CR180 - Military Specification
Cork Rubber Tape
"Cork-Tape" is an excellent
seal, ideal shim, and under most conditions, acts as a bi-metallic
insulator. It provides an attractive cushion for base of metal
and plastic electronic components, metal desk appliances such
as desk lighters, pen sets, and glass tops for desks, which also
gives the unit non-skid properties.
Cork-Tape is sponged synthetic cork and rubber with non-stretch
print cloth vulcanized to the material. CR-180 carries an extremely
high tack instant grab pressure-sensitive adhesive. Backing is
heavy, silicone treated non-transferable release paper. Most shapes
permit tape or sheet to be die-cut and left on the backing for
ready application on the production line.
CR-180 passes the requirements of Military Specification MIL-T-6841
and was tested and approved for usage by the government for sealing
plastic canopies over the cockpit on aircraft. It has non-crazing
properties used in conjunction with acrylic plastic.
The ground finish on "Cork-Tape" gives an attractive
appearance. Also, the close tolerance of this material gives wide
latitude to the number of its uses. CR-181 same except without
PSA.
A full length roll is 36" wide that can be custom slit to
desired widths. It is available in thicknesses of 1/32",
1/16", 3/32", and 1/8".
