Benefits of EPDM Rubber as Medical Seals
EPDM rubber is an ideal choice for medical device seals for several reasons:
- Chemical Resistance
EPDM has good chemical resistance to dilute acids, bases, and polar solvents such as ketones and alcohols. This makes it suitable for medical applications that require contact with a variety of chemicals, such as chemical processing, wastewater treatment, and the pharmaceutical industry.
- Wide Temperature Range
EPDM seals can withstand temperatures ranging from low temperatures of -67°F to high temperatures of 257°F. This temperature resilience allows them to maintain their physical properties in cold climates or high-temperature applications such as steam systems, minimizing the risk of seal failure caused by thermal fluctuations.
- Water and Steam Resistance
EPDM rubber has excellent water and steam resistance. This is very useful during the sterilization process of medical devices to ensure that the seal can withstand high-temperature steam without losing performance.
Products Application
Medical EP (ethylene propylene rubber) seals are also widely used in the medical field. EP rubber is a synthetic rubber with good wear resistance, chemical resistance, and high-temperature resistance, and is suitable for seals in medical equipment and instruments.
The following are some common applications of medical EP rubber seals：
Medical device seals; infusion set seals; medical valve seals; medical gaskets
