We developed 3M™ Lead Foil Tape 421 as an electrically and thermally conductive tape. This highly conformable tape resists flame, moisture, weather, UV degradation, chemicals and radiation. Mated with an easy-release film liner, our malleable tape can be shaped into complex or detailed patterns or die-cut into specific shapes to meet assembly and manufacturing process needs.

3M 421 Features:
  • Conformable tape resists flame, moisture, weather, UV degradation, and many chemicals
  • Performs over a wide variety of temperature conditions and is heat reflective
  • Heat and light reflective tape protects insulates and enhances lighting efficiency
  • Can be die-cut into specific shapes for assembly and manufacturing processes
  • The rubber-based adhesive combined with the rugged, durable backing provides long service life
