Manufacturing Production Processes: Vulcanization of Rubber
Pressure Vulcanization. This process is the most typical process of vulcanization and involves heating the rubber with the use of sulfur and pressure at 150 degrees C. Other chemicals and agents can be used throughout the process, such as fillers to increase strength and resistance to wear and tear, or carbon black that acts as a reinforcer.

Removal of the 2-Mercaptobenotiazole from Model Wastewater
2.1. Characterisation of Wastewater. The wastewater from rubber industry contains more than 200 mg·L −1 of 2-MBT [1, 15].Similar content of 2-MBT was measured in the wastewater produced from N-cyclohexyl-2-benzothiazol-sulfenamide [16, 17].The concentration of MBT in model wastewater varied from 661 to 1055 mg L −1 for this set of experiments.

The 4 Most Common Rubber Manufacturing Processes - The
Some of the most common rubber manufacturing processes are extrusion, latex dipping, molding, and calendering. Extrusion begins with an unvulcanized compound being fed into an extruder. Once it’s inside the extruder, it gets carried forward to a dye, which is a specialized manufacturing tool used to shape the rubber.

Vulcanization
Vulcanization is a chemical process, invented by Charles Goodyear, used to harden rubber. Vulcanization traditionally referred to the treatment of natural rubber with sulfur and this remains the most common example, however the term has also grown to include the hardening of other rubbers via various means. Examples include silicone rubber via room temperature vulcanizing and chloroprene rubber using metal oxides. Vulcanization can therefore be defined as the curing of elastomers; with the terms

The Manufacturing Process of Rubber | Sciencing
The rubber production process begins with natural or synthetic rubber. Natural rubber comes from latex. Synthetic rubber derives from molecular polymers. Whether natural or synthetic, rubber continues through four steps: compounding, mixing, molding and casting, and, finally, vulcanization.
