a study of scrap rubber devulcanization and incorporation
A Study of Scrap Rubber Devulcanization and Incorporation
devulcanization mechanism for our scrap tire devulcanization process is a selective crosslink cleavage rather than a random chain scission. The obtained devulcanized rubber was then incorporated in a virgin tire rubber compound and the impact of devulcanized rubber utilization on tire compound performance was studied.

Recycling of waste tire rubber: Microwave devulcanization
This study focused on the possibility of recycling Waste Tire Rubber (WTR) to be used as polymer modifier. Thus, WTR was grinded into powder, at ambient temperature, with a disc mill PQ500 and microwave electromagnetic energy was used to devulcanize this powder with the final aim of producing a new composite by its incorporation in a thermoset resin.

Devulcanization of Scrap Tire Rubber with Supercritical
The devulcanization reactions of ground tire rubber (GTR) and thermoplastic elastomer (TPE) mixtures performed during the melt-extrusion process through the induction of high shear stress by increases in the screw rotation speeds and reaction temperatures were investigated in this study.

Devulcanization of Scrap Tire Rubber with Supercritical CO
Experiments have been carried out on an industrial scale twin screw extruder to study the effects of processing conditions on the properties of devulcanized rubber. Using a fractional factorial design in three levels, the effects of process temperature, screw speed, and feed rate on the sol fraction, degree of devulcanization, Mooney viscosity, and tensile properties of devulcanized rubber have been investigated.

Send InquiryTyromer | Tread Lightly
Tyromer devulcanizes scrap tire rubber for reuse in new tires. Our carbon dioxide assisted extrusion technology works without devulcanization chemicals or chemical solvents to continuously convert scrap tire crumb into an elastomeric TDP, or Tire-Derived Polymer. TDP can be used at much higher percentages than other recycled rubber, and is already

Technologies & Products - Devulcanized or Micronized
Devulcanized products & technology. Rubber scraps or used rubber cannot simply be melted down and reused as many polymers can be. That is because rubber has been cross-linked; most of the time with sulfur in a process called vulcanization invented by Charles Goodyear in 1839. Vulcanization imparts needed mechanical properties...

Devulcanization of waste rubber for reuse in new tires. The objective of this research is to develop a tire reclamation strategy to convert the waste to a high value material through a chemical process that breaks the crosslinking sulfide bonds without large effects on the main chain. This process is envisioned to revert...
