Effect of Castor Oil Based Multi-Functional Additive on the Properties of Natural Rubber VulcanizateBy Johnson Oboh, Peter Okolo, Kabiru Abdulwahab, Ibrahim Balarabe Mohammed, Kingsley Keme Ajekwene
Abstract: The effect of castor oil based multifunctional additives on the properties of natural rubber vulcanizate was studied. The castor oil was extracted from castor seed via mechanical expression and characterized. The castor oil based Multifunctional Additive (MFA) was synthesized by reacting castor oil with Diethylamine at temperature of 80oC under constant stirring for one hour and further cooled in a water bath to terminate the reaction. The formulation of the …

Chemical Resistance of Coconut Shell-Filled Rubber VulcanizatesBy Johnson Oboh, Peter, C. Okolo, Kingsley Kema Ajekwenene, Salako Oluwafemi
Abstract: In this contribution, the uptake of water, methanol, acetone and toluene at ambient temperature by Coconut Shell-Filled Rubber Vulcanizates as a function of time were studied. The rubber vulcanizate with varying Coconut Shell filler (CSF) concentration of 10 to 50 pphr at 10 pphr interval was prepared using two roll mixing mill and compression moulding process. The effect of filler loading on the percentage uptake of different chemicals (water, methane, …
