Vulcanization (British English: vulcanisation) is a range of processes for hardening rubbers. [1] The term originally referred exclusively to the treatment of natural rubber with sulfur , which remains the most common practice.
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. It was discovered in 1839 by Charles Goodyear.

a chemical process by which rubber is made stronger: The discovery of vulcanisation allowed the widespread industrial applications of rubber. The process of vulcanization makes rubber tyres more resilient and hardwearing. Fewer examples. The rubber goes through an initial phase of processing called vulcanisation.

Vulcanisation is the process that gives rubber its elastic properties. Prior to this process rubber is has more of a gum-like consistency. It's a lot more malleable and doesn't return to shape. Vulcanisation brought about a change in public opinion with regards to rubber. The capability of rubber going back to its original shape enabled this materi...
Vulcanisation is the irreversible process of curing elastomers. Originally, vulcanisation referred exclusively to the treatment of natural rubber with sulphur, but this has grown to include the treatment of synthetic rubbers with other curatives (such as peroxide and metal oxides). During vulcanisation, cross-links are formed between the polymer ch...
There are many acceptable ways to cure rubber compounds. Vulcanisation is achieved by heating the compound at a fixed temperature for a fixed length of time under a fixed pressure to produce covalently bonded cross-links. The three vital variables are time, temperature, and pressure. Changing any one of these variables will affect how long it will ...
An open vulcanisation method. Hot air ovens can be used to vulcanise thin products. They can also be used in the post vulcanisation stage after a product has been precured in a mould. The various methods of rubber moulding create the perfect environments for the rubber to be vulcanised. The second use for hot air ovens is to remove peroxide decompo...
Autoclaves is an open vulcanisation method that is used for industrial purposes. They're cylinder-shaped pressure vessels that seal and process rubber parts. Once inside, the rubber is subjected to heat and pressure that enables crosslinks to form on the rubber. These crosslinks are what give the rubber its elasticity. The autoclave's vulcanisation...
An open vulcanisation method. Water cures can be used for products not affected by immersion. This method is useful for large items like rubber lined containers and is especially useful for hard rubber compositions. Due to the product having direct contact with the water, better heat transfer than the hot air or autoclave methods can be achieved. C...
The continuous vulcanisation in liquid baths is called the liquid curing method. In this process, the extrudate is run through a suitably hot bath immediately after leaving the extruder. The bath temperature typically ranges between 200°C-300°C consisting of salt mixtures, potassium nitrate mixtures, polyglycols, silicone oil and metal alloys. Salt...
A continuous vulcanisation method. Flat rubber goods such as conveyor belts and floor coverings are vulcanized continuously by the Rotocure method. This process involves the use of a wide steel band that presses the product against large, slowly rotating heated drums. Slow rotation of the drum allows vulcanization to occur after approximately 10 mi...
A continuous vulcanisation method. Infrared tunnels are very similar to hot air tunnels, except that the heat is supplied by infrared bulbs.
A continuous vulcanisation method. Fluidized beds are efficient vulcanization systems. They consist of small particles suspended in a stream of heated air. They are normally used for continuous vulcanization of extrusions. Heat transfer is approximately 50 times greater than with hot air alone.
The meaning of VULCANIZATION is the process of chemically treating a natural or synthetic polymer and especially rubber to give it useful properties (such as elasticity, strength, and stability). How to use vulcanization in a sentence.
Jul 24, 2021 · Vulcanization or vulcanisation (British) is a process of hardening rubber using chemicals and (usually) heat. Originally, vulcanization described the treatment of natural latex rubber with heat and sulfur. While this remains the most common type of vulcanization, the process also applies to synthetic rubber and may involve other chemicals. History
Vulcanization is a chemical process that involves the cross-linking of polymer chains in rubber using sulfur or sulfur-containing compounds, which improves the material's elasticity, strength, and durability.
