When to choose neoprene seals and their advantages?
Sealing gaskets play a crucial role in the performance and durability of industrial equipment. Among the many available options, neoprene (CR) gaskets stand out for their balance between chemical resistance, mechanical properties, and aging behavior.
What is neoprene?
Neoprene (CR - Chloroprene) is a synthetic elastomer derived from polychloroprene, developed by DuPont in 1931. Its chemical structure provides excellent aging resistance, good performance against moderate oils, and great thermal and mechanical stability.
Unlike other elastomers such as NBR (nitrile), neoprene does not degrade as quickly when exposed to ozone and ultraviolet light, making it an ideal choice for outdoor applications.
Neoprene properties in sealing gaskets
Neoprene gaskets offer a balance between flexibility, mechanical strength, and durability, making them suitable for various industrial applications. Their main properties include:
- Weather resistance: Unaffected by exposure to ozone, UV rays, and harsh weather conditions, making it ideal for outdoor applications.
- Good resistance to moderate oils and chemicals: Tolerates mineral oils, greases, and some mild chemicals, though it is not the best option against aromatic hydrocarbons or aggressive solvents.
- Excellent elasticity and mechanical strength: Maintains flexibility even at low temperatures, with good tensile and tear resistance.
- Thermal resistance: Can operate within a temperature range of -40°C to +100°C, depending on the specific formulation.
- Flame-retardant properties: In certain formulations, neoprene is self-extinguishing, making it suitable for applications requiring fire resistance.
When to choose neoprene gaskets?
Neoprene sealing gaskets are an excellent choice in the following cases:
- Outdoor applications: Due to its aging resistance, it is used in equipment exposed to the elements, such as machinery housings, HVAC systems, construction, and automotive industries.
- Environments with moderate oils and mild chemicals: Suitable for low-demand hydraulic systems and environments with industrial greases.
- Electrical and thermal insulation: Used in the electrical industry due to its good dielectric properties.
- Naval and railway industries: Thanks to its resistance to saltwater and flame-retardant capabilities in some formulations.
