Industrial-grade urethane foam tape with acrylic adhesive for sound dampening, vibration absorption, and moisture sealing in electronics and automotive applications. 2 inch x 18 yard rolls, 6 per case.
3M™ Urethane Foam Tape 4314 is a premium conformable, low-density, open-cell foam tape featuring a pressure sensitive acrylic adhesive on one side. This industrial-grade tape is specifically designed for applications requiring sound dampening, vibration absorption, and effective sealing properties. The charcoal gray foam construction, measuring 0.250 inches (6.4 mm) thick, provides excellent cushioning characteristics while maintaining high absorbency to seal out moisture, dust, and drafts across a wide range of temperatures.
The tape features 3M™ Adhesive 430, a modified acrylic pressure-sensitive adhesive that delivers high initial quick-stick to multiple substrates including metal, plastic, glass, and foam surfaces. This adhesive provides excellent chemical resistance and superior shear holding strength, even at elevated temperatures up to 180°F (82°C) short-term and 150°F (70°C) long-term performance. The adhesive reaches satisfactory adhesion within 20 minutes and continues to build strength over time, ensuring reliable permanent bonding.
Each case contains 6 rolls of 2-inch wide by 18-yard long tape, making it ideal for high-volume industrial and occupational applications. The open-cell foam design allows controlled airflow while providing thermal insulation, vibration damping, and contamination protection. The silicone-treated paper liner protects the adhesive during storage and handling, ensuring consistent performance upon application. This product is specifically formulated for industrial and occupational use in electronics manufacturing, automotive assembly, appliance manufacturing, and construction applications.
