SR-S-48P is a high-performance, ultra-thin microcellular polyurethane foam manufactured by INOAC. Innovatively thermocompressed with a PET support film, this material features a 0.3mm thickness and a high density of 480 kg/m³, balancing excellent flexibility with superior tensile strength. It delivers outstanding shock absorption, cushioning, and dustproof sealing capabilities. It is widely engineered for internal component protection and sealing in precision electronics, such as smartphones, laptops, and LCM displays. Custom adhesive backing and precision die-cutting services are available.

• With a mere 0.3mm thickness and a high density of 480 kg/m³, it is perfectly engineered for extremely compact internal spaces.
• The low-rebound microcellular structure efficiently absorbs impact energy, protecting fragile internal electronic components.
• Offers superb compression set resistance, ensuring long-lasting, tight seals against dust and moisture micro-penetration.
• Highly flat surface makes it ideal for precision die-cutting and laminating with various double-sided adhesive tapes.

• Used as dustproof gaskets and cushions around camera modules, speakers, microphones, and internal housing.
• Applied in screen bezel sealing, battery cushioning, under-keyboard support, and shock absorption for motherboard brackets.
• Placed between the LCM/OLED panel and the middle frame for light-blocking, dustproofing, shock absorption, and preventing display distortion (mura effect).
• Utilized in automotive dashboards and navigation screens for anti-rattling (NVH), vibration damping, and sealing.
