Therefore, according to Brazil, tyre rubber devulcanization is not a feasible alternative for the disposal of huge volumes of tyre wastes. Although we do not find evidence showing that devulcanization or other forms of chemical or thermal transformation such as pyrolisis pose substantial health or environmental risks, most of the evidence ...

Chemical Modifications in Styrene–Butadiene Rubber after
Thus, the development of alternatives for elastomer recycling is directly related to the actions of sustainable development and economic benefits to companies that pay to discard their wastes. The aim of this work is to evaluate the chemical modifications occurring in styrene–butadiene rubber (SBR) after microwave devulcanization.

Devulcanization of styrene butadiene rubber by microwave
Indeed, more is the degree of devulcanization, lower is the Mooney viscosity [26]. Thus, curves in Figure 14 confirmed the earlier results. The specimen generated from the ground rubber previously treated by microwave in the presence of IL exhibited Mooney viscosity close to that of the virgin rubber, proving high devulcanization of this ...

Devulcanization of waste rubber for reuse in new tires
We are investigating the devulcanization of crosslinked rubber as a sustainable method for reclaiming used car tires. Tire rubbers are among the largest sources of waste polymers in the world as their crosslinked structure and the presence of stabilizers result in their resistance to decomposition.

A Study of Scrap Rubber Devulcanization and Incorporation
devulcanization mechanism for our scrap tire devulcanization process is a selective crosslink cleavage rather than a random chain scission. The obtained devulcanized rubber was then incorporated in a virgin tire rubber compound and the impact of devulcanized rubber utilization on tire compound performance was studied.

De-vulcanization of Tire Rubber | ILLYRIA
The vulcanization of rubber by sulfur in presence of organic accelerator is a complicated process. But actually devulcanization should be the reverse process of vulcanization. Recovered rubber has some properties that are better than virgin rubber with common properties. Although vulcanization is not completely reversible.
