Neoprene, also known as polychloroprene, is a synthetic rubber that was first developed by DuPont chemist, Wallace Carothers in 1930. The name "neoprene" was trademarked by DuPont in 1931 and the material quickly became popular for its unique combination of properties such as good resistance to oil, chemicals, and weathering.
Neoprene was initially used as a substitute for natural rubber, which was in short supply during World War II. It was used in various applications such as fuel hoses, gaskets, and electrical insulation. The material's resistance to oil and chemicals made it a popular choice for use in industrial settings.
In the 1950s, neoprene began to be used in the production of wetsuits. The material's ability to insulate and its resistance to water made it an ideal choice for use in wetsuits. The first neoprene wetsuits were thick and stiff, but as technology improved, the material became thinner and more flexible, making it more comfortable for the wearer.
In the 1960s, neoprene was also used in the production of orthopedic braces and supports. The material's ability to provide support and compression made it an ideal choice for use in orthopedic products.
