Chloroprene, Neoprene® O-Rings & Seals
The material of Neoprene® O-rings is chemically known as polychloroprene but often referred to by the trade name Neoprene®. Chloroprene was one of the first synthetic materials developed as an oil-resistant substitute for natural rubber. Chloroprene has good resistance to oxygen, ozone, and UV light. Due to the similarity of their structures, natural rubber and chloroprene are generally comparable in their good strength, abrasion resistance, resilience, elongation, and strain crystallisation characteristics. Both also offer a similar low fatigue property, low heat buildup, low temperature flexibility, and high bond-ability. Chloroprene surpasses natural rubber in its resistance to aging, heat, oils, ozone, and solvents. Chloroprene has also gained FDA approval for use in the food and beverage industries.
