Manufacturing Production Processes: Vulcanization of Rubber
1. 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. 2.

De-vulcanization of Tire Rubber | ILLYRIA
Vulcanization is the process by which plastic rubber is converted into the elastic rubber or hard rubber state. The process, which is brought about by the linking of macromolecules at their reactive sites, is also known as crosslinking. Vulcanizing agents are substances that bring about the actual crosslinking process.

NRT: New Rubber Technologies
Vulcanization, a chemical process for converting rubber or related polymers into more durable materials via the addition of sulfur or other equivalent "curatives" or "accelerators". and some sulfur-carbon bonds while importantly leaving intact the molecular carbon-carbon backbone created by the vulcanization process.

Charles Goodyear and the Vulcanization of Rubber
Naugatuck Emerges as Industry Hub. The vulcanization process put Naugatuck, Connecticut, on the map as a leading site of rubber manufacturing during the 19th and 20th centuries. Numerous rubber companies operated in the town under the Goodyear license, including Uniroyal, which made the popular Keds sneakers. Even today, the town’s main thoroughfare is named Rubber Avenue.

What is Vulcanized Rubber? (with pictures)
Vulcanized rubber is a natural elastomer that has been made more durable by a biochemical process that cures the rubber. During vulcanization, the milky latex from a rubber tree is combined with a curing ingredient — usually sulfur — and heated under pressure.

Difference Between Vulcanized and Unvulcanized Rubber
Rubber that has undergone the process of vulcanization is called vulcanized rubber. During the process of vulcanization, chemical bonds are formed between the independent polymer chains of a particular rubber, resulting in a molecular network within the polymer matrix.

Vulcanization
Vulcanization (British: vulcanisation) 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 (synthetic) rubbers via various means.

The Manufacturing Process of Rubber | Sciencing
The natural rubber manufacturing process begins with harvesting latex from rubber trees. Harvesting latex from rubber trees starts with scoring or cutting into the bark of the tree. Latex flows into a cup attached to the bottom of the cut in the tree. The latex material from many trees is accumulated in large tanks.
