Rogers PORON 4701-30-25037-04P is a high-performance, very soft polyurethane foam sheet laminated with a PET carrier film. Engineered for excellent flexibility, conformability, and exceptional compression set resistance, this foam delivers superior shock absorption and reliable sealing performance. It is an ideal material for gap filling, cushioning, and vibration damping in precision electronics and industrial assemblies.

• Exceptional Softness & Conformability: The very soft texture compresses easily, perfectly sealing uneven surfaces and accommodating tight dimensional tolerances.
• Excellent Compression Set Resistance: Retains original shape and thickness after long-term compression, ensuring reliable, long-lasting sealing performance.
• Superior Shock Absorption: Delivers outstanding energy management, effectively dampening high-frequency vibrations and cushioning against drops or impacts.
• Enhanced PET Support: Laminated with a permanent PET carrier that enhances dimensional stability and tensile strength for precise, distortion-free die-cutting and clean processing.
• Low Outgassing & Clean: Free of plasticizers, minimizing chemical outgassing to prevent fogging or contamination on sensitive electronic components and optical screens.

• LCD/OLED Display Gasketing: Ideal for gap-filling, dust-proofing, and light-blocking around the edges of smartphone, laptop, and automotive screens.
• Battery Cushioning: Acts as a protective pad in electric vehicle (EV) batteries or consumer electronics to absorb expansion stress and prevent vibration wear.
• Acoustic Component Sealing: Used around speakers, microphones, and receivers to isolate sound, prevent audio leakage, and improve overall acoustic quality.
• Camera Module Protection: Shields fragile sensors, lenses, and internal precision components from mechanical shocks and drops.
