More or less universally, bis(3‐triethoxysilyl propyl) tetrasulfide (TESPT) has been used as a coupling agent during dispersion of silica filler in a virgin nonpolar rubber compound. It is for the first time that TESPT has been used as a devulcanizing agent and as‐grown devulcanized rubber facilitates the silica dispersion in nonpolar rubber compound ...

This study aimed to compare the adsorption of Pb(II) ions from an aqueous solution using non-devulcanized (NTR) and devulcanized tyre rubber (DTR) powder. Both types of rubber particles were prepared from used truck tyres, with DTR processed through mechano-chemical devulcanization.

The disposal of recycled tires is a problem that has gained considerable importance since it has involved the environmental as well as various disciplines and points of view. Currently, the burning and outdoor storage of disposed tires are forbidden practices because of their polluting effect, damage to health and the fact that they contribute to the ...

Rubber Chemistry and Technology, 1994
Abstract The literature contains the record of numerous methods which have been used to reverse the vulcanization process. Indeed, many of these methods have long been used, especially for purposes of analysis and/or studying mechanisms of vulcanization, so that they are commonplace in most large laboratories.

Devulcanization of Guayule Rubber by Ultrasound
Rubber Chemistry and Technology, 1999Abstract The present study describes the effect of ultrasonic irradiation on vulcanized guayule rubber using 1 to 3.5 parts per hundred of rubber (phr) of sulfur as the crosslink agent. The effect on crosslink density, gel fraction, torque and glass transition temperature was measured.

Current progress in waste tire rubber devulcanization
Chemosphere, 2021Vulcanized rubber, due to its superior mechanical properties, has long been used in various industries, especially automotive. The rubber industry has evolved and expanded over the years to meet the increasing global demands for tires. Today tires consist of about 19% natural rubber and 24% synthetic rubber, while plastic polymer and metal, filler and ...

Contribution to the Mechanism of Devulcanization
Rubber Chemistry and Technology, 1957Abstract (1) Three types of natural-rubber vulcanizates have been treated under specific reclaiming conditions. The resultant products have been examined particularly for the manner of sulfur combination and for chloroform extract. The normally accepted, non-reverting tetramethylthiuram disulfide type stock was found to be by far the most ...

AbstractGround tire rubber (GTR) with crosslinked structure has hardly any plasticity and processability, which makes its property very poor. Thermal‐mechanical shearing devulcanization method can effectively destroy the crosslinked structure and restore GTR a certain extent of plasticity and processability. This article investigated the characteristic

Contributions to the Mechanism of Devulcanization II
Rubber Chemistry and Technology, 1958Abstract Certain aspects of the reclamation of natural, butyl, and GR-S rubbers have been considered. While there are specific characteristic changes in all cases, e.g., zinc sulfide formation, etc., at the same time, important differences are recorded.

A Mechanistic Approach to EPDM Devulcanization
Rubber Chemistry and Technology, 2008Abstract The extensive utilization of rubber in a wide variety of products causes a problem in terms of waste. Reclaiming of end-of-life products or production scrap is a potential solution. A high quality reclaim would preferably be obtained by devulcanization, to leave the polymer chains intact. Reclaiming of natural rubber is common practice,
