PRESENTATION OF NEW DEVULCANIZATION PROCESS

NIPPON GOMU KYOKAISHI, 1999
Continuous devulcanization by shear flow stage reaction control technology for vulcanized rubber has been developed. Screw geometry and alignment, screw rotation, reaction temperature, internal pressure, and addition of process oil and devulcanizing agent are the most important factors for this process.

Disulfide Exchange Reactions: The Bridge Between Processability, Performance, and High‐Throughput Recyclability in Crosslinked Elastomers

Advanced Sustainable Systems, Volume 9, Issue 2, February 2025.
A simple cross‐linking strategy is proposed using commercially available maleated polypropylene (PPgMA) and maleated ethylene propylene rubber (EPRgMA). Disulfide exchange reactions are introduced with the crosslinker, and this in combination with phase separation phenomena, enabled simple process to crosslinked elastomers with remarkable mechanical ...

Mechanical and physical properties of flexible polyurethane foam filled with waste tire material recycles

Journal of Applied Polymer Science, Volume 141, Issue 48, December 20, 2024.
Schematic procedure for fabricating polyurethane foams filled with pre‐treated ground tire rubber. Abstract In this work we use ground tire rubber (GTR) powder obtained by grinding worn tire treads as reinforcer agent in flexible polyurethane (PU). Characterization of the microstructure of the as‐received powder is achieved using a series of standard ...
