Product Introduction
1. Why EPDM for Grommets
EPDM's fully saturated backbone makes it largely immune to the degradation mechanisms that attack other rubbers outdoors - ozone cracking, UV embrittlement, oxidation, and moisture uptake. It stays flexible for decades in sun, rain, and snow. Our EPDM Rubber Grommet Customization leverages this stability for exterior cable and pipe penetrations, with optional food-grade and steam-resistant formulations for specialized industries.
2. Performance Highlights
- Survives years of direct sunlight without hardening or cracking
- Broad thermal window: stays pliable below freezing and holds shape at +150°C
- Resists hot water, steam, and dilute acids/alkalis
- Strong dielectric properties for electrical enclosure sealing
- Minimal compression set means the seal does not relax over time
- Food-safe grade available for drinking-water and food-processing lines
3. Where It Goes
- Photovoltaic combiner boxes, inverter cabinets and rooftop array wiring
- Outdoor AC condensers, heat pumps and ventilation duct penetrations
- Building facade cable entries and roof-junction sealing
- Boat deck fittings and coastal equipment exposed to salt-laden air
- Electric water heaters, washing machines and plumbing bulkheads
- Traffic signal cabinets and roadside electrical housings
- Brewery, dairy and bottling equipment (food-grade formulation)
4. What We Can Customize
- Any bore, flange diameter, groove width, or wall section from your CAD file
- Ultra-soft 30A for delicate cables up to 80A for rigid exterior panels
- Food-contact compound meeting FDA requirements
- High-heat grade for continuous +150°C duty near heat sources
- Color options: black, white, light grey, or matched to equipment finish
- Profile variants: closed-end, split, multi-bore, domed, thin-flange
- Finishing: slit for retrofit, punch-out centers, notches, kitting
5. Manufacturing & Assurance
- Compression and injection tooling to suit annual volume
- In-house mold design, CNC cutting and first-article validation
- Full inspection of critical dimensions, durometer, and surface finish
- Lot-level traceability with material certification on request
