The preparation of various samples of ebonite vulcanizates and their physico-mechanical properties have been
investigated using standard methods. This work explores the production of ebonite dust, production of ebonite
vulcanizates and investigation of the characterization of the ebonite. Five different ebonite materials-labeled A, B, C, D,
and E with sulphur content in parts per hundred grams of rubber (Phr) of 32, 34, 36, 38 and 40 respectively were
produced. The physico-mechanical properties carried out were tensile strength, hardness and abrasion resistance. The
tensile strength (MPa) for sample A, B, C, D and E were 5.6, 3.5, 4.7, 1.7 and 2.0 respectively while the abrasion (%mass
loss) were 8.49, 4.24, 2.59, 1.08 and 1.05 respectively and the hardness (IRHD) being 63, 64, 65, 70 and 82.The results
show that the preparation of ebonite from natural rubber as a base polymer is feasible considering the results of
characterization obtained.
