EPDM Seals – Product Introduction and Technical Properties
EPDM (Ethylene Propylene Diene Monomer) seals are high-performance rubber sealing products widely used in doors, windows, automotive systems, and various industrial applications. Known for their excellent weather resistance and long-term durability, EPDM seals are ideal for environments exposed to sunlight, ozone, moisture, and extreme temperatures.
At Jinjiang Yunli Technology Co., Ltd., we manufacture EPDM seals using 100% virgin EPDM material-never recycled rubber-to ensure superior performance, long service life, and stable physical properties.
Key Features
Excellent resistance to weathering, ozone, and UV radiation
Outstanding elasticity and long-term flexibility
Good thermal stability from low to high temperatures
Excellent performance in waterproofing, sound insulation, dust resistance, and vibration damping
Non-toxic, environmentally friendly, and compliant with international quality standards
