New Route for Devulcanization of Natural Rubber and the Properties of Devulcanized Rubber

Journal of Polymers and the Environment, 2011
Devulcanization of natural rubber (NR) compound was carried out by means of benzoyl peroxide as a devulcanizing agent by two different techniques namely (a) chemical process and (b) mechano-chemical process. Furthermore, the effects of time and concentration of devulcanizing agent on the devulcanization process were investigated.

Thiosalicylic acid as a devulcanizing agent for mechano-chemical devulcanization

Korean Journal of Chemical Engineering, 2010
A mechano-chemical devulcanization process for vulcanized natural rubber (NV) was investigated. Thiosali- cylic acid was used as a test devulcanizing agent in comparison to diphenyl disulfide as the reference. The optimum condition for devulcanization of NR vulcanizates (NVs) was found to be grinding of the NV and subsequent mixing with a selected ...

Recycling of rubber wastes by devulcanization

Resources, Conservation and Recycling, 2018
Abstract Disposal of used tires and rubber wastes is one of the biggest challenges of the 21st century waste management. One of the environmentally friendly possibilities of recycling this type of material is to go through the breaking of their three-dimensional structure.

Characterization and supercritical CO2 devulcanization of cryo-ground tire rubber: Influence of devulcanization process on reclaimed material

Polymer Degradation and Stability, 2014
Abstract Ground truck-tire rubber (GTR) was characterized and subsequently devulcanized in supercritical CO 2 (scCO 2 ) in the presence of Diphenyl Disulfide (DD) as devulcanizing agent. Temperature and pressure were kept respectively at 180 °C and 15 MPa and the ratio between rubber and DD was 10 wt %.

An overview on waste rubber recycling by microwave devulcanization

Journal of Environmental Management
This review deals with waste rubber recycling by devulcanization treatment using microwave method. In fact, vulcanized rubbers have been extensively used in various fields due to their superior performances. Subsequently, the massive use of such materials, especially in the automotive industry, has generated a substantial amount of wastes which are not
