molecular weight, crosslink density, and type of cross-links. Diene elastomers that have electron-donating groups attached to the diene are usually the least stable rubbers (NR, IR), i.e. they have poor heat, ozone and UV resistance, whereas elastomers with a low nuer of double bonds (HNBR, IIR
