EPDM rubber seals and gaskets are widely used in various industries for their excellent properties. Here’s a breakdown of their characteristics and applications:
- Chemical Resistance: EPDM rubber has good resistance to many chemicals, acids, and alkalis, making it suitable for applications where exposure to such substances is common. This resistance helps prevent degradation and ensures the longevity of seals and EPDM gaskets.
- Weather Resistance: EPDM exhibits exceptional resistance to weathering, ozone, and UV radiation. This property makes it ideal for outdoor applications where exposure to sunlight and harsh weather conditions is unavoidable, such as automotive weatherstripping and roofing seals.
- Temperature Resistance: EPDM rubber can withstand a wide range of temperatures, from -50°C to +150°C (-58°F to +302°F) approximately, without significant loss of properties. This makes it suitable for both hot and cold environments, such as HVAC systems and automotive engine compartments.
- Water and Steam Resistance: EPDM rubber maintains its integrity even when in contact with water and steam, making it suitable for use in plumbing systems, steam gaskets, and sealing applications where exposure to moisture is common.
- Electrical Insulation: EPDM rubber has good electrical insulation properties, making it useful in electrical enclosures, cable seals, and other applications where electrical conductivity needs to be prevented.
- Flexibility and Elasticity: EPDM rubber is highly flexible and elastic, allowing it to conform to irregular surfaces and maintain a tight seal even under dynamic conditions. This flexibility reduces the risk of leakage in sealing applications.
- Low-Temperature Flexibility: EPDM rubber remains flexible at low temperatures, which is essential for applications in cold climates or where exposure to freezing temperatures is expected.
- Compression Set Resistance: EPDM rubber has excellent compression set resistance, meaning it can maintain its shape and sealing effectiveness even after prolonged compression. This property ensures long-term reliability in sealing applications.
- Tear and Abrasion Resistance: EPDM rubber offers good tear and abrasion resistance, enhancing its durability and reliability in demanding applications where mechanical wear is a concern.
EPDM rubber seals and gaskets find extensive use in industries such as automotive, construction, aerospace, HVAC, plumbing, and electrical, among others. They are available in various shapes, sizes, and configurations to meet the specific requirements of different applications.
