Friction tape on a tennis racket handle Friction tape is a type of woven cloth adhesive tape, historically made of cotton, impregnated with a rubber-based adhesive. Sticky on both sides, it is mainly used by electricians to insulate splices in electric wires and cables. The rubber-based adhesive provides a degree of protection from liquids and corrosion, while the cloth mesh protects against punctures and abrasion. It has been universally supplanted by PVC- based electrical tape.

Friction tape is commonly used to improve the grip on various sporting implements, including tennis racquets, baseball bats, and hockey sticks. It is also used similarly on the handlebars of bicycles, dirt bikes, lawnmowers, and other small machines that require gripping or steering.

This type of tape was often used to insulate soldered splices on knob and tube wiring. It was commonly referred to as "friction tape", and had the unique property of being sticky on both sides. Because of this, no matter how it was used it stuck to itself very readily. In the early 1940s, vinyl plastic emerged as a versatile material for a wide range of applications, from shower curtains to cable insulation.

In 1942, Gimbel's department store offered venetian blinds that were held together with vertical strips of duck tape. Glue backed or impregnated adhesive tapes of various sorts were in use by the 1910s, including rolls of cloth tape with adhesive coating one side. White adhesive tape made of cloth soaked in rubber and zinc oxide was used in hospitals to bind wounds, but other tapes such as friction tape or electrical tape could be substituted in an emergency.

Whether true or not, McCoy was known as a fast, "scientific" fighter who would cut his opponents with sharp blows. He reportedly would wrap his knuckles in mounds of friction tape, to better cut his opponents faces. He was listed # 1 Light Heavyweight of all time in Fifty Years At Ringside, published in 1958. He was also regarded as a formidable puncher, and was included in Ring Magazine's list of 100 greatest punchers of all time.

Griptape is the friction tape adhered to the topside of the deck to enable users to more easily maintain control of the board. There are many types of griptape. Some use standard skateboard griptape, although the griptape may wear out faster on fingerboards as they endure more moisture from the sweat and oils of a user's hands. There are also softer alternatives and grippy tape which is less harsh on a user's fingers allowing them to fingerboard for longer periods of time.

They are also used as slip agents in printing ink. Microcrystalline wax is used in such sports as ice hockey and snowboarding. It is applied to the friction tape of an ice hockey stick to prevent degradation of the tape due to water destroying the glue on the tape and also to increase control of the hockey puck due to the wax’s adhesive quality. It is also applied to the underside of snowboards to reduce friction and increase the gliding ability of the board, making it easier to control.

Where conductors entered a wiring device such as a lamp or switch, or were pulled into a wall, they were protected by flexible cloth insulating sleeving called loom. The first insulation was asphalt-saturated cotton cloth, then rubber became common. Wire splices in such installations were twisted together for good mechanical strength, then soldered and wrapped with rubber insulating tape and friction tape (asphalt saturated cloth), or made inside metal junction boxes. Knob and tube wiring was eventually displaced from interior wiring systems because of the high cost of installation compared with use of power cables, which combined both power conductors of a circuit in one run (and which later included grounding conductors).
