1. Water Resistance: Neoprene rubber cord is highly resistant to water, making it suitable for sealing applications where exposure to moisture is expected. It is commonly used in marine environments for sealing hatches, windows, and doors on boats and ships.

2. Weather Resistance: Neoprene rubber cord exhibits good resistance to weathering and ozone, making it suitable for outdoor applications where exposure to sunlight and environmental elements is a concern. It maintains its physical properties and sealing performance over a wide range of weather conditions.

3. Temperature Resistance: Neoprene rubber cord performs well over a moderate temperature range, typically from -40°C to 100°C (-40°F to 212°F). It remains flexible and resilient within this temperature range, making it suitable for use in both indoor and outdoor applications.

4. Oil Resistance: While not as resistant to oils and fuels as some other elastomers like NBR or FKM Viton, neoprene rubber still offers moderate resistance to these substances. It can be used in applications where incidental contact with oils or fuels may occur.

5. Sealing Performance: Neoprene rubber cord provides good sealing performance due to its flexibility, resilience, and ability to conform to irregular surfaces. It is commonly used in gaskets, O-rings, and seals for machinery, automotive, HVAC, and plumbing applications.

6. Shock Absorption: Neoprene rubber has excellent shock-absorbing properties, making it suitable for applications where vibration damping and impact resistance are important. It is used in various industrial and recreational applications such as cushioning mounts, gaskets, and bumpers.

7. Electrical Insulation: Neoprene rubber cord has good electrical insulation properties, making it suitable for use in electrical enclosures, panels, and wiring harnesses where protection against electrical conductivity is required.

Neoprene rubber cord is available in various diameters, hardness levels (durometer), and colors to suit different sealing requirements and application specifications. It can be easily cut, molded, or formed to create custom seals and gaskets for specific industrial or commercial applications.
