Professional-grade 3M Urethane Foam Tape 4318 with charcoal gray open-cell design for superior sound dampening, vibration absorption, and sealing. Features acrylic adhesive, 125 mil thickness, and reliable performance up to 180°F.
3M™ Urethane Foam Tape 4318 is a premium conformable, low-density, open-cell foam tape engineered with a pressure-sensitive acrylic adhesive on one side. This professional-grade tape is specifically designed for industrial and occupational applications requiring superior sound dampening, vibration absorption, and sealing capabilities. The charcoal gray foam construction measures 2 inches wide by 36 yards long with a 125 mil thickness, providing exceptional cushioning and absorbency for mounting applications across multiple industries.
The tape features 3M™ Adhesive 430, a modified acrylic formulation that delivers high initial quick-stick to various substrates while maintaining excellent chemical resistance and shear holding strength at elevated temperatures. When compressed 50%, the open-cell construction creates an effective air barrier and cushion in electronic equipment, making it ideal for applications where moisture, dust, and draft sealing are critical. The silicone-treated paper liner protects the adhesive and ensures clean, attractive application results.
This versatile foam tape is suitable for use in electronics such as printers, keyboards, computers, aircraft lights, and automotive dashboards, as well as register covers, recessed lighting, and door/window/cabinet seals. With a shelf life of 24 months and performance capabilities up to 180°F (82°C) short-term and 150°F (70°C) long-term, this industrial-grade tape delivers reliable performance across diverse applications. Each case contains 6 rolls for convenient bulk purchasing.
