EPDM rubber seals
EPDM (Ethylene Propylene Diene Monomer) rubber seals are widely used for various sealing applications due to their excellent properties. Here's a detailed overview: **1. Material Composition:** - EPDM is a synthetic rubber made through the polymerization of ethylene, propylene, and a diene monomer. - The specific formulation can be adjusted to achieve different properties such as hardness, flexibility, and resistance to environmental factors. **2. Key Properties:** - **Weather Resistance:** EPDM rubber is known for its exceptional resistance to weathering, UV radiation, and ozone exposure, making it suitable for outdoor applications. - **Temperature Tolerance:** EPDM maintains flexibility across a wide temperature range, from -40°C to 120°C (-40°F to 248°F). - **Chemical Resistance:** EPDM has moderate resistance to chemicals, acids, and alkalis. However, it may not be suitable for prolonged exposure to certain oils and solvents. - **Flexibility and Elasticity:*
