Rogers PORON 4701-43-07118-04 P is a 3.0mm thick microcellular polyurethane foam engineered as an EV battery compression pad. It delivers excellent compression set resistance to maintain stable counter-pressure during battery cell expansion cycles. Featuring a 2 mil PET film carrier, the material prevents stretching during high-speed automated assembly, ensures precision die-cutting, and provides superior electrical insulation for maximum battery pack safety.

• Exceptional Pressure Management: Delivers a flat Compression Force Deflection (CFD) curve, maintaining a stable, predictable counter-pressure during battery cell expansion to prolong cell life.
• Low Compression Set: Retains its original thickness and mechanical properties under continuous stress and elevated temperatures without collapsing or aging.
• Dimensionally Stable PET Carrier: The integrated 2 mil PET film prevents the soft foam from stretching or distorting, ensuring high precision during automated web processing and die-cutting.
• Superior Electrical Insulation: The PET liner provides excellent dielectric strength, mitigating the risk of high-voltage arcing or short circuits within the pack.

• EV Battery Cell Cushioning: Placed between lithium-ion cells (Cell-to-Cell) to absorb expansion and contraction forces during charge and discharge cycles.
• Module Isolation Pads: Used as module-to-module compression pads in EV/HEV battery packs to isolate vibration and fill structural gaps.
• Automotive Electronics Sealing: Provides reliable dust sealing, gap filling, and shock absorption for rugged electronic control units (ECUs) and sensors.
