In 2003, chemical company BASF embedded nanoparticles of titanium dioxide into a nylon fabric, which can be used for sun protective clothing that maintains its UV protection when wet. [5] There is some indication that washing fabrics in detergents containing fabric brighteners, which absorb UV radiation, might increase their protective capability.
Industrial Insulation. Rigid polyurethane foam is used in various industries to provide thermal insulation to installations and pipes. In particular, the piping for district heating systems in Europe is primarily insulated using a pre-insulated pipes sandwich assembly composed of a steel heat service pipe, an insulating layer (polyurethane foam) and a polyethylene (PE) casing, which are bonded ...

Laundry detergent fluorescing under ultraviolet light. Optical brighteners, optical brightening agents (OBAs), fluorescent brightening agents (FBAs), or fluorescent whitening agents (FWAs), are chemical compounds that absorb light in the ultraviolet and violet region (usually 340-370 nm) of the electromagnetic spectrum, and re-emit light in the blue region (typically 420-470 nm) through the ...
Drop of water on 100% polyester textile. Waterproof/breathable fabrics resist liquid water passing through, but allow water vapour to pass through. Their ability to block out rain and snow while allowing vapour from sweat to evaporate leads to their use in rainwear, waterproof outdoor sports clothing, tents, and other applications.
In 1938 Roy J. Plunket, a recent hire at DuPont, discovered polytetrafluoroethylene (or Teflon)—a fluoropolymer that led to the invention of synthetic rubbers. [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 ...
