EPDM rubber seals
EPDM (ethylene propylene diene monomer) rubber seals are widely used for sealing applications due to their excellent properties. Here's a comprehensive overview: **1. Material Composition:** - EPDM is a synthetic rubber composed of ethylene, propylene, and a diene monomer. - The diene monomer allows for cross-linking during vulcanization, enhancing the material's strength and flexibility. **2. Key Properties:** - **Temperature Resistance:** EPDM rubber seals have a broad temperature resistance range, typically from -40°C to 120°C (-40°F to 248°F). - **Weather Resistance:** Known for exceptional resistance to weathering, UV radiation, and ozone, making it suitable for outdoor applications. - **Chemical Resistance:** Generally exhibits good resistance to acids, alkalis, and polar substances, though it may not be as resistant to oils and hydrocarbons. - **Water and Steam Resistance:** Highly resistant to water and steam, making it suitable for applications expo...
