Duct tape

Duct tape or duck tape is cloth- or scrim-backed pressure-sensitive tape often coated with polyethylene. There are a variety of constructions using different backings and adhesives. One variation is gaffer tape designed to be cleanly removed, while duct tape is not. Another variation is heat-resistant duct tape useful for sealing heating/ventilation/air-conditioning (HVAC) ducts, produced because standard duct tape fails quickly when used on heating ducts. Duct tape is generally gray or black but also available in other colors.

During World War II, Revolite, then a division of Johnson & Johnson, developed an adhesive tape made from a rubber-basedadhesive 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]

[hide]  *1 History and etymology  ==History and etymology[ edit] == The first material called "duck tape" was long strips of plain cotton duck cloth used in making shoes stronger, for decoration on clothing, and for wrapping steel cables or electrical conductors to protect them from corrosion or wear.[2]  For instance, in 1902, steel cables supporting the Brooklyn Bridge were first covered in linseed oil then wrapped in duct tape before being laid in place.[3]  In the 1910s, certain boots and shoes used canvas duck fabric for the upper or for the insole, and duck tape was sometimes sewn in for reinforcement.[4]  In 1936, the US-based Insulated Power Cables Engineers Association specified a wrapping of duck tape as one of many methods used to protect rubber-insulated power cables.[5]  In 1942, Gimbel's department store offered venetian blinds that were held together with vertical strips of duck tape.[6]  All of these forgoing uses were for plain cotton or linen tape that came without a layer of applied adhesive.

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.[7]  In 1930, the magazine Popular Mechanics described how to make adhesive tape at home using plain cloth tape soaked in a heated liquid mixture of rosin and rubber from inner tubes.<sup class="reference" id="cite_ref-8" style="line-height:1;unicode-bidi:-webkit-isolate;font-size:11.1999998092651px;">[8]

In 1925 this became the Scotch brand masking tape. In 1930, Drew developed a transparent tape based on cellophane, called Scotch Tape. This tape was widely used beginning in the Great Depression to repair household items.<sup class="reference" id="cite_ref-Carey_9-0" style="line-height:1;unicode-bidi:-webkit-isolate;font-size:11.1999998092651px;">[9]  Author Scott Berkun has written that duct tape is "arguably" a modification of this early success by 3M.<sup class="reference" id="cite_ref-10" style="line-height:1;unicode-bidi:-webkit-isolate;font-size:11.1999998092651px;">[10]  However, neither of Drew's inventions was based on cloth tape.<sup class="reference" id="cite_ref-Carey_9-1" style="line-height:1;unicode-bidi:-webkit-isolate;font-size:11.1999998092651px;">[9]

During World War II, a team headed by Revolite's Johnny Denoye and Johnson & Johnson's Bill Gross developed a new adhesive tape for the US military, intended to seal ammunition cases against moisture.<sup class="reference" id="cite_ref-11" style="line-height:1;unicode-bidi:-webkit-isolate;font-size:11.1999998092651px;">[11]  The tape was required to be ripped by hand, not cut with scissors. According to Johnson & Johnson, the idea came from an ordnance-factory worker—and mother of two Navy sailors—named Vesta Stoudt, who worried that problems with ammunition-box seals would cost soldiers precious time in battle. She wrote to President Franklin D. Rooseveltin 1943 with the idea to seal the boxes with a fabric tape, which she had tested at her factory. The letter was forwarded to the War Production Board, who put Johnson & Johnson on the job.<sup class="reference" id="cite_ref-12" style="line-height:1;unicode-bidi:-webkit-isolate;font-size:11.1999998092651px;">[12]  Their new unnamed product was made of thin cotton duck tape coated in waterproof polyethylene (plastic) with a layer of rubber-based gray adhesive ("Polycoat") bonded to one side.<sup class="reference" id="cite_ref-Safire2003_6-1" style="line-height:1;unicode-bidi:-webkit-isolate;font-size:11.1999998092651px;">[6] <sup class="reference" id="cite_ref-Jumbo_13-0" style="line-height:1;unicode-bidi:-webkit-isolate;font-size:11.1999998092651px;">[13] <sup class="reference" id="cite_ref-Inventions_14-0" style="line-height:1;unicode-bidi:-webkit-isolate;font-size:11.1999998092651px;">[14] <sup class="reference" id="cite_ref-Manco_15-0" style="line-height:1;unicode-bidi:-webkit-isolate;font-size:11.1999998092651px;">[15] <sup class="reference" id="cite_ref-16" style="line-height:1;unicode-bidi:-webkit-isolate;font-size:11.1999998092651px;">[16] <sup class="reference" id="cite_ref-17" style="line-height:1;unicode-bidi:-webkit-isolate;font-size:11.1999998092651px;">[17]  It was easy to apply and remove, and was soon adapted to repair military equipment quickly, including vehicles and weapons.<sup class="reference" id="cite_ref-Jumbo_13-1" style="line-height:1;unicode-bidi:-webkit-isolate;font-size:11.1999998092651px;">[13]  This tape, colored in army-standard matte olive drab, was nicknamed "duck tape" by the soldiers.<sup class="reference" id="cite_ref-Forbes_18-0" style="line-height:1;unicode-bidi:-webkit-isolate;font-size:11.1999998092651px;">[18]  Various theories have been put forward for the nickname, including the descendant relation to cotton duck fabric, the waterproof characteristics of a duck bird, and even the 1942 amphibious military vehicleDUKW which was pronounced "duck".<sup class="reference" id="cite_ref-19" style="line-height:1;unicode-bidi:-webkit-isolate;font-size:11.1999998092651px;">[19]

The Melvin A. Anderson Company of Cleveland, Ohio, acquired the rights to the tape in 1950.<sup class="reference" id="cite_ref-Inventions_14-1" style="line-height:1;unicode-bidi:-webkit-isolate;font-size:11.1999998092651px;">[14]  It was commonly used in construction to wrap air ducts.<sup class="reference" id="cite_ref-Forbes_18-1" style="line-height:1;unicode-bidi:-webkit-isolate;font-size:11.1999998092651px;">[18]  Following this application, the name "duct tape" came into use in the 1950s, along with tape products that were colored silvery gray like tin ductwork. Specialized heat- and cold-resistant tapes were developed for heating and air-conditioning ducts. By 1960 a St. Louis, Missouri, HVAC company, Albert Arno, Inc., trademarked the name "Ductape" for their "flame-resistant" duct tape, capable of holding together at 350–400 °F (177–204 °C).<sup class="reference" id="cite_ref-20" style="line-height:1;unicode-bidi:-webkit-isolate;font-size:11.1999998092651px;">[20]

Because the previously used generic term "duck tape" had fallen out of use, he was able to trademark the brand "Duck Tape" and market his product complete with a yellow cartoon duck logo. In 1979, the Duck Tape marketing plan involved sending out greeting cards with the duck branding, four times a year, to 32,000 hardware managers. This mass of communication combined with colorful, convenient packaging helped Duck Tape become popular. From a near-zero customer base Manco eventually controlled 40% of the duct tape market in the US.<sup class="reference" id="cite_ref-Manco_15-1" style="line-height:1;unicode-bidi:-webkit-isolate;font-size:11.1999998092651px;">[15] <sup class="reference" id="cite_ref-21" style="line-height:1;unicode-bidi:-webkit-isolate;font-size:11.1999998092651px;">[21]

The threads or fill yarn of the fabric may be cotton, polyester, nylon,rayon or fiberglass. The fabric is a very thin gauze called "scrim" which is laminated to a backing of low density polyethylene (LDPE). The color of the LDPE is provided by various pigments; the usual gray color comes from powdered aluminum mixed into the LDPE. There are two commonly produced tape widths: 1.9 in (48 mm) and 2 in (51 mm). Other widths are also offered.<sup class="reference" id="cite_ref-26" style="line-height:1;unicode-bidi:-webkit-isolate;font-size:11.1999998092651px;">[26]  The largest rolls of duct tape were made in 2005 for Henkel, with 3.78 inches (9.6 cm) width, a roll diameter of 64 inches (160 cm) and weighing 650 pounds (290 kg).<sup class="reference" id="cite_ref-Magazine2008_27-0" style="line-height:1;unicode-bidi:-webkit-isolate;font-size:11.1999998092651px;">[27] ==Common uses<span class="mw-editsection" style="-webkit-user-select:none;font-size:small;margin-left:1em;line-height:1em;display:inline-block;white-space:nowrap;unicode-bidi:-webkit-isolate;font-family:sans-serif;"><span class="mw-editsection-bracket" style="color:rgb(85,85,85);">[ edit<span class="mw-editsection-bracket" style="color:rgb(85,85,85);">] == Transparent duct tape<p style="margin-top:0.5em;line-height:17.9200000762939px;color:rgb(37,37,37);font-family:sans-serif;font-size:14.3999996185303px;">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.

It comes in a variety of colors, and is more easily torn into thin strips for precise application. In the UK, the term 'gaffer tape' is widely used to refer to duct tape, whereas the cloth-based product is known as 'camera tape'.<sup class="noprint Inline-Template" style="line-height:1;font-size:11.1999998092651px;white-space:nowrap;">[according to whom?]

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<span class="mw-editsection" style="-webkit-user-select:none;font-size:small;margin-left:1em;line-height:1em;display:inline-block;white-space:nowrap;unicode-bidi:-webkit-isolate;"><span class="mw-editsection-bracket" style="color:rgb(85,85,85);">[ edit<span class="mw-editsection-bracket" style="color:rgb(85,85,85);">] === <p style="margin-top:0.5em;line-height:17.9200000762939px;color:rgb(37,37,37);font-family:sans-serif;font-size:14.3999996185303px;">The product now commonly called duct tape should not be confused with special tapes actually designed for sealing heating and ventilation ducts. To provide laboratory 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 had defined duct tape as any fabric-based tape with rubber adhesive). The testing done shows that under challenging but realistic conditions, common duct tapes become brittle and may fail.<sup class="reference" id="cite_ref-lbl_28-0" style="line-height:1;unicode-bidi:-webkit-isolate;font-size:11.1999998092651px;">[28] <sup class="reference" id="cite_ref-walker_29-0" style="line-height:1;unicode-bidi:-webkit-isolate;font-size:11.1999998092651px;">[29]

Its use in ducts has been prohibited by the state of California<sup class="reference" id="cite_ref-30" style="line-height:1;unicode-bidi:-webkit-isolate;font-size:11.1999998092651px;">[30]  and by building codes in most other places in the US. However, higher quality metallized and aluminum tapes used by professionals for sealing ducts are still often called "duck/duct tapes". ===Usage in spaceflight<span class="mw-editsection" style="-webkit-user-select:none;font-size:small;margin-left:1em;line-height:1em;display:inline-block;white-space:nowrap;unicode-bidi:-webkit-isolate;"><span class="mw-editsection-bracket" style="color:rgb(85,85,85);">[ edit<span class="mw-editsection-bracket" style="color:rgb(85,85,85);">] === Improvised wheel fender extension with duct tape, Apollo 17<p style="margin-top:0.5em;line-height:17.9200000762939px;color:rgb(37,37,37);font-family:sans-serif;font-size:14.3999996185303px;">According to NASA engineer Jerry Woodfill, duct tape had been stowed on board every mission since early in the Geminidays.<sup class="reference" id="cite_ref-Atkinson2010_31-0" style="line-height:1;unicode-bidi:-webkit-isolate;font-size:11.1999998092651px;">[31]  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.
