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.

Vulcanization | rubber manufacturing | Britannica
Vulcanization, chemical process by which the physical properties of natural or synthetic rubber are improved; finished rubber has higher tensile strength and resistance to swelling and abrasion, and is elastic over a greater range of temperatures. In its simplest form, vulcanization is brought about by heating rubber with sulfur.

Our Rubber Devulcanizing Solution
Devulcanized Rubber Production Conventional vs New Devulcanizing Systems The conventional method of delinking is done in a devulcanizer where high pressure of up to 4 MPa and temperature of up to 300°C is required, and water is used as a medium. This process has its inherent safety risk due to the high pressure employed.

RUBBER CHEMISTRY - Läroverket i Småland AB
Rubbers are used most often in the form of vulcanizates - a vulcanized rubber. They can be brought to this form by vulcanization. This process is based on creation of chemical and physical transverse bonds between rubber macromolecules resulting in a spatial vulcanizate mesh, giving unique properties to the material. Various

The Manufacturing Process of Rubber - Seacon Corporation
Synthetic rubber production begins with the refining of oil, coal or other hydrocarbons. During the refining process, naphtha is produced. The naphtha is collected and can then be combined with natural gas to produce monomers such as styrene and isoprene, which are necessary for the production of synthetic rubber.

Processing and Profiting from Rubber | HowStuffWorks
Processing natural rubber consists of the following steps: Companies begin by obtaining the latex fluid, which means tapping the sap from the rubber trees, filtering the latex and then packaging it in drums for export or processing. They make smoked sheets of latex rubber.
