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".
