EPDM rubber seals
EPDM (ethylene propylene diene monomer) rubber seals are commonly used in a variety of sealing applications due to their excellent properties. Here's a concise overview: ### Material Composition: - **Base Polymer:** EPDM is a synthetic rubber made by copolymerizing ethylene, propylene, and a diene monomer. - The diene monomer introduces unsaturation, allowing for cross-linking during vulcanization, enhancing the rubber's properties. ### Key Properties: 1. **Weather Resistance:** - EPDM rubber seals have exceptional resistance to weathering, UV radiation, and ozone, making them suitable for outdoor applications with exposure to harsh environmental conditions. 2. **Temperature Resistance:** - EPDM maintains flexibility and elasticity over a wide temperature range, typically from -40°C to 120°C (-40°F to 248°F). This allows for effective performance in various climates. 3. **Chemical Resistance:** - EPDM rubber is resistant to various chemicals, acids, alkalis, and
