EPDM Rubber: A Deep Dive
EPDM (ethylene propylene diene monomer) rubber is a synthetic elastomer known for its exceptional durability, flexibility, and resistance to various environmental factors. Unlike natural rubber, EPDM exhibits outstanding weather resistance, including UV radiation, ozone, and heat. This makes it ideal for outdoor applications. Its closed-cell structure provides excellent water resistance, making it suitable for sealing applications. Many companies, such as those listed on www.listcompany.org, specialize in EPDM products.
Technical Features of EPDM Rubber
Several key technical properties differentiate EPDM rubber from other elastomers. These characteristics determine its suitability for diverse applications. Consider the following comparison:
| Property | EPDM | Nitrile Rubber (NBR) | Silicone Rubber | Neoprene (CR) |
|---|---|---|---|---|
| Tensile Strength | Moderate | High | Moderate | Moderate |
| Elongation | High | Moderate | High | Moderate |
| Hardness | Variable (10-90 Shore A) | Variable (30-90 Shore A) | Variable (10-80 Shore A) | Variable (40-90 Shore A) |
| Heat Resistance | Good (up to 150°C) | Good (up to 120°C) | Excellent (up to 200°C) | Good (up to 100°C) |
| Water Resistance | Excellent | Good | Good | Good |
| Ozone Resistance | Excellent | Good | Excellent | Good |
| Chemical Resistance | Good (resistant to many chemicals) | Excellent (oil, grease resistant) | Good (resistant to many chemicals) | Good (resistant to many chemicals) |
| UV Resistance | Excellent | Poor | Good | Good |
Different Types of EPDM Rubber
EPDM rubber is available in various types, each tailored to specific applications. Key distinctions lie in their cell structure, density, and additives. This table highlights some common types:
| Type | Cell Structure | Density (kg/m³) | Hardness (Shore 00) | Temperature Range (°C) | Applications |
|---|---|---|---|---|---|
| Closed-Cell EPDM | Closed | 75-175 | 10-40 | -40 to +150 | Sealing, insulation, automotive parts |
| Mixed-Cell EPDM | Mixed | 95 | – | -40 to +135 | Automotive, electronics, appliances |
| Flame-Resistant EPDM | Closed | Variable | Variable | Variable | Applications requiring fire resistance |
| High-Temperature EPDM | Closed | Variable | Variable | Variable | Applications requiring high-temperature resistance |
