ROGERS PORON 4790-92-12039-04P is a high-performance microcellular polyurethane foam tape engineered for precision electronic cushioning and sealing. Featuring extra-soft flexibility and excellent slow-rebound characteristics, it delivers superior shock absorption and reliable gap filling. Widely used for dustproof sealing and cushioning in smartphones, displays, and other sensitive electronics, this durable material supports custom precision die-cutting and adhesive backing to meet exact industrial requirements.

• Extra-Soft & Low Closure Force: Compresses easily under minimal pressure, making it ideal for thin, fragile electronic components without causing housing deformation or display stress.
• Excellent Compression Set Resistance: Outstanding slow-rebound and high-resiliency properties maintain thickness and sealing performance even after long-term compression.
• Microcellular Structure: The uniform, high-density microcellular open-cell structure provides exceptional dustproof sealing, preventing fine particles and moisture from penetrating.
• Superb Die-Cutting & Adhesive Compatibility: Offers clean edges during precision die-cutting without fraying, and bonds perfectly with various industrial double-sided tapes.

• Smartphones & Wearable Devices: Dustproof sealing between OLED/LCD screens and frames, plus shock absorption for camera modules, speakers, and microphones.
• Laptops, Tablets & Handhelds: Battery cushioning to absorb expansion, keyboard and trackpad gap filling, and sealing of enclosure joints.
• Automotive Electronics & Displays: Vibration damping, noise reduction (NVH), and rattle prevention in center consoles, digital dashboards, and HUDs.
• Precision Instruments & Medical Devices: Reliable, long-lasting environmental sealing gaskets for medical displays, outdoor ruggedized tablets, and industrial monitors.
