A Comprehensive Guide to Black EPDM Rubber in China
Black EPDM rubber is a versatile material widely used in various industries across China. Its popularity stems from its excellent properties and adaptability to diverse applications. This guide delves into the technical features, different types, and manufacturing capabilities of black EPDM rubber in the Chinese market. Companies like Hebei Shida Seal Group (www.shidarubber.com) are major players in this sector.
Understanding EPDM Rubber’s Properties
EPDM, or ethylene propylene diene monomer, rubber is a synthetic elastomer known for its exceptional resistance to weathering, ozone, and UV radiation. This makes it ideal for outdoor and long-term applications. Its resilience to extreme temperatures, ranging from -40°C to +120°C, further enhances its practicality. Companies such as FAPRE INDUSTRIAL CO., LTD (www.faprerubber.com) utilize EPDM in their rubber sheet products. The material also exhibits good chemical resistance, though it is not oil-resistant. This makes it suitable for a wide array of applications.
Technical Features of Black EPDM Rubber
The specific properties of black EPDM rubber can vary based on the manufacturing process and additives used. However, some common technical features are consistently observed. These characteristics are crucial for selecting the appropriate type of EPDM for specific applications. Many Chinese manufacturers, including those found at www.zhonggaoseals.com, offer detailed specifications.
| Feature | Description |
|---|---|
| Tensile Strength | Measures the rubber’s resistance to stretching before breaking. |
| Elongation | Indicates the maximum percentage a sample can stretch before breaking. |
| Hardness (Shore A) | Measures the rubber’s resistance to indentation. Higher values mean harder. |
| Tear Strength | Measures the rubber’s resistance to tearing. |
| Compression Set | Measures the rubber’s ability to retain its original shape after compression. |
| Specific Gravity | Measures the density of the rubber. |
Different Types of Black EPDM Rubber
Black EPDM rubber comes in various forms, each tailored for specific applications. The choice depends on factors like the required hardness, flexibility, and additional properties. Hebei Shida Seal Group (www.shidarubber.com) offers a wide range of these types.
| Type | Description | Applications |
|---|---|---|
| Solid EPDM Rubber Strip | A dense, non-porous form, offering excellent durability and sealing properties. | Gaskets, seals, weather stripping, edge protection |
| EPDM Sponge Rubber Strip | A porous form, providing good cushioning, insulation, and sealing capabilities. | Automotive weather stripping, door and window seals, vibration dampening |
| EPDM Rubber Sheet | Available in various thicknesses and sizes, suitable for larger sealing projects. | Linings, gaskets, protective layers |
| Co-extruded EPDM | Combining different EPDM types (e.g., solid and sponge) for enhanced performance. | Seals requiring both sealing and cushioning properties, automotive parts |
