Description
Perma-Wrap Foam Insulation Tape is formulated from
the highest quality elastometric thermal insulation
material. It is manufactured in accordance with selected
specifications to meet the needs of today’s air conditioning
and refrigeration applications. It’s closed-cell construction
seals out air, retarding heat transfer and providing complete
insulation. The acrylic laminate adhesive allows for greater
service temperatures and a more secure bond that won’t
deteriorate with moisture.
Application
Perma-Wrap can be used on cold water pipes, chilled
water lines, and refrigerant lines, to prevent sweating and
condensation. It can also be used on hot water lines for
better insulation against heat loss. Keeps cold lines cold
and hot lines hot. Can be over-lapped or the edges can
be butted. Service temperatures can be as low as -20°F
with a high continuous temperature of 160°F and high
intermittent temperatures of 220°F.
Directions for Use
Apply Perma-Wrap by removing release paper as the tape
is spirally wrapped around the piping or fittings, press
firmly in place, and avoid stretching.
Pressure-sensitive adhesive adhere firmly and forms a
long lasting bond to metal surfaces.
For a faster and more efficient job, tape should be spiral-
wrapped to obtain a 50% over-lap. Additional layers build
up insulation to required thickness.
To insulate valves, tees, and fittings, cut small pieces of
tape and press into place until all metal is covered.
Overwrap with longer lengths for a durable and efficient
job.
