Rogers PORON 4701-30-15188-04 is an ultra-soft microcellular polyurethane foam with a thickness of 4.78 mm (0.188"). Featuring an optimal 15 lb/ft³ low density and excellent compression set resistance, it requires ultra-low closure force for superb dust sealing, shock absorption, and long-term cushioning. It is ideal for critical gap filling in electronics, automotive, and industrial devices.

• Ultra-Low Closure Force: The 15 lb/ft³ low density allows the foam to compress easily, preventing deformation of delicate components or plastic housings.
• Excellent Compression Set Resistance: Retains its original shape and sealing performance even after prolonged, heavy compression.
• Reliable Dust & Shock Sealing: Provides high-efficiency sealing against dust and moisture while delivering superior shock absorption and vibration damping.
• Low Outgassing & Non-Fogging: Meets strict industrial standards with no fogging, no chemical migration, and no corrosion to sensitive electronics.
• Flame Retardant: Complies with UL 94HBF and FMVSS 302 flammability ratings for safe industrial and automotive use.

• Electronics & Displays: LCD/OLED screen bezel sealing, camera lens cushioning, and critical gap filling in smartphones, tablets, and rugged devices.
• Automotive Industry: Instrument cluster sealing, ADAS sensor protection, acoustic insulation, and battery pack cushioning in electric vehicles.
• Industrial Equipment: Durable gasketing for control cabinets, medical devices, and precision instruments to isolate vibration and block dust.
• Acoustic & HVAC Sealing: High-performance sound-absorbing strips and air-filtration seals in home appliances and telecommunication enclosures.
