Choosing the right sealing tape depends on the application, environmental exposure, and the media the material comes into contact with. Below is a clear comparison of EPDM, NBR, and Neoprene (CR).
EPDM Sealing Tape
Properties
-
Excellent resistance to weathering, UV radiation, and ozone
-
Highly resistant to water, hot water, and steam
-
Very good elasticity over a wide temperature range
-
Not resistant to oils and fuels
Typical Applications
-
Window and door seals
-
Facade and roofing systems
-
Plumbing and heating installations
-
Outdoor applications
How to identify
-
Typically deep black, matte surface
-
Soft, rubber-like, very elastic
-
Neutral odor
In short
The best choice for outdoor use and continuous weather exposure.
NBR Sealing Tape (Nitrile Rubber)
Properties
-
Excellent resistance to oils, fats, and fuels
-
Good mechanical strength
-
Lower resistance to weather and ozone compared to EPDM
-
Medium temperature resistance
Typical Applications
-
Machinery and plant engineering
-
Hydraulic and pneumatic systems
-
Workshops
-
Oil- and fuel-related applications
How to identify
-
Black to dark grey
-
Feels firmer than EPDM
-
Slight characteristic rubber/oil smell
In short
The right material for oil and fuel contact.
Neoprene Sealing Tape (CR)
Properties
-
Good resistance to weathering and aging
-
Moderate resistance to oils and chemicals
-
Very good mechanical strength
-
Good dimensional stability
Typical Applications
-
Construction industry
-
Electrical engineering
-
Automotive and vehicle manufacturing
-
General technical applications
How to identify
-
Black, often slightly glossy surface
-
Firm feel, less elastic than EPDM
-
Typical neoprene odor
In short
A versatile all-round material where both mechanical stability and weather resistance are required.
Overview – at a glance
| Material | Weather Resistance | Oil/Fuel Resistance | Typical Use |
|---|---|---|---|
| EPDM | Excellent | No | Outdoor, construction, plumbing |
| NBR | Limited | Excellent | Machinery, oil, fuel |
| Neoprene | Good | Moderate | Technical, construction, automotive |
Conclusion
-
EPDM: Outdoor, weather, water
-
NBR: Oil, fuel, technical applications
-
Neoprene: Universal, mechanically robust
