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 ...
Chloroprene is a colorless volatile liquid, almost exclusively used as a monomer for the production of the polymer polychloroprene, better known as neoprene, a type of synthetic rubber. History [ edit ]
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 ...
The new material was announced at the Rubber Division of the American Chemical Society on November 2, 1931, and was named with the trademark Duprene [1] (today the generic name is neoprene). By this time the Stevenson Act had been repealed and the Great Depression had begun. Rubber prices were low and the new material cost twenty times what ...
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.
Hypalon is a chlorosulfonated polyethylene (CSPE) synthetic rubber (CSM) noted for its resistance to chemicals, temperature extremes, and ultraviolet light.It was a product of DuPont Performance Elastomers, a subsidiary of DuPont. [1]
Other materials used to alleviate this are PVC, nitrile, and neoprene. Natural rubber that has been chemically treated to reduce the amount of antibody generators , such as Vytex Natural Rubber Latex , can be used to produce a glove that retains the properties of traditional rubber while exposing the user to significantly reduced amounts of ...
Science in History is a four-volume book by scientist and historian John Desmond Bernal, published in 1954. It was the first comprehensive attempt to analyse the reciprocal relations of science and society throughout history. It was originally published in London by Watts. There were three editions up to 1969.
