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 ...
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 By this time the Stevenson Act had been repealed and the Great Depression had begun.

Ira Williams (1894–1977 [1]) was an American chemist at DuPont's Jackson Laboratory in New Jersey, who in the summer of 1930, [2] together with Wallace Carothers, Arnold Collins and F. B. Downing, made commercial Neoprene possible [3] by producing a soft, plastic form of chloroprene that could be processed by the rubber industry.
