High Density Polyethylene/Ground Tire Rubber Composites Compatibilized by Dicumyl Peroxide

Journal of Applied Polymer Science, Volume 143, Issue 25, July 5, 2026.
ABSTRACT In this study, the thermal behavior of dicumyl peroxide (DCP) was first evaluated by differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA), which confirmed a peak decomposition temperature around 172°C, highlighting its incompatibility with standard melt‐mixing techniques for most polyolefins. To overcome this limitation,

EPDM rubber reclaim from devulcanized EPDM [PDF]

Journal of Applied Polymer Science, 2006
AbstractTwo types of ethylene–propylene–diene monomer (EPDM) rubbers, namely an efficient vulcanized (EV) and a semiefficient vulcanized (SEV), have been used to produce devulcanizates in a continuous setup. The devulcanizates are re‐cured using the same recipes as for the virgin rubber.

Deformation and Failure Mechanisms of Natural/Waste Rubber Blends Under Mechanical and Thermal Cycles: A Synchrotron In Situ Study

Macromolecular Rapid Communications, Volume 46, Issue 21, November 6, 2025.
This study explores how ground tire rubber (GTR) enhances strain‐induced crystallization (SIC) in natural rubber (NR) under mechanical and thermal cycles. Using in situ WAXD, it reveals improved reinforcement, delayed failure, and increased thermal resistance while increasing GTR content.

Synergistic Effects of Devulcanization and Liquid Polymer Activation on EPDM Rubber Waste Recycling

Journal of Applied Polymer Science, Volume 142, Issue 40, October 20, 2025.
The recycling of EPDM rubber waste by mechanochemical devulcanization and activation with liquid polymer shows promising results as a substitute for virgin rubber in high‐quality industrial products such as seals. The combination of processes depends on the degree of devulcanization. Devulcanization restores the mechanical properties of the material to
