The Comprehensive Guide to EPDM O-Ring Cord in China
EPDM O-ring cord, a crucial sealing component, is widely used across various industries in China. This guide delves into its properties, types, and applications, focusing on the Chinese manufacturing landscape. Companies like Ningbo Bodi Seals Co., Ltd. (www.bodiseals.com) are prominent players in this market, supplying high-quality cords globally. Understanding the nuances of EPDM O-ring cord is essential for optimal sealing performance in diverse applications.
Understanding EPDM O-Ring Cord
EPDM, or Ethylene Propylene Diene Monomer, is a synthetic rubber known for its exceptional resistance to heat, ozone, and weathering. This makes EPDM O-ring cord an ideal choice for outdoor applications and environments with harsh conditions. Its excellent elasticity ensures a tight seal, even under pressure fluctuations. Many Chinese manufacturers, such as those listed on www.rubberplasticparts.com, specialize in customized EPDM O-ring cord solutions.
Technical Features of EPDM O-Ring Cord
The performance of EPDM O-ring cord is influenced by several key factors. These characteristics must be carefully considered when selecting a cord for a specific application. Choosing the right cord is critical for ensuring the longevity and effectiveness of the seal. Let’s examine these features in more detail:
| Feature | Description |
|---|---|
| Material | EPDM (Ethylene Propylene Diene Monomer) rubber, often with added fillers and modifiers |
| Durometer (Shore A) | Indicates hardness; typical values range from 50 to 90. Higher numbers mean harder material. |
| Tensile Strength | Measures the material’s resistance to stretching before breaking. |
| Elongation | Percentage of stretch before breaking; higher values indicate greater elasticity. |
| Temperature Range | Operating temperature limits; EPDM typically performs well in a wide range. |
| Chemical Resistance | Resistance to various chemicals and fluids; EPDM is known for its good resistance. |
| Compression Set | Measures permanent deformation after compression; lower values are preferred. |
Different Types of EPDM O-Ring Cord
O-ring cord is not limited to a single profile. Various cross-sectional shapes cater to different sealing groove designs and applications. The choice depends on the specific needs of the sealing system. Savvy Rubber (savvyrubber.com) offers a range of options.
| Type | Cross-Sectional Shape | Advantages | Disadvantages |
|---|---|---|---|
| Standard | Circular (O-shaped) | Most common, cost-effective | May not provide optimal sealing in all grooves |
| Square | Square (▢-shaped) | Better sealing than standard in some applications | Less common, potentially higher cost |
| Rectangular | Rectangular (▭-shaped) | Ideal for rectangular grooves | Least common, potentially highest cost |
| Quad Ring (X-Ring) | Quad (X-shaped) | Excellent sealing, suitable for dynamic use | Most expensive |
Applications of EPDM O-Ring Cord
EPDM O-ring cord’s versatility makes it suitable for a vast array of applications. Its resistance to various elements makes it a popular choice in numerous industries. Xiamen Seals Technology Co.,Ltd (www.sealsmanufacturer.com) highlights its diverse uses.
The automotive industry utilizes EPDM O-ring cord extensively in sealing systems for engines, transmissions, and other components. Plumbing and HVAC systems also benefit from its resistance to water and chemicals. Other applications include industrial machinery, appliances, and medical devices. The specific type and size of cord are chosen based on the application’s requirements.
Choosing the Right EPDM O-Ring Cord
Selecting the appropriate EPDM O-ring cord involves considering the application’s specific needs. Factors such as temperature extremes, exposure to chemicals, and the shape of the sealing groove all play crucial roles in this decision.

FAQs
1. What is the difference between EPDM O-ring cord and a standard EPDM O-ring?
EPDM O-ring cord is a continuous length of EPDM rubber with a circular cross-section. A standard O-ring is a pre-formed ring. The cord offers flexibility to create custom-sized O-rings.
2. How do I determine the correct size of EPDM O-ring cord for my application?
Measure the diameter of the groove where the seal will be placed. Consider the cross-sectional shape needed (circular, square, rectangular, or quad). Consult size charts provided by manufacturers for the appropriate cord size.
3. What is the typical temperature range for EPDM O-ring cord?
The temperature range varies depending on the specific EPDM formulation and additives. Generally, EPDM O-ring cord can withstand temperatures from -50°C to +150°C (-58°F to +302°F).
4. Is EPDM O-ring cord resistant to chemicals?
EPDM exhibits good resistance to many chemicals, including ozone, weathering, and certain acids. However, it is not resistant to all chemicals. Check the manufacturer’s specifications for chemical compatibility.
5. Where can I find reliable suppliers of EPDM O-ring cord in China?
Many reputable manufacturers and suppliers of EPDM O-ring cord operate in China. Online directories, industry trade shows, and direct contact with manufacturers are effective ways to identify reliable sources.
