Industrial-grade 1/2 inch x 18 yard urethane foam tape with acrylic adhesive for sealing, cushioning, and sound dampening in electronic and automotive applications. 250 mil thickness, charcoal gray, case of 18 rolls.
3M™ Urethane Foam Tape 4314 is a premium conformable, low-density, open-cell foam tape featuring a pressure-sensitive acrylic adhesive on a single side. This charcoal gray tape measures 1/2 inch wide by 18 yards long with a 250 mil thickness, making it ideal for industrial sealing, cushioning, and sound dampening applications. The tape is comprised of soft, conformable foam that helps seal out air, dust, light, and moisture when compressed, while the acrylic adhesive provides high initial quick-stick to multiple substrates with excellent shear strength and temperature performance up to 150°F long-term and 180°F short-term.
The open-cell construction of this foam tape offers exceptional cushioning characteristics and high absorbency, making it perfect for electronic equipment applications such as printers, keyboards, computers, aircraft lights, and automotive dashboards. When compressed 50%, the open-cell design creates an effective air barrier while maintaining breathability for components that require airflow for cooling. The silicone-treated paper liner protects the adhesive during storage and handling, ensuring consistent performance throughout the product's 24-month shelf life.
This industrial-grade tape is engineered for professional use with outstanding chemical resistance and shear holding strength. It provides an attractive, clean appearance after application and continues to build adhesion strength over time, typically reaching satisfactory adhesion within 20 minutes. The case includes 18 rolls, making it suitable for high-volume industrial operations, construction projects, and manufacturing environments where reliable sealing and vibration dampening are critical.
