UV Resistant EPDM Gasket Performance
UV Exposure Resistance
EPDM material is formulated for sealing applications exposed to sunlight and UV radiation, helping reduce surface degradation during prolonged outdoor exposure.
Weathering Resistance
The gasket is designed for outdoor environments involving sunlight, moisture, humidity, and temperature changes, supporting longer-term material performance.
Sealing Contact Retention
The EPDM gasket maintains contact between mating surfaces under the specified compression conditions, helping limit water, dust, and environmental contaminants from entering the sealed area.
Outdoor Aging Performance
Suitable EPDM formulations can reduce premature hardening, cracking, and embrittlement associated with prolonged outdoor exposure, depending on the compound and service conditions.
- Dimensional Inspection
Gasket thickness, inside diameter, outside diameter, and profile dimensions are measured against the specified tolerances to confirm fit during assembly.
- Hardness Testing
Shore A hardness is checked according to the specified material grade to maintain consistent compression behavior between production batches.
- Material Verification
EPDM compound specifications are verified against the required material formulation before production and during quality control procedures.
- Surface & Profile Inspection
Finished gaskets are inspected for cuts, molding defects, excessive flash, surface contamination, and profile irregularities that could affect installation or sealing contact.
FAQ
How should I choose the right EPDM gasket thickness?
Gasket thickness should be selected according to the available sealing gap, mating surface condition, and required compression after assembly. The original gasket specification or equipment drawing is useful for confirming the required thickness.
Can UV resistant EPDM gaskets be used with painted or coated surfaces?
They can be used where the coating is compatible with EPDM and does not contain components that may cause rubber degradation. Surface condition and coating adhesion should also be considered during assembly.
How long can an EPDM gasket remain outdoors?
Service life varies with UV intensity, temperature cycling, moisture, compression, and the specific EPDM formulation. For long-term outdoor projects, the expected exposure conditions should be provided when selecting the material.
Can these gaskets be supplied in continuous or custom profiles?
Yes. Custom profiles can be produced according to drawings or samples, including non-standard cross-sections, sealing lips, grooves, and mounting features where required.
