Evaluation of aging resistance and long-term use effect of EPDM sealing ring

EPDM seals are widely used in industrial and commercial applications because of their excellent aging resistance and compatibility with a variety of chemical media. This article will delve into the aging resistance characteristics of EPDM seals and their long-term use effects to provide detailed evaluation and guidance for relevant industry professionals.

Aging resistance analysis

Ozone and weather aging resistance: EPDM seals have excellent ozone resistance and can be used for a long time under outdoor exposure conditions, and are not prone to aging and cracking. This makes it particularly useful in fields such as construction, automotive and electronic devices.

Ultraviolet resistance: EPDM sealing ring can effectively resist the erosion of ultraviolet light, not easy to lose elasticity or harden due to long-term sunlight exposure, suitable for outdoor equipment and solar equipment and other high exposure environment.

Heat and cold resistance: EPDM seals are able to maintain excellent elasticity and sealing properties over a wide temperature range, usually withstanding operating temperatures from -50 degrees Celsius to 150 degrees Celsius, suitable for applications in a variety of climatic conditions.

Long-term use effect evaluation

Mechanical stability: EPDM sealing ring has good resistance to compression permanent deformation, long-term use can still maintain a stable sealing effect, not easy to fail due to mechanical extrusion or stretching.

Chemical stability: EPDM seals have good tolerance to chemicals such as water, acid, alkali and oxidizer, and can operate safely and stably in chemical equipment, water treatment equipment and food processing equipment.

Economy and sustainability: EPDM seals have relatively low manufacturing costs, and have a long service life, which can reduce maintenance and replacement costs, and have economic and sustainability advantages for enterprises.

Application field

Construction and engineering: Used for sealing doors and Windows, waterproof roofs, pipe connections, etc., to ensure the sealing and insulation effect of building structures in various weather conditions.

Automotive manufacturing: Seals for automotive door and window seals, engines and transmission systems to ensure the tightness and quietness of the interior of the vehicle.

Electronic appliances: Waterproof seals for electrical equipment, fixed seals for cable joints and solar panels to protect equipment from the external environment.

Sum up

EPDM seals play an important role in many industrial fields due to their excellent aging resistance, extensive chemical compatibility and stable mechanical properties. The correct selection and use of EPDM seals can significantly improve the reliability and durability of equipment and systems.
