3M™ Vinyl Foam Tape 4508 is a black, 0.125 in (3.2 mm) thick high-density closed-cell foam tape designed for demanding gasketing, cushioning, damping, and insulating applications. Engineered with a durable acrylic adhesive on one side and a silicone-treated paper liner, it offers quick-stick adhesion to metals, glass, and plastics while minimizing stretching during installation. Its conformable structure ensures reliable sealing on curved or irregular surfaces, making it ideal for use in HVAC systems, appliance assembly, and equipment enclosures where dust, light, and moisture resistance are critical. With excellent aging characteristics and flexibility under elevated temperatures and UV exposure, 3M™ Vinyl Foam Tape 4508 delivers consistent performance in industrial environments that require long-lasting, vibration-dampening seals.
