403-20 is a 20 mil, Ultra High Molecular Weight Polyethylene (UHMW) film with an aggressive elastomeric adhesive. The UHMW film provides an excellent low friction, non-stick surface, in many ways similar to PTFE. The film has a very high tensile strength and is very tough and abrasion resistant. These tapes are used primarily in mechanical applications such as chute liners, wear pads and guide rails. They are also used as glide surfaces or pads on such items as a computer mouse.
