EPDM Orings has excellent weather resistance. Whether it is exposed to the sun for a long time, exposed to wind and rain, or facing temperature changes and humidity differences in different seasons, it can maintain stable performance. In the fields of outdoor equipment, building sealing, such as door and window seals, EPDM Orings can effectively prevent the penetration of rain and air, and will not age or crack due to long-term outdoor environment, thereby ensuring the durability of the sealing effect.

Chemical resistance

It has good tolerance to many chemicals. It can resist some common chemical reagents, such as weak acids and weak bases. In water treatment equipment and pipeline sealing in some mild chemical environments, EPDM Orings can work normally and will not react with the chemicals it contacts, ensuring the sealing and safety of the equipment.

Temperature adaptability

EPDM Orings can maintain good elasticity and sealing performance in a wide temperature range. It can work normally in the temperature range of -40℃ to 150℃. In the cold winter, it will not become brittle and lose elasticity due to low temperature; in high temperature environment, such as some areas with slightly higher temperature in the engine compartment of the car (not extreme high temperature area), it can also be reliably sealed.

2. Sealing performance

Due to its good elasticity and material flexibility, EPDM Orings can provide reliable sealing. When installed in the sealing groove and subjected to pressure, it will elastically deform according to the shape of the sealing interface, fill the sealing gap, and effectively prevent the leakage of media such as gas and liquid. This sealing performance plays a vital role in air conditioning and refrigeration systems, water supply and drainage pipe connections, and some equipment that needs to be waterproof and airtight.

3. Application fields

EPDM Orings are widely used in many fields such as construction, automobiles, HVAC, water supply and drainage. In the construction industry, it is used for sealing doors, windows, and curtain walls; in automobiles, it is used for sealing air conditioning systems and some cooling water pipelines; in HVAC equipment, it is a key component to ensure the normal operation of the system and prevent the leakage of refrigerants or hot and cold air; in the connection of water supply and drainage pipes, it ensures that water will not leak.
