Premium 3M urethane foam tape with acrylic adhesive for industrial sealing, cushioning, and vibration damping applications. 1 inch x 18 yard rolls with 250 mil thickness.
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 engineered to provide superior cushioning and damping characteristics while maintaining excellent adhesion to multiple substrates. The charcoal gray, 0.250 inch thick soft foam design helps seal out air, dust, and light when compressed, making it ideal for a wide range of industrial applications including electronics, automotive, and construction industries.
The tape features 3M™ Adhesive 430, a modified acrylic pressure-sensitive adhesive that provides high initial quick-stick to various surfaces and substrates while offering excellent chemical resistance and shear holding strength. The adhesive performs reliably at temperatures up to 180°F (82°C) in the short term and 150°F (70°C) long term, making it suitable for demanding industrial environments. The open-cell foam construction allows for proper airflow while providing thermal insulation barriers and protection against contamination.
Each case contains 9 rolls of 18 yards length and 1 inch width, providing ample material for extensive industrial applications. The silicone-treated paper liner protects the adhesive and ensures clean, attractive application. This tape is designed for industrial and occupational use only, meeting rigorous standards for workplace applications including sound dampening, vibration absorption, and component protection in electronic equipment, automotive dashboards, aircraft lights, and door/window seals.
