    This chapter reviews an efficient recycling process using supercritical carbon dioxide (scCO 2) for sulfur cross-linked natural rubber (NR).The role of scCO 2 in the devulcanization process is also described; scCO 2 works very well in facilitating the penetration of the most effective devulcanizing reagent, diphenyl disulfide, into NR vulcanizate.

    A review on devulcanization of waste tire rubber | Akca

    Rubber Industry worldwide is using on an average 50% of raw materials. These materials were mostly petroleum-based, except natural rubber (NR), steel cord and bead wire. Using of these petroleum-based raw materials not only depletes natural resources, but also produces more extreme environmental hazards.

    Tire-Derived Rubber: A Review - MDPI

    True feedstock recycling is not feasible for complex mixtures such as tires, but devulcanization can be done to reactivate the cross-linked polymer for material recycling in novel rubber products. Devulcanization, i.e., the breaking up of sulfur bonds by chemical, thermophysical, or biological means, is a promising route that has been

    Ground natural rubber (GNR) was produced from sulfur-cross-linked natural rubber obtained by mixing of natural rubber (100 phr) with ZnO (5 phr), stearic acid (2 phr), CBS (1.2) phr, and sulfur (1.8) phr using a laboratory size two-roll mixing mill at a friction ratio of 1:1.25.
