Premium Rogers PORON 4701-60-25031-04 microcellular polyurethane foam delivers exceptional energy management and tight sealing performance. Featuring a 0.031" (0.79 mm) ultra-thin profile and a very firm, high-density (25 lb/ft³) structure, it provides superior compression set resistance and mechanical damping. Meeting UL 94 HBF flame retardant standards, this industrial-grade material is ideal for die-cutting into high-performance gaskets for EV batteries, electronics, and telecom enclosures.

• Excellent Compression Set Resistance: Retains original shape and thickness under long-term pressure for reliable, long-lasting sealing.
• Very Firm & High Density (25 lb/ft³): Provides exceptional mechanical damping, high load-bearing capacity, and superior energy absorption.
• Ultra-Thin Precision (0.79 mm): Engineered for tight-tolerance designs, ideal for compact and intricate electronic devices.
• Low Outgassing & Chemical Resistance: Will not fog or contaminate sensitive components and holds up well in harsh industrial environments.
• Flame Retardant (UL 94 HBF): Meets strict industrial safety standards for low flammability and reliable fire resistance.

• EV Battery Packs: High-performance cushioning, sealing gaskets, and vibration isolators in electric vehicle battery cells and modules.
• Telecom Equipment: Ideal for outdoor communication base stations and enclosures requiring robust dustproof and waterproof sealing.
• Industrial Enclosures: Heavy-duty door gaskets and access panel seals for control cabinets requiring high latch closure force.
• Precision Die-Cutting: Easily laminated with pressure-sensitive adhesives (PSA) such as 3M tapes for custom-stamped component pads.
