Reliable Sealing for Outdoor Environments
Outdoor equipment and structural components are continuously exposed to sunlight, ozone, rain, dust and temperature changes. An unsuitable foam material may harden, crack or lose its compression recovery after prolonged exposure.
EPDM foam rubber is widely used for outdoor sealing because it provides good resistance to weathering and ozone while maintaining flexibility under repeated compression.
Recommended EPDM Foam Products
Depending on the installation structure, EPDM foam can be supplied as:
- Closed-cell foam strips
- Extruded foam profiles
- Die-cut foam gaskets
- Adhesive-backed sealing tapes
- Continuous rolls or pre-cut lengths
Closed-cell EPDM foam is commonly selected when the application requires reduced water absorption and improved resistance to air, dust and moisture.
Key Selection Factors
The correct foam specification depends on:
- Installation gap
- Compression rate
- Foam density
- Required thickness
- Outdoor exposure conditions
- Opening and closing frequency
- Adhesive requirements
The material should compress sufficiently to create continuous contact without producing excessive closing force.
