Vulcanization (British: Vulcanisation) is a range of processes for hardening rubbers. The term originally referred exclusively to the treatment of natural rubber with sulfur, which remains the most common practice. It has also grown to include the hardening of other (synthetic) rubbers via various means. Examples include … See more Rubber—latex—had been known for thousands of years in Mesoamerican cultures, used to make balls, sandal soles, rubber bands, and waterproof containers. Rubber was processed for specific applications within the See more In contrast with thermoplastic processes (the melt-freeze process that characterize the behaviour of most modern polymers), vulcanization, in common with the curing of other thermosetting polymers, is generally irreversible. Five types of curing systems are in … See more The vulcanization of neoprene or polychloroprene rubber (CR rubber) is carried out using metal oxides (specifically MgO See more • ISO 2921 • Polymer stabilizers • Sulfur concrete • Vulcanized fibre See more There are many uses for vulcanized materials, some examples of which are rubber hoses, shoe soles, toys, erasers, shock absorbers, conveyor belts, vibration mounts/dampers, … See more The most common vulcanizing methods depend on sulfur. Sulfur, by itself, is a slow vulcanizing agent and does not vulcanize synthetic polyolefins. Accelerated vulcanization is carried out using various compounds that modify the kinetics of crosslinking; this … See more Room-temperature vulcanizing (RTV) silicone is constructed of reactive oil-based polymers combined with strengthening mineral fillers.
