Built to Silence, Engineered to Endure

Q: What’s the difference between this and 3M™ GPT020?

While GPT020 is a structural bonding tape, 435 is optimized for vibration and acoustic damping in thermally stressed zones — they complement one another.

Q: Is this suitable for flexible printed circuit (FPC) bonding?

Yes. It’s engineered for thermal stability and high surface adhesion , making it perfect for FPC applications.

Q: Can Eko-Tech provide this tape in custom formats?

Absolutely! We offer custom lengths, widths, die-cut shapes, kiss-cut pads, and spooled formats .

Q: What is the main advantage of 3M™ Tape 435 over standard damping tapes?

3M™ 435 combines thermal endurance and low outgassing with exceptional vibration control , even in critical environments.

When high heat and vibration collide, performance hinges on precision. 3M™ Vibration Damping Tape 435 is engineered to minimize acoustic noise and absorb vibrational energy in extreme environments up to 260°C (500°F). With 3M™ Ultra High Temperature Acrylic Adhesive 100HT, this clear, double-coated tape bonds to high surface energy (HSE) metals and plastics, providing lasting adhesion under thermal and mechanical stress.

Backed by a 3.6 mil heat-stable nonwoven liner, the 435 tape ensures optimal stability during converting processes like die-cutting and kiss-cutting. And with Eko-Tech’s full-service tape converting capabilities, your project receives a customized, ready-to-use material designed to reduce production complexity and enhance performance.
