EPDM Cord Product Overview
EPDM Rubber Cord is a solid, round extruded rubber profile designed for sealing, cushioning, gap filling, and general industrial applications. Made from high-quality EPDM rubber, it provides excellent resistance to weathering, ozone, UV exposure, moisture, and temperature changes, making it suitable for both indoor and outdoor use.
The cord is available in a wide range of diameters, hardness levels, and lengths to meet different sealing requirements. It can be supplied in continuous rolls or cut to specified lengths and may also be joined to produce custom-sized O-rings and circular seals.
EPDM Rubber Cord is commonly used in automotive systems, construction joints, windows and doors, machinery, electrical enclosures, HVAC equipment, and marine applications. Custom colors, dimensions, tolerances, and packaging options are available for wholesale, OEM, and project-based orders.
Performance Advantages
Outdoor Durability
EPDM maintains good performance under sunlight, rain, ozone, and changing weather conditions, making it more suitable for outdoor sealing than many general-purpose rubber materials.
Reliable Flexibility
The material can compress and recover during installation, allowing it to fill gaps and accommodate minor movement between connected components.
Water and Moisture Resistance
EPDM performs well in wet environments and is commonly used for sealing applications exposed to water, humidity, and steam.
Wide Temperature Performance
EPDM Rubber Cord remains flexible across a broad temperature range. The exact working temperature depends on the selected rubber compound and application conditions.
Easy Processing
The cord can be cut, bonded, coiled, or formed into custom sealing rings, making it suitable for both standard production and project-specific requirements.
EPDM Cord vs Silicone Cord vs NBR Cord
EPDM, silicone, and NBR rubber cords are all used for sealing, cushioning, and gap-filling applications, but each material performs best under different environmental conditions. The correct choice depends mainly on temperature, outdoor exposure, oil contact, and sealing requirements.
| Property | EPDM Rubber Cord | Silicone Rubber Cord | NBR Rubber Cord |
|---|---|---|---|
| Weather Resistance | Excellent | Excellent | Limited |
| UV Resistance | Excellent | Excellent | Limited |
| Ozone Resistance | Excellent | Excellent | Limited |
| Water Resistance | Excellent | Excellent | Good |
| Heat Resistance | Good | Excellent | Moderate |
| Low-Temperature Flexibility | Good | Excellent | Moderate |
| Oil Resistance | Poor | Limited | Excellent |
| Fuel Resistance | Poor | Poor | Excellent |
| Steam Resistance | Good | Good | Limited |
| Outdoor Use | Highly suitable | Highly suitable | Generally not recommended |
| Typical Cost | Moderate | Higher | Moderate |
| Common Applications | Construction, automotive, outdoor equipment and HVAC systems | High-temperature equipment, food-processing equipment and electrical applications | Machinery, hydraulic equipment, engines and oil-handling systems |
EPDM Rubber Cord is the preferred option for outdoor sealing applications exposed to sunlight, rain, ozone, moisture, and changing weather conditions. It is widely used in windows, doors, curtain walls, automotive components, HVAC systems, electrical enclosures, and construction joints.
EPDM should not be selected for applications involving prolonged contact with petroleum-based oils, gasoline, diesel, or hydrocarbon fuels.
