Success Story

Quieting Vehicular Battery Components


Customer Problem

Car owners experienced disruptive rattling noises from the battery components of their electric vehicles. The noise worried the drivers, and gave the impression of poor construction. This tarnished the auto brand and put future sales at risk.

The source of the rattling stemmed from a failure of the battery pad to retain original thickness and securely hold internal components in place, resulting in unwanted noise. This material failure is commonly referred to as low compression-set resistance.

The ethylene propylene diene monomer (EPDM) synthetic rubber pad was not working; a proven, effective gap-filler and vibration isolator was needed to prevent the rattling and repair the brand image.

The Rogers Solution - PORON® 30, 40 & 50 Formulations

Rogers PORON® materials were selected as a replacement for the EPDM pad.

The excellent compression set-resistance of PORON® materials facilitated successful long-term gap-filling and vibration isolation within the electric vehicle’s battery compartment.

Additionally, PORON® materials maintained integrity and effectiveness throughout the lengthy temperature fluctuations vehicles are commonly exposed to in everyday use.


PORON® material effectively replaced original EPDM battery pads in the affected electric vehicles.

The PORON® battery pad provided the long-term compression set resistance needed to silence the components within the battery compartment.

Most importantly, Rogers helped restore customer trust and protect the electric vehicle’s brand in the face of stiff competition.
