ABSTRACT: This paper outlines a mechanical transformation process
for rubber recycling, demonstrating the development of a new material from used tires. With the crumbs obtained
using a crusher-compactor, a novel material for the manufacture of O-rings has been
developed, with properties close to those found on the market. The process includes
an experimental methodology of a sulfur vulcanization system choice and the quantification
of ingredients, as well as the experimental determination of cure parameters. Mechanical
tests on the samples completed the work by providing the mechanical characteristics
of both unaged and aged (thermo-oxidative ageing) novel material. This process has a high potential for sustainable development and industrialization,
making it a valuable contribution to the recycling of rubber in African developing
countries.
