Abstract

Mechanical properties and thermal degradation characteristics of natural rubber compounds containing coconut oil were compared with that of a control compound containing naphthenic oil. Cure time was marginally lower in the case of coconut oil mixes probably due to the presence of free fatty acids. Tensile strength tear strength resilience and abrasion resistance were better than the naphthenic oil-based compounds. Compression set and hardness were marginally inferior. The coconut oil mixes had a crosslink density comparable to that of the reference compound. Thermal studies showed that the temperature of initiation of degradation was increased by 10C and the temperature at which the peak rate of degradation occured was increased by 7C. The peak rate of degradation was comparable to the control compound.
