Precision Rubber for EV & Energy Storage Applications
EV and energy storage applications demand sealing chemistry that holds for years — across thermal cycling, fluid exposure, vibration, and outdoor weathering. We bring 30 years of Japanese automotive-grade compound development into the next generation of mobility and grid infrastructure.
Four EV & Energy Sub-Sectors We Serve
Charging Infrastructure
- ▸ Charging gun and connector seals
- ▸ Charging cable junction gaskets
- ▸ Charging pile cabinet seals (IP67)
- ▸ Outdoor enclosure gaskets
Recommended compounds: EPDM (weather + flame-retardant grades), FKM, Silicone
Battery Energy Storage Systems (BESS)
- ▸ BESS cabinet sealing (IP67 / IP68)
- ▸ Cable gland and bushing seals
- ▸ Vibration isolation mounts
- ▸ Door and access panel gaskets
Recommended compounds: EPDM, HNBR, NBR
EV Peripheral & Manufacturing Equipment
- ▸ EV battery test rig seals
- ▸ Thermal cycling chamber gaskets
- ▸ Production-line sealing for EV component OEMs
- ▸ Drive-unit dynamometer seals
Recommended compounds: FKM, HNBR, FFKM (for plasma cleaning equipment)
EV Vehicle Tier 2 Components
- ▸ Thermal management hoses and O-rings
- ▸ Low/medium-voltage connector seals
- ▸ Vibration isolators (motor mounts, battery pack mounts)
- ▸ Sensor seals (Tier 2 supplied to Tier 1 modules)
Recommended compounds: HNBR, FKM, EPDM, ACM, AEM
Why Compound Chemistry Wins in EV Applications
Unlike legacy ICE seals, EV seals operate in:
- ▸ Continuous high-temperature exposure (thermal management hoses see 130-160°C constantly, not just at peak)
- ▸ Compression set under long-duration static load (battery pack lifecycle = 8-15 years, not warranty replacement)
- ▸ Mixed-fluid environments (coolants, dielectric fluids, electrolyte vapor)
- ▸ Vibration combined with thermal cycling
Our advantage: every compound is developed with these specific service conditions in mind — not pulled off a shelf.
How We Engage
For drawings-in-hand RFQs: 12-24h quote turnaround.
For application briefs (where you have a sealing problem but no compound selected yet): we engage in a structured 5-stage co-development process with our Japanese formulation team. Full process: 12-24 weeks ground-up; 4-8 weeks if optimizing from our existing library.
