Monarch 5032 For EV Battery Vibration and Noise Damping: How A Tier 1 Supplier Moved from Problem to Prototype in 5 Days
A leading automotive converter needed a reliable, cost-effective cushion between a vehicle frame and battery case to control vibration and noise without jeopardizing an aggressive launch. Partnering with Worldwide Foam and Armacell, the team selected Monarch 5032 EPDM and moved from problem to validated solution in just five working days.
Project snapshot
- Application: Cushioning between EV battery case and vehicle frame for NVH control
- Location: Grand Rapids, MI
- Customer: Teir 1 Sutomtive Supplier
- Material: Armacell Monarch 5032 closed-cell EPDM foam (ASTM D1056 2A2)
The challenge
- An unplanned foam component late in development created budget pressure.
- The customer initially sought a UL 94‑V0 material, adding sourcing complexity amid a tight launch window.
The technical insight that unlocked savings WF’s engineers confirmed the foam would be placed outside the battery enclosure, so a UL 94‑V0 rating wasn’t required. That determination opened the door to Monarch 5032—meeting performance targets without the premium of a V0-rated material.
The solution and time line
- Material: Armacell Monarch 5032 closed‑cell EPDM, meeting ASTM D1056 2A2, with excellent recovery for long‑term vibration control and easy conversion from bun stock.
- Rapid prototyping: WF shipped material from in‑stock inventory; the Tier 1 supplier produced CNC knife‑cut samples within 24 hours for customer trials.
- Validation: esting confirmed Monarch 5032 as the right fit for the vibration‑dampening application. Total cycle time from inquiry to validated solution: five working days.
Results
- Launch protected: From first inquiry to approved samples in five working days.
- Cost control: Avoided unnecessary V0 specification while meeting performance needs.
- Production-ready supply: WF’s looping, slitting, and PSA application delivered conversion-ready materials, helping bypass supply chain bottlenecks.
