These products are black, pressure sensitive tapes using Ultra High Molecular Weight Polyethylene (UHMW) film with an aggressive permanent acrylic adhesive. The UHMW film provides an excellent low friction, non-stick surface-in many ways similar to PTFE. The UHMW film has a very high tensile strength and is very tough and abrasion resistant.
These tapes are used primarily in automotive applications such as squeak tape and sound deadening. They are also used in various mechanical applications such as chute liners, wear pads and guide rails.
