Sulfur-cured unfilled natural rubber (NR) is successfully devulcanized in a continuous extrusion process under the application of high-power ultrasonic energy. The die characteristics and ultrasonic power consumption are measured. A unique correlation is found between the crosslink density and gel f

## Abstract The recycling of carbon black (CB)βfilled ethylene propylene diene monomer (EPDM) rubber was carried out by using a newly built continuous ultrasonic groovedβbarrel reactor. Using this reactor, it was possible to increase by two times the output of devulcanized rubber in comparison with
Extraction of unbound materials from carbon-black-filled natural rubber (NR) vulcanizates with different cure systems was studied using various solvents with different dielectric constants of n-hexane, toluene, THF, acetone, and acetonitrile. The extraction was performed at room temperature and 40Β°C
