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.

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 By this time the Stevenson Act had been repealed and the Great Depression had begun.

Drop of water on 100% polyester textile. Waterproof/breathable fabrics resist liquid water passing through, but allow water vapour to pass through. Their ability to block out rain and snow while allowing vapour from sweat to evaporate leads to their use in rainwear, waterproof outdoor sports clothing, tents, and other applications.
