EPDM rubber is a versatile synthetic rubber widely used in various industries for seals and gaskets due to its excellent resistance to weathering, ozone, UV exposure, and aging. Here’s a rundown of its key features and applications:

1. Weather Resistance: EPDM rubber has outstanding resistance to weathering, making it ideal for outdoor applications where exposure to sunlight, rain, and temperature fluctuations is common. This makes it suitable for automotive weatherstripping, window seals, and outdoor electrical enclosures.
2. Chemical Resistance: EPDM exhibits good resistance to many chemicals, acids, and alkaline substances, which makes it useful in applications where exposure to such substances is expected, such as in the chemical industry or in automotive systems where it may come into contact with fluids.
3. Temperature Resistance: EPDM can withstand a wide range of temperatures, from -50°C to +150°C (-58°F to +302°F), without losing its properties significantly. This makes it suitable for both hot and cold applications, such as in HVAC systems, automotive cooling systems, and steam systems.
4. Water and Steam Resistance: EPDM rubber has excellent resistance to water absorption and steam, making it suitable for use in sealing applications where exposure to moisture or steam is expected, such as in plumbing seals, steam hoses, and gaskets for food and beverage processing equipment.
5. Electrical Insulation: EPDM rubber has good electrical insulating properties, making it suitable for use in electrical enclosures, cable insulation, and gaskets for electrical equipment.
6. Durability and Longevity: EPDM gaskets is known for its durability and longevity, even in harsh environmental conditions. It resists cracking, tearing, and deformation over time, leading to longer service life compared to other rubber materials.
7. Compression Set Resistance: EPDM exhibits good compression set resistance, meaning it can maintain its shape and sealing properties even after being compressed repeatedly, making it suitable for sealing applications where frequent compression and relaxation occur.

EPDM rubber seals and gaskets find applications in various industries, including automotive, construction, HVAC, plumbing, electrical, and manufacturing. They are used in a wide range of products such as door seals, window seals, gaskets for pipes and fittings, O-rings, expansion joints, roofing membranes, and many more.
