In 1938 Roy J. Plunket, a recent hire at DuPont, discovered polytetrafluoroethylene (or Teflon)—a fluoropolymer that led to the invention of synthetic rubber. [2] His early discovery led 3M scientists to develop the formula for Scotchgard, discovered by accident in 1953 when Joan Mullan—a 3M lab technician—spilled a few drops of a fluorochemical liquid destined for rubber jet fuel hoses ...
Shoe Goo was created in part in 1972 by Lyman Van Vliet, a 45-year-old senior executive at Hughes Aircraft Co. [1] [2] As a frequent tennis player, Van Vliet was dissatisfied with the durability of the soles of his tennis shoes and sought a method to extend their life by repairing them.
Scotch-brite. Scotch-Brite is a line of abrasive products produced by 3M.The product line includes scouring pads and tools for home uses such as dish washing and scrubbing, as well as various types of surfaces for industrial applications, such as discs, belts, and rotating brushes, with varying compositions and levels of hardness.
Sherman and coworkers were initially assigned to develop a rubber that could be used for jet fuel hoses. [2] A sample of a fluorochemical rubber was accidentally spilled on an assistant's shoe. After exhaustive attempts to remove the rubber failed, Sherman realized that the material could be used as a repellant for oil, water, and other solvents.
Alginate is used as an ingredient in various pharmaceutical preparations, such as Gaviscon, in which it combines with bicarbonate to inhibit gastroesophageal reflux. [citation needed] Sodium alginate is used as an impression-making material in dentistry, prosthetics, lifecasting, and for creating positives for small-scale casting. [citation needed]
The Goodyear welt process is a machine-based alternative to the traditional hand-welted method (c. 1500) for the manufacture of footwear, allowing them to be resoled repeatedly. The upper part of the shoe is shaped over the last and fastened on by sewing a leather, linen or synthetic strip (also known as the "welt") to the inner and upper sole.
D3O has various applications, such as in electronics (low-profile impact protection for phones, laptops, and other electronic devices), [20] sports (protective equipment), [21] motorcycle riding gear, [22] defence (helmet liners and body protection; footwear) [23] and industrial workwear (personal protective equipment such as gloves, knee pads and metatarsal guards for boots).
More than 150 different monomers can be combined within this family to give materials with extremely different properties. [2] These plastics are biodegradable and are used in the production of bioplastics. [3] They can be either thermoplastic or elastomeric materials, [citation needed] with melting points ranging from 40 to 180 °C. [citation ...
