Protecting Sensitive Electrical Equipment
Electrical enclosures require reliable sealing around doors, panels, cable access areas and equipment covers. Gaps between metal components may allow dust, air and moisture to enter the enclosure.
EPDM foam gaskets provide flexible compression and can help create consistent sealing contact between enclosure surfaces.
Suitable Product Forms
EPDM foam for electrical enclosures can be manufactured as:
- Rectangular sealing strips
- Custom die-cut gaskets
- Adhesive-backed foam tapes
- Joined frame gaskets
- Customized extruded profiles
Adhesive backing can support accurate positioning during assembly and reduce movement before the enclosure door is closed.
Closed-Cell Foam for Enclosure Sealing
Closed-cell EPDM foam is commonly recommended for enclosure applications because its cellular structure can help limit water and air penetration when properly compressed.
Final sealing performance depends on the complete assembly, including:
- Enclosure design
- Surface flatness
- Gasket thickness
- Compression level
- Corner connection
- Fastener spacing
The gasket should not be selected based only on thickness. Density and compression force must also match the enclosure structure.
Customized Manufacturing
OKIN can produce EPDM foam gaskets according to enclosure drawings, sample parts or required dimensions. Available processing options include adhesive lamination, die cutting, length cutting and custom packaging.
