EPDM rubber seals
EPDM (Ethylene Propylene Diene Monomer) rubber seals are widely utilized for their excellent properties in various sealing applications. Here's a concise overview: 1. **Composition:** - EPDM is a synthetic rubber derived from the polymerization of ethylene, propylene, and a diene monomer. - The diene monomer introduces unsaturation sites, allowing for cross-linking during vulcanization, enhancing the material's strength and resilience. 2. **Key Properties:** - **Weather Resistance:** EPDM rubber is highly resistant to weathering, UV radiation, and ozone exposure, making it suitable for outdoor applications. - **Temperature Range:** EPDM maintains flexibility and elasticity over a broad 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, making it versatile for different environments. - **Water Resistance:** EPDM has low water absorption, contribu...
