Why choose EPDM rubber gasket?
EPDM (ethylene propylene diene monomer) is a key material in modern sealing technologies. It is known for its excellent durability, flexibility and ability to perform in extreme weather conditions.
Technical characteristics of EPDM rubber gasket
-
Weather resistance and UV resistance
EPDM has excellent resistance to ozone, UV radiation and weathering, making it ideal for outdoor use. -
Temperature range
Works reliably from −35 °C to +100 °C, and withstands short-term surges up to +120 °C. -
Benefits of chemical resistance
Resists dilute acids, bases, salts and water vapor well – but not oils or aromatic solvents. -
Flexibility and mechanical durability
EPDM rubber gasket has good tensile strength (approx. 4 MPa on the sheet), elasticity and wear resistance.
Applications for EPDM rubber seals
-
Construction industry: Used in waterproofing, roof joint sealing, window and door seals and connector solutions.
-
Auto industry: Used in door seals, hoses and exterior components where weather and chemical resistance is required.
-
HVAC technology & industry: Excellent for seals exposed to water vapor, chemical exposure or vibration – EPDM sheet is highly resistant to both shock and sound.
-
In electrical and cables: Known as a dielectric material that is resistant to moisture, UV light, and temperature fluctuations.
Advantages of EPDM rubber gasket
| Advantage | Explanation |
|---|---|
| Pitkä käyttöikä | Resistant to UV, ozone and weathering, does not become brittle easily |
| Good flexibility | Retains elasticity over wide temperature ranges |
| Cost effective | More economical than silicone rubbers, often except for temperature ratings above 250 °C |
| Monipuolisuus | Widely used in construction, industry, automotive, electrical, and indoor and outdoor applications |
| Physically durable | Provides good wear resistance, shock absorption and noise insulation |
Summary
EPDM rubber seals stand out for their versatility, durability and cost-effectiveness. They are an excellent choice for a wide range of sealing needs – from buildings to the automotive industry and HVAC systems.
