3M™ 4718 is a medium-density, closed-cell vinyl foam tape designed for sealing, gasketing, and vibration dampening in medium thickness applications. It uses 3M™ Adhesive 430 to provide strong adhesion, good quick stick, and long-term durability.
Its closed-cell structure helps prevent moisture absorption while allowing the foam to compress and conform to irregular surfaces, making it ideal for industrial sealing applications.
