3M™ 70006387271 Foil Tape, 36 yd L, 2 in W, Lead Foil Backing, Dark Silver

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.

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 surfaces 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
• Very good conformability
• Good thermal properties and will perform over a wide variety of temperature conditions (-60 to 225 deg F or -54 to 106 deg C), it has been used at higher temperatures for shorter duration
• Electrically and thermally conductive
• Can be die-cut into specific shapes
• This material when disposed of separately is classified as RCRA hazardous waste, please consult applicable federal, state and local regulations for proper disposal
• Elevated lead levels in water may result from long-term submersion of this product
