This product is the original US ROGERS PORON 4701-RS30-20020-04P high-performance microcellular polyurethane foam. Featuring a thickness of 0.51mm, it delivers excellent softness and superior compression set resistance. Equipped with a PET support layer and a pulverized surface, it is ideal for precision die-cutting. It is widely used in electronics and automotive displays for dustproof sealing, cushioning, and gap filling, ensuring long-lasting and reliable protection.

• Superb Softness & Low Closure Force: Classified as "Very Soft", it compresses easily under minimal pressure, making it ideal for protecting fragile electronic components.
• Excellent Compression Set Resistance: Features industry-leading rebound resilience, maintaining its original shape and sealing integrity even under long-term compression.
• Outstanding Processing Stability: Equipped with a PET support layer and a pulverized surface, ensuring exceptional dimensional stability during precision die-cutting without shrinkage.
• Low Outgassing & Pure Composition: Meets strict low outgassing standards, free of plasticizers, preventing chemical migration or fogging on optical displays.

• Consumer Electronics Dust Sealing: Widely used around LCD/OLED screens of smartphones, tablets, and smartwatches to block dust and moisture.
• Smart Cockpit Display Protection: Applied in automotive center consoles, digital instrument clusters, and HUD systems for vibration dampening, light-blocking, and cushioning.
• Battery Pack & Component Cushioning: Filled into gaps of battery packs or sensitive microchips to absorb micro-vibrations and prevent impact damage.
• Acoustic Enclosure Sealing: Utilized as gaskets around speakers and microphones to prevent sound leakage and optimize acoustic performance.
