Hardening rubbers
- Vulcanization (British English: 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.

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
Oct 25, 2024 · The theory of common ancestry. The theory of common ancestry posits that all life on Earth descends from a singular “universal common ancestor.”. This foundational concept in evolutionary biology provides insight into the interconnectedness of all living organisms and how they have evolved over time through adaptation to their environments.
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.

Vulcanisation is a thermochemical process that includes a series of complicated chemical reactions involving rubber polymers, sulphur and auxiliary (supplementary) chemicals, which was pioneered by Charles Goodyear in 1839 ( Stevenson et al., 2008 ). Rubber that has been vulcanised is less flexible than rubber that has not been vulcanised.
Vulcanization is a chemical process that involves the crosslinking of polymer chains, typically through the addition of sulfur or other curing agents, to enhance the mechanical properties and thermal stability of rubber.

Jan 1, 2015 · Definition. In order to establish elastic “form-stability,” commonly designated as “Set” for a rubber compound, the separate elastomeric polymers need to be cross-linked into an overall network. As this cross-linking most often is done at elevated temperatures, it is commonly designated by the term “vulcanization.”.
