EPDM sealing gasket

Dow EPDM Sealing Gasket is made from ethylene propylene diene rubber, the elastomer with the best weather resistance among general-purpose rubbers. The gasket remains elastic through years of sun and rain exposure without ozone cracking, making it the standard choice for equipment enclosures and electrical cabinets installed outdoors.

Typical Applications

• Door gaskets for outdoor electrical cabinets, control panels and technical enclosures
• Sealing street light housings, LED floodlights and waterproof power supply boxes
• Gaskets for telecom cabinets, BTS stations and fiber distribution boxes
• Seals for glazing frames, aluminum doors and partitions
• Gaskets for air ducts, fans and HVAC equipment

Advantages

1. Resistant to ozone, UV and weathering, with an outdoor service life of over 10 years
2. Good elasticity over a wide temperature range, does not become hard or brittle in the cold
3. Resistant to water, steam and many water-based chemicals
4. Available in solid, sponge and custom extruded profile forms

Application Notes

EPDM is not resistant to mineral oils, gasoline or hydrocarbon solvents, so do not use it where it will be in direct contact with oil or lubricants. Design the mounting groove so the gasket is compressed 20–30% for optimal sealing. At gasket joints, miter-cut the ends and bond them with cyanoacrylate adhesive to prevent gaps.

For frequently opened cabinet doors, sponge EPDM gaskets provide a lighter closing force while remaining watertight, extending the life of hinges and locks.
