Neoprene Explained
Excel 240 Cellular Neoprene (CR). Neoprene was the first synthetic elastomer introduced by Dupont. Neoprene is now a generic name but was originally Duponts trade name for Polychloroprene. It was developed as an oil resistant replacement for Natural Rubber. Neoprene is a soft and flexible sponge rubber with a unique molecular structure that makes it resistant to breakdown by both water and air.
