Influence of Viscosity Ratio on the Mechanical, Morphological, and Rheological Properties of Thermoplastic Dynamic Vulcanizates from Devulcanized Tire Rubber and Polypropylene

Macromolecular Materials and Engineering
In this study, we examined the effect of matrix viscosity on the properties of thermoplastic dynamic vulcanizates (TDV) produced using devulcanized ground tire rubber (dGTR) and polypropylene (PP).

Chemical Upcycling of Nitrile Butadiene Rubbers to Polyamines and Polyols by Chemoselective Catalytic Hydrogenation. [PDF]

Angew Chem Int Ed Engl
We demonstrate here the transformation of NBR (Nitrile butadiene rubber) including post‐consumer waste sourced from nitrile gloves and o‐rings into polyamines and polyols via ruthenium catalyzed hydrogenation. ABSTRACT We report here two new approaches for the chemical recycling/upcycling of nitrile butadiene rubber (NBR) to make either polyamines or ...

Regeneration and devulcanization

, 2021
Every year, approximately one billion used tires reach the end of their useful life worldwide. Many of these end-of-life tires end up in landfills. They provide an ideal breeding ground for pests and become a danger to the environment. Through advanced recycling techniques, high-quality rubber shredders and other state-of-the-art equipment, used tires ...

Upscaling of a Mechanochemical Devulcanization Process for EPDM Rubber Waste from a Batch to a Continuous System

Recycling, 2023
The present work is a comparative study of the effects of mechanical shear, temperature, and concentration of a chemical agent on the devulcanization process of post-industrial ethylene propylene diene (EPDM) rubber waste. Devulcanization was carried out

Devulcanization of ethylene‐propylene‐diene monomer rubber waste. Effect of diphenyl disulfide derivate as devulcanizing agent on vulcanization, and devulcanization process

Journal of Applied Polymer Science, 2022
AbstractA systematic study was performed to understand the effects of the devulcanizing agent dibenzamido diphenyl disulfide (DBD) on the vulcanization and devulcanization process of a sulfur‐cured ethylene‐propylene‐diene monomer (EPDM) rubber. The influence of DBD on vulcanization was investigated by mixing DBD with virgin rubber and curative system.
