Neoprene, chemically known as polychloroprene (CR), is one of the longest-established synthetic rubbers in industry, used since the 1930s. Thanks to its balanced resistance to weathering, ozone, and moderate chemicals, it is chosen across a wide range of applications.
Key Properties of Neoprene
- Good resistance to weathering, ozone, and UV exposure
- Moderate oil and chemical resistance
- Flame-retardant characteristics (self-extinguishing tendency)
- Stable performance across a wide temperature range (-40°C to +120°C)
Mechanical and Physical Durability
Neoprene offers good flexibility and abrasion resistance, and withstands repeated flexing and stretching cycles well. These characteristics make it a suitable material for applications involving dynamic movement.
Typical Applications
- Weather-resistant gaskets and sealing elements for outdoor use
- Conveyor belts and belting applications
- Cable jacketing and electrical insulation components
- Vibration damping and isolation parts
What Sets Neoprene Apart from Other Rubbers
While EPDM offers higher weathering resistance, neoprene performs better in terms of oil resistance and flame retardancy. Compared to NBR, its oil resistance is lower, but neoprene’s weathering and ozone resistance are generally superior. The right material choice should be based on the application’s priority requirement.
