A Guide To Duct Tape



Duct Tape is​ a​ fabric based, adhesive material mainly used for sealing joints in​ sheet metal ductwork. This cloth tape, an​ indispensable item in​ tool kits, has polyethylene resin coatings on one side and a​ rubber based sticking material on the other side. Duct tape is​ nickname ‘the ultimate material’ because of​ its high holding power and versatility.

Duct tape originated in​ 1942, during World War II. Permacel, a​ former division of​ Johnson and Johnson Company, invented the tape as​ a​ waterproof material to​ seal ammunition cases. The tape, initially made from cotton duck, was also used to​ repair various military equipment including guns, aircrafts, and jeeps. After the war, the color of​ the tape changed from its original olive green to​ silver and the material was found very useful in​ the housing industry. as​ a​ result, the demand of​ this adhesive material increased great deal and it​ was made available to​ the public under the name duct tape.

Before the final product is​ made available, duct tape undergoes a​ serious of​ processes, which include adhesive compounding, adhesive application, coating, respooling and slitting, and packaging. Once the manufacturing processes are over, the duct tape is​ checked for quality as​ per the directions of​ the American Society for Testing and Materials.

Duct tape is​ available in​ a​ variety of​ colors, of​ which the most common are silver and black. This malleable and soft material usually has a​ width of​ 1.88 inches. Duct tape comes in​ various grades, which differ in​ the tensile strengths. The application varies as​ the grade varies. Commercial grade tapes are classified into utility, general purpose, and premium grades. There are specialty grades, which include nuclear tape for reactors and a​ ‘200-mile-an-hour’ tape for racecars.
