any of various processes by which natural or synthetic rubber or other polymeric materials may be cured or otherwise treated (i e , exposed to chemicals, heat or pressure) to render them non-thermoplastic, and which improve their elastic and physical properties
The act or process of imparting to caoutchouc, gutta- percha, or the like, greater elasticity, durability, or hardness by heating with sulphur under pressure
a process during which a rubber compound, through a change in its chemical structure, improves or extends elastic properties over a greater range of temperature
Process of changing the chemical structure of rubber, converting it so that the elastomeric state exists over a greater range of temperature; in some cases the process is extended so that the substance become rigid
Chemical process, discovered by Charles Goodyear (1839), by which the physical properties of natural or synthetic rubber are improved. It consists principally of heating rubber with sulfur; other substances (accelerators, carbon black, antioxidants, etc.) are also added. The sulfur does not simply dissolve or disperse in the rubber, but rather combines chemically, mostly in the form of cross-links (bridges) between the long-chain molecules; however, the reactions are not fully understood. Vulcanized rubber has higher tensile strength and resistance to swelling and abrasion, and is elastic over a greater range of temperatures
a process in which sulfur is added to rubber and the mixture is heated, causing crosslinking of the polymer chains and thus adding strength to the rubber
