EPDM rubber seals
EPDM (Ethylene Propylene Diene Monomer) rubber seals are widely used for their versatile sealing properties in various industries. Here's a comprehensive overview: 1. **Material Composition:** - EPDM is a synthetic rubber composed of ethylene, propylene, and a diene monomer, which provides the polymer with cross-linking sites during vulcanization. 2. **Key Properties:** - **Weather Resistance:** EPDM rubber seals are highly resistant to weathering, UV radiation, and ozone exposure, making them suitable for outdoor applications. - **Temperature Range:** EPDM remains flexible and elastic across a wide temperature range, typically from -40°C to 120°C (-40°F to 248°F). - **Chemical Resistance:** EPDM exhibits good resistance to various chemicals, acids, and alkalis, enhancing its suitability for different environments. - **Water Resistance:** EPDM rubber has low water absorption, making it effective for applications requiring resistance to moisture. - **Flexibility
