A Comprehensive Guide to EPDM Rubber in China
EPDM rubber, or ethylene propylene diene monomer, is a versatile synthetic rubber widely used in various applications due to its exceptional properties. China is a significant player in the global EPDM rubber market, boasting numerous manufacturers offering a wide range of products. This guide delves into the world of Chinese EPDM rubber, exploring its technical features, different types, and key manufacturers.
Understanding EPDM Rubber’s Technical Features
EPDM rubber stands out due to its excellent resistance to weathering, ozone, and UV degradation. This makes it ideal for outdoor applications, a key factor highlighted by manufacturers like those listed on hongjusilicone.com. Its flexibility and durability are also noteworthy, as seen in the diverse product range offered by www.shidarubber.com. The chemical resistance of EPDM varies depending on the specific formulation, but generally, it performs well against many acids, alkalis, and polar solvents. However, it’s less resistant to non-polar solvents like oils and hydrocarbons. This is a crucial consideration when selecting EPDM for specific applications. The choice between EPDM and other rubbers, like neoprene or silicone, often depends on the required balance of these properties.
| Feature | EPDM | Neoprene | Silicone | Nitrile |
|---|---|---|---|---|
| Weather Resistance | Excellent | Good | Excellent | Fair |
| Ozone Resistance | Excellent | Good | Excellent | Poor |
| UV Resistance | Excellent | Good | Good | Poor |
| Heat Resistance | Good (up to 150°C) | Good (up to 100°C) | Good (up to 200°C) | Moderate (up to 100°C) |
| Oil Resistance | Poor | Good | Excellent | Excellent |
| Chemical Resistance | Good (polar solvents) | Good (many chemicals) | Excellent (many chemicals) | Good (oils, fuels) |
| Flexibility | Excellent | Good | Excellent | Good |
| Tensile Strength | Moderate | Moderate | Moderate | Moderate |
This table shows a comparison of properties between EPDM and other types of rubber, helping to illustrate where EPDM excels and where other materials might be a better choice. Several manufacturers in China, including those on www.seals-china.net, offer a variety of these rubber types.
