The Ultimate Guide to EPDM Gasket Suppliers in China
Finding reliable EPDM gasket suppliers is crucial for various industries. China, with its extensive manufacturing capabilities, offers a wide range of suppliers catering to diverse needs. This guide will navigate you through the landscape of Chinese EPDM gasket suppliers, providing insights into their offerings and helping you make informed decisions.
Understanding EPDM Gaskets
EPDM (ethylene propylene diene monomer) rubber is a popular material for gaskets due to its excellent properties. It exhibits high resistance to ozone, UV radiation, and weathering, making it suitable for outdoor applications. Its chemical resistance is also noteworthy, withstanding many acids, alkalis, and other chemicals. However, it’s less resistant to oils and fuels compared to other materials. Companies like www.shidarubber.com specialize in EPDM rubber products, showcasing their expertise in this area.
Technical Features of EPDM Gaskets from Different Suppliers
The technical specifications of EPDM gaskets can vary depending on the manufacturer and specific application. Factors such as hardness, tensile strength, elongation, and temperature resistance are critical. Let’s compare some key features:
| Feature | Supplier A (Example) | Supplier B (Example) | Supplier C (Example) |
|---|---|---|---|
| Hardness (Shore A) | 60-70 | 50-60 | 70-80 |
| Tensile Strength (MPa) | 8-10 | 7-9 | 9-11 |
| Elongation at Break (%) | 300-400 | 250-350 | 350-450 |
| Temperature Range (°C) | -40 to +150 | -30 to +140 | -50 to +130 |
| Chemical Resistance | Good (specific details) | Good (specific details) | Good (specific details) |

Types of EPDM Gaskets and Their Differences
EPDM gaskets come in various types, each designed for specific applications and performance requirements. The choice depends on factors such as pressure, temperature, and the fluid being sealed.
| Gasket Type | Description | Advantages | Disadvantages |
|---|---|---|---|
| Flat Gaskets | Simple, cost-effective design. | Easy to install, widely available. | Limited sealing performance at high pressures. |
| Molded Gaskets | Custom shapes and sizes for specific applications. | Precise fit, superior sealing. | More expensive, longer lead times. |
| Spliced & Vulcanized | Multiple pieces joined and vulcanized for larger gaskets. | Suitable for large, complex shapes. | Requires specialized manufacturing. |
| Envelope Gaskets | PTFE wrapped around a core material. | Combines PTFE’s benefits with core material’s strength. | More complex manufacturing process. |
| Ring Joint Gaskets (RTJ) | Precision-machined metal gaskets for high-pressure applications. | Excellent sealing at high pressures. | Requires specialized flanges. |
Note: This table provides a general overview. Specific properties will depend on the manufacturer and materials used. www.china-rubber-gaskets.com provides a good overview of various rubber gasket types. www.yosonseals.com might also offer a range of EPDM gasket types, but further investigation of their website is needed.
Selecting an EPDM Gasket Supplier
Choosing the right supplier involves considering various factors. These include the supplier’s experience, certifications (ISO, IATF), manufacturing capabilities, quality control measures, and pricing. It’s also important to assess their ability to meet your specific requirements, including custom designs and order volumes. Checking reviews and testimonials can also provide valuable insights.
Conclusion
