Because of its tolerance of extreme conditions, neoprene is used to line landfills. Neoprene's burn point is around 260 °C (500 °F). [21] In its native state, neoprene is a very pliable rubber-like material with insulating properties similar to rubber or other solid plastics. Neoprene foam is used in many applications and is produced in ...
Vulcanization can be defined as the curing of elastomers, with the terms 'vulcanization' and 'curing' sometimes used interchangeably in this context. It works by forming cross-links between sections of the polymer chain which results in increased rigidity and durability, as well as other changes in the mechanical and electrical properties of ...
[14] [15] [16] Only one fatality as a result of chloroprene intoxication has been recorded which was a result of cleaning a container used for chloroprene. [ 16 ] The primary occupational concern for chloroprene is limited to the facilities producing chloroprene and using chloroprene to produce the synthetic rubber, polychloroprene.
Indigo dye – Indigo, a blue pigment and a dye, was used in India, which was also the earliest major centre for its production and processing. [2] The Indigofera tinctoria variety of Indigo was domesticated in India. [2] Indigo, used as a dye, made its way to the Greeks and the Romans via various trade routes, and was valued as a luxury ...
Thus, the science of accelerators and retarders was born. An accelerator speeds up the cure reaction, while a retarder delays it. A typical retarder is cyclohexylthiophthalimide. In the subsequent century chemists developed other accelerators and ultra-accelerators, which are used in the manufacture of most modern rubber goods.
In addition to being used to model physical materials, hyperelastic materials are also used as fictitious media, e.g. in the third medium contact method. Ronald Rivlin and Melvin Mooney developed the first hyperelastic models, the Neo-Hookean and Mooney–Rivlin solids. Many other hyperelastic models have since been developed.
The gradual disuse of Latin opened an uneasy transition period as more and more works were only accessible in local languages. Many national European languages held the potential to become a language of science within a specific research field: some scholars "took measures to learn Swedish so they could follow the work of [the Swedish chemist] Bergman and his compatriots."
