Duct tape, in the USA and Canada, is a vinyl, fabric-reinforced, multi-purpose adhesive tape with a soft and tacky pressure sensitive adhesive. It is generally silver or black in color but many other colors and transparent tapes have recently become available. With a standard width of 17⁄8 inches (48 mm), duct tape was originally developed during World War II in 1942 as a waterproof sealing tape for ammunition cases.[1][2] Permacel, then a division of Johnson & Johnson, used a rubber-based adhesive to help the tape resist water and a fabric backing to facilitate ripping. Because of these properties, it was also used to quickly repair military equipment, including jeeps, guns, and aircraft. In Canadian military circles, this variant is known as "gun-tape", typically olive-green, and also known for its resistance to oils and greases. Duct tape is also called "100 mph tape" in the military [3], due to the fact that soldiers often refer to something that exceeds expectations as "High Speed."
After the war, the housing industry boomed and people started using duct tape for many other purposes. The name "duct tape" came from its use on heating and air conditioning ducts, a purpose for which it, ironically, has been deemed ineffective. Its strength, low cost, and remarkable versatility make it a household staple throughout the USA for temporary repairs and general-purpose use.
Common Uses
Duct tape's versatility and holding power are evidenced by its nickname in engineering circles: "the ultimate material." It is commonly used in situations that require a strong, flexible adhesive, particularly when exposure to the elements is a concern.
Duct tape is sometimes used by musicians and on film sets and in theaters, although a more specialized product, commonly known as gaffer tape in entertainment circles, is preferred as it does not leave a sticky residue when removed and is more easily torn into thin strips for precise application.
Usage in spaceflight
NASA engineers and astronauts have used duct tape on many occasions 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 was made using duct tape and other items on board Apollo 13, with the ground crew relaying directions to the spacecraft and its crew. The lunar module CO2 scrubbers started working again, saving the lives of the three astronauts on board.
Keith Canfield, 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 longer fenders for the lunar rover, reducing the rooster tails of lunar dust as they drove.[5].
In a 2001 NASA manual for spaceflight operations aboard the International Space Station, duct tape is even called for in case of "acute psychosis" during a space mission; NASA procedures call for the use of duct tape to restrain the affected astronaut. [6]
Usage on ductwork
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 use anything but 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 fail.[7] Its use in ducts has been prohibited by the state of California[8] and by building codes in most other places in the U.S. However, metalized and aluminum tapes used by professionals are still often called "duct tapes."
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 annually sponsors a competition that offers a college scholarship to the person who creates the most stylish prom formal wear made from duct tape. The number of uses to which duct tape can be put is a source of humor (many of these are collected in books by "The Duct Tape Guys"). One of Duck Products previous competitions was for vehicles covered in duct tape called "Stuck in Traffic". Entries included rabbits, a castle, a van decorated as Van Gogh's Starry Night (titled VanGo), and won by a truck called the Dragonracer (pictured) - a half dragon, half two-toned race car.
Some people enjoy making novelty items out of duct tape or decorating objects with it. Increased interest in creating these novelty and fashion pieces (such as duct tape prom dresses and handbags) has given rise to designer duct tape handbags, wallets, belts and related items. Various companies, like Duct Tape Revolution and Duct Bills now make wallets, bags and other accessories from the tape.
A medical study announced on major news networks on October 15, 2002, stated that application of duct tape can be used as an effective treatment for warts.[9] This treatment is often called by the name duct tape occlusion therapy. A more recent study claimed to have debunked these findings, pointing out the original researchers didn't actually examine participants to determine if the warts were in fact gone, but instead phoned participants and asked.[10] In the 2006 study of 103 children [Haen et. al.], duct tape did not perform significantly better than a placebo. This study compared clear duct tape, applied six nights a week to corn pad placebos, which were applied one night a week. In a study released in 2007, a study among older adults found duct tape helped only 21% of the time and was no better than moleskin, a cotton-tape bandage used to protect the skin. However, researchers used transparent duct tape that unlike the gray duct tape does not contain rubber. "Whether or not the standard type of duct tape is effective is up in the air," said Dr. Rachel Wenner of the University of Minnesota, who started the new study as a medical student. "Theoretically, the rubber adhesive could somehow stimulate the immune system or irritate the skin in a different manner." [1] The Wenner study was published in the March 2007 issue of Archives of Dermatology.
Duct tape is used extensively in the creation and identification of weaponry used by the Society for Creative Anachronism. The official SCA Weapons Standards is not specific, but duct tape is commonly known as the preferred material.
The epigram "duct tape is like The Force – it has a light side and a dark side, and it binds the Universe together" has been attributed to science fiction fan Carl Zwanzig. Red Green of The Red Green Show refers to duct tape as "the handyman's secret weapon" and says that, "If you have duct tape and you need money, you're better off than if you have money and need duct tape". The fictional television character MacGyver and the various members of the A-Team were also famous for inventive use of duct tape.
One of the catch-phrases of Tim Allen in his sit-com persona of Tim 'The Toolman' Taylor is "if you can't fix it, 'duck' it!".
Duct tape is sometimes used to wrap around tennis balls to make them behave more like a cricket ball. It is a less common practice to use duct tape as electrical tape, and it is not really suitable for that purpose.
In 2006, Rippedsheets.com introduced a fully inkjet printable sheet of duct tape that is coated to print in high resolution.
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 wacky 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 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.
Duct tape is also an effective gag when smoothed over a persons mouth or lips. It is frequently used in BDSM[citation needed].
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.[11]
Etymology
The origin of the term "duct tape" is the subject of some disagreement.
One view[12][13] is that it was called "duck tape" by WWII soldiers because it was made from cotton duck, which their tents, tarpaulins, ponchos and other equipment were made from. The word "duck" was commonly used for camping equipment fabrics until synthetics replaced cotton. Some suggest that 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 tents were forgotten and ductwork needed sealing, not ammunition cases. 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 version. The OED 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 of 2003. Safire cites use of the term "cotton duck tape" in a 1945 ad for surplus government property.
The other view is that "duct tape" is the original term, since there are many documented uses of that term which pre-date all documented uses of the term "duck tape" for the adhesive-backed product (other than Safire's 1945 ad), and that there is no written evidence supporting the WWII story.[14] Some proponents of this view accept the idea that there was an earlier non-adhesive "duck tape", but claim that people have just confused the effectively identical pronunciation of two similar but unrelated products through the process of elision, and that the rest of the "duck" etymology is folklore or fabrication. This view was summarized most notably in a Boston Globe article by etymologist Jan Freeman, also in March of 2003.
Different meaning in Australia
The term duct tape can lead to confusion between people more familar with the North American usage of the term and those from regions such as Australia and New Zealand; some Australians and New Zealanders refer to a completely different type of tape as duct tape, as shown right. This duct tape is a 48 mm (~2 in) wide PVC tape (usually silver in color) with no cloth backing and much weaker clear adhesive. Duck brand cloth-backed tape in Australia is labeled as Power Tape (a purely promotional term), and other cloth-backed tapes are generally labeled as cloth tape or gaffer tape. The use of this definition varies between Australians; many refer to duct tape as the same product as is sold in North America.
Names in other countries
Other names for duct tape have been documented at length by The Duct Tape Guys.
In the UK the common expression is 'gaffa tape' or 'gaffer tape', particularly in the musical entertainment industry. It is commonly used by roadies for everything from keeping cables in place to repairing drumskins.
A similar kind of tape in use with the German armed forces is colloquially known as "Panzerband" or "Panzer-Tape" ("tank tape" in English).
In Finland, duct tape is commonly known as "Jeesusteippi" ("Jesustape" in English) as "it does miracles" or "roudarinteippi" ("roadie's tape").
In The Netherlands, duct tape is known as "Krachttape" ("powertape" in English).
"MacGyver Tape" has become a popular name for Duct Tape, especially considering that MacGyver uses the tape in every way possible. Viewers of The Red Green Show in Canada are probably familiar with Duct Tape as "The Handyman's Secret Weapon" or the "Universal Adapter," based on the catchphrases of the fictional main character, Red Green.
Duct tape is known as "Michigan Chrome", since many people there use it to repair their bumpers.
In Portugal, it is usually referred as an "adesivo" (from the Portuguese verb "aderir" - to adhere in English - meaning "something that adheres").
