Tapes
3M
3M Antistatic Utility Tape 40 combines 3M’s remarkable antistatic
adhesive with a clear, one mil polyester film backing, and is perfect
for use in static-sensitive areas. An optional special pattern of
ESD symbols alerts users that this is the only tape that should be
used in static-safe areas.
At the heart of all 3M antistatic tapes is a unique conductive polymer
adhesive that suppresses static, both during unwind from the roll and
during removal from a surface. They generate less than 50 volts on
unwind from the roll or removal from a stainless steel surface, even
in extremely dry conditions of 10% relative humidity.
Use Antistatic Utility Tape 40 as a third hand to hold work orders, notes,
documentation, or instructions in place; to seal static shielding bags
and boxes containing electronic components; or to bundle DIP tubes
and JEDEC shipping trays. It can also be used to hold down obstructions
such as wires or attachments during manufacturing.
