3M™ Single-Sided Foam Tapes
Discover the Power of 3M™ 4318 – Single-Coated Urethane Foam Tape
3M™ 4318 is a high-performance single-coated urethane foam tape designed for applications where extreme temperature resistance and secure adhesion are essential. Withstanding short-term exposure up to 260°C (500°F), this tape excels in demanding environments like solder reflow and high-temp electronics assembly. Whether you’re bonding flexible printed circuits (FPCs) or adhering to high surface energy (HSE) metals, 3M™ 4318 delivers superior performance. It also features excellent holding power, high adhesion, and minimal outgassing, making it ideal for precision electronics and heat-intensive manufacturing.
