EPDM rubber seals
EPDM (ethylene propylene diene monomer) rubber seals are widely used for various sealing applications due to their unique properties. Here's a comprehensive overview: 1. **Material Composition:** - EPDM is a synthetic rubber made from the polymerization of ethylene, propylene, and a diene monomer. - The diene monomer introduces unsaturation sites, allowing for cross-linking during vulcanization, which enhances the material's strength and durability. 2. **Key Properties:** - **Weather Resistance:** EPDM rubber exhibits excellent resistance to weathering, UV radiation, and ozone exposure. This makes it suitable for outdoor applications where exposure to the elements is common. - **Temperature Range:** EPDM remains flexible and elastic over a wide temperature range, from very low temperatures to high temperatures. - **Chemical Resistance:** EPDM has good resistance to a variety of chemicals, acids, and alkalis. However, it may have lower resistance to oils and hyd
