General Characteristics
Neoprene rubber is a versatile synthetic elastomer valued for its balance of strength, flexibility, and resistance properties. It performs reliably in demanding environments where exposure to oils, weathering, or moderate heat is expected, making it one of the most widely used rubber materials across industries.

Neoprene Properties & Performance Characteristics
Neoprene is a versatile polymer valued for its wide range of desirable properties. It offers excellent resilience with a low compression set, strong flame resistance, and can be easily compounded without sulfur. It is also resistant to animal and vegetable oils, as well as many fats, greases, moderate chemicals, and various oils and solvents. However, neoprene is vulnerable to attack from strong oxidizing acids, esters, ketones, chlorinated aromatics, and nitro hydrocarbons.
Benefits of Neoprene
Common Uses for Neoprene Rubber
Neoprene rubber is widely used in industrial applications that require moderate resistance to oil, aging, weather, and ozone. Common applications include gaskets, seals, hoses, vibration isolators, and weatherstripping, particularly in automotive, HVAC, and construction industries. Its mechanical strength, flexibility, and resistance to degradation make it suitable for cable jacketing, conveyor belts, and industrial sleeves. Neoprene is also used in marine environments due to its saltwater resistance and is commonly employed in protective gear when formulated into closed-cell foam, although that differs from solid rubber applications.
