Vulcanization of Rubber
Abstract. Although the improvement in the properties of natural rubber (NR) brought about by vulcanization with sulfur was discovered by Goodyear and by Hancock 130 years ago and the process has since become the basis of a world-wide commercial manufacturing industry, a scientific understanding of the changes taking place has begun to emerge only in the last 30 years.

Compounding and Vulcanization | Springer for Research
The performance properties can be controlled by properly selecting and adjusting various compounding ingredients. The stages of rubber product manufacturing are broken down into three primary classes: selection of compounding ingredients, mixing or compounding, and vulcanization techniques or final product manufacturing process.

Differential model accounting for reversion for EPDM
One of the main drawbacks of EPM/EPDM rubber vulcanization by peroxides is the lack of selectivity, which leads to a number of side reactions. The reaction mechanisms at the base of peroxides...

The 4 Most Common Rubber Manufacturing Processes - The
During the vulcanization process the rubber may swell or shrink, after vulcanization the length of the rubber extrusion may be impacted as well. Extrusion manufacturing has the advantage of being able to produce products in high volumes at a lower production cost. Some of the common rubber products produced from extrusion includes profiles ...

The Compounding and Vulcanization of Rubber
Abstract. Traditionally, the compounder has been a trained chemist or chemical engineer. This background is necessary since some of the processes involve complicated chemical reactions, of which vulcanization is the most important. In addition, chemical analysis of the raw materials and of the completed products may be required.

Vulcanization and the mechanical response of rubber
Hyperelastic models are widely used to describe the mechanical response of rubber. However, purely mechanical models cannot account for changes in the material due to chemical reactions such as those that take place during vulcanization. Here, we present a model developed within a thermodynamic framework accounting for chemical reactions.

Effects of Composition and Dynamic Vulcanization
Rheological behavior of isotactic polypropylene (PP) and nitrile rubber (NBR) blends, in the composition range of 10–30-wt % NBR content were studied, with special reference to the effect of blend ratio, dynamic vulcanization and compatibilization. All blends were prepared in a twin-screw extruder. Capillary Rheometry was employed.
