Duct tape, (NOT DUCK TAPE), is cloth- or scrim-backed pressure sensitive tape often sealed with polyethylene. There are a variety of constructions: backings, adhesives, etc. One variation is gaffer tape but differs in that gaffer tape was designed to be cleanly removed, while duct tape was not. It is generally silver or black but also available in other colors. In 1942 Revolite, formerly a division of Johnson & Johnson, originally developed an adhesive tape made from a rubber-based adhesive applied to a durable duck cloth backing. This tape resisted water and was used as sealing tape on ammunition cases during World War II.[1] Because of these properties, it was also used to repair military equipment quickly, including jeeps, firearms, and aircraft.
Common uses
Duct tape is commonly used in situations that require a strong, flexible, and very sticky tape. Some have a long-lasting adhesive and resistance to weathering.
A more specialized product, commonly known as gaffer tape, is preferred by gaffers in the motion picture and television industries, as it does not leave a sticky residue when removed. It comes in a variety of colors, and is more easily torn into thin strips for precise application.
Duct tape, in its guise as "racer's tape", "race tape" or "100 mile an hour tape" has been used in motorsports for more than 40 years to repair fiberglass bodywork (among other uses). Racer's tape comes in a wide range of colors to help match it to common paint colors. In the UK, it is usually referred to as "tank tape" in motorsports use.
Usage on ductwork
The product now commonly called duct tape should not be confused with special tapes actually designed for sealing heating and ventilation ducts: this is not recommended by manufacturers. To provide lab data about which sealants and tapes last, and which are likely to fail, research was conducted at Lawrence Berkeley National Laboratory Environmental Energy Technologies Division. Their major conclusion was that one should not use common duct tape to seal ducts. (They defined duct tape as any fabric-based tape with rubber adhesive.) The testing done shows that under challenging but realistic conditions, duct tapes become brittle and may fail.[2] Commonly duct tape carries no safety certifications such as UL or Proposition 65, which means the tape may burn violently, producing toxic smoke; it may cause ingestion and contact toxicity; it can have irregular mechanical strength; and its adhesive may have low life expectancy. Its use in ducts has been prohibited by the state of California[3] and by building codes in most other places in the U.S. However, metalized and aluminum tapes used by professionals are still often called "duck/duct tapes".
Usage in spaceflight
According to NASA engineer Jerry Woodfill, duct tape had been stowed on board every mission since early in the Gemini days. {{citation}}: Empty citation (help)
NASA engineers and astronauts have used duct tape in the course of their work, including in some emergency situations. One such usage occurred in 1970, when the square carbon dioxide filters from Apollo 13's failed command module had to be modified to fit round receptacles in the lunar module, which was being used as a lifeboat after an explosion en route to the moon. A workaround used duct tape and other items on board Apollo 13, with the ground crew relaying instructions to the flight crew. The lunar module's CO2 scrubbers started working again, saving the lives of the three astronauts on board.
Ed Smylie, who designed the scrubber modification in just two days, said later that he knew the problem was solvable when it was confirmed that duct tape was on the spacecraft: "I felt like we were home free," he said in 2005. "One thing a Southern boy will never say is, 'I don't think duct tape will fix it.'"[4]
Duct tape was also used aboard Apollo 17 to improvise a repair to a damaged fender on the lunar rover, preventing possible damage from the spray of lunar dust as they drove.[5]
Military usage
In military circles, there is a variant known as "shooters tape" or "gun tape", typically olive-green, known for its resistance to oils and greases.[citation needed] In the U.S. submarine fleet, it is called "EB Green," as the duct tape used by Electric Boat was green.[6] It is also called "duck tape," "riggers' tape," "hurricane tape," or "100-mph tape"[7][8]—a name that comes from the use of a specific variety of duct tape that was supposed to hold up to 100 miles per hour (160 km/h; 87 kn) winds. The tape is named so because it was used during the Vietnam War to repair helicopter rotor blades, thus earning the name 100-MPH tape.[9] Duct tape was also used during the Vietnam War to balance helicopter rotor blades.[10]
Alternative uses
Duct tape's widespread popularity and multitude of uses has earned it a strong place in popular culture, and has inspired a vast number of creative and imaginative applications.
Duck Products, the manufacturer of Duck brand duct tape (Duck Tape), annually sponsors a competition that offers a college scholarship to the person who creates the most stylish prom formal wear made from Duck Tape.
Duct tape occlusion therapy (DTOT): is a method intended to treat warts by covering them with duct tape for an extended period. The evidence for its effectiveness is poor;[12][13] thus it is not recommended as routine treatment.[14]
As a quick fix, duct tape can be used as a temporary bandage, until proper medical treatment and bandages can be applied to a wound.[15]
Recently, duct tape has proven the most effective fix to Apple's iPhone 4 dropped call issue, even over Apple's own rubber case.[16]
In popular culture
The Duct Tape Guys (Jim Berg and Tim Nyberg) as of 2005 have written seven books about duct tape. Their bestselling books have sold over 1.5 million copies and feature real and unusual uses of duct tape. In 1994 they coined the phrase "it ain't broke, it just lacks duct tape". Added to that phrase in 1995 with the publication of their book about lubricant WD-40 book was, "Two rules get you through life: If it's stuck and it's not supposed to be, WD-40 it. If it's not stuck and it's supposed to be, duct tape it". Their website features thousands of duct tape uses from people around the world ranging from fashions to auto repair. The combination of WD-40 and duct tape is sometimes referred to as "the redneck repair kit".
The Canadian sitcom The Red Green Show's title character often used duct tape (which he dubbed "the handyman's secret weapon") as both a shortcut to proper fastening as well as for unconventional uses. The series sometimes showcased fan duct tape creations. The series had a feature film based on it entitled Duct Tape Forever and several VHS/DVD compilations of the show's use of the tape have been released. Since 2000, series star Steve Smith (as Red Green) has been the "Ambassador of Scotch Duct Tape" for 3M.[17]
The Discovery Channel series MythBusters has featured duct tape in a number of myths that involve non-traditional uses. Confirmed myths include suspending a car for a period of time, building a functional cannon, a two-person sailboat, a two-person canoe (with duct tape paddles), wearable shoes, a leak proof water canister, rope, a hammock which can support the weight of an adult male, and constructing a bridge that spanned the width of a dry dock. In the episode "Duct Tape Plane," the MythBusters repaired (and eventually replaced) the canopy of a lightweight airplane with duct tape and flew it a few meters above a runway.
Etymology
The origin of the name of the product, "duck tape" or "duct tape," is the subject of some disagreement.
One view is that it was called "duck tape" by WWII soldiers either because it resembled strips of cotton duck (canvas) or because the waterproof quality of the tape contributed to the name, by analogy to the water-shedding quality of a duck's plumage. Under this view, soldiers returning home from the war found uses for duck tape around the house where ductwork needed sealing. Other proponents of this view point to older references to non-adhesive cotton duck tape used in Venetian blinds, suggesting that the name was carried over to the adhesive product. The Oxford English Dictionary says that perhaps "duct tape" was originally "duck tape". This view is summarized most notably in a New York Times article by etymologist William Safire in March 2003. Safire cites use of the term "cotton duck tape" in a 1945 advertisement for surplus government property.[18] The Brooklyn Daily Eagle uses the term "duck" in 1902 quotation for "100,000 yards of cotton duck tape" being used to protect the cables of the Brooklyn Bridge.[19] Thus a fabric duck tape was available to which an adhesive could have been added.
Different meaning in Australia and New Zealand
The term duct tape can lead to confusion between people more familiar with the North American usage of the term and those from regions such as Australia and New Zealand, where a different type of tape is often sold as duct tape: a PVC tape without a fabric backing. [1]
